Perfect Dark

Hint: The Duel: Easy mission:Play the mission under the Special Agent or Perfect Agent difficulty setting with the laptop gun (or after enabling the "All guns in solo" cheat). Start the level against the dataDyne guard. If you do not have the "Invincible", "Supershield", or "Jo shield" cheats enabled, run behind the wall. Equip your laptop gun, set it as a sentry turret, and throw it in the middle of the holograph room. The dataDyne guard will die, then Johnathon will be mauled by it as he plays with his magnum, and Trent Easton will do the same.

Collect all the weapons in the solo missions and achieve a Bronze rating or higher for each weapon at Firing Range.

To complete the Duel mission in under 1:00, use the following trick. Enable the "All weapons" and "Invincible" codes. Start a duel and when it begins, take out your Remote Mines. After that, go near your opponent but not too close or he will run at you. Start throwing all the Remote Mines that you have. If you run out of Remote Mines, use Proximity Mines, and use a few with the Remote Mines already attached to him. When the mines start detonating, they should kill all three of your opponents with the message "Well done! you were too quick for him." You can also use anything that explodes, as well as a laptop gun as a sentry.

When you have earned the duel mode, you face Jonathan in the "Special Agent:" and "Perfect Agent" difficulty settings. Defeat him easily by finishing a easy level, such as dataDyne Central in co-op mode with friendly-fire disabled. Go to the duel and Jonathan cannot shoot you. However, he can kick so keep yourself at a distance. You cannot shoot him either, unless you use the aimer. This works more than once, so you do not have to complete another mission every time you face him.

To complete the mission under the Perfect Agent difficulty setting, use a laptop gun and set it up it the middle of the room. Note: This will not unlock the gold star on the mission board.

Hint: Defeating the Skedar Leader:From the start, use your High-Impact Calisto conservatively throughout the entire level to save all pistol ammo for the Double Phoenix. The Phoenix will appear at the large gap after destroying all five pillars. When you reach the Boss, persistently fire explosive rounds at him. When he fires a rocket, it will explode in his face. Also, he will not have time to summon more Skedar. Knock out all the shards and kill them.

Use the following trick to defeat the Skedar Leader without the Phoenixes. Attach the target amplifiers to all of the pillars, but instead of blowing up the other ones, just play through the rest of the level. When you reach to the suspended animation Skedar army, defeat them and pick up all of their Maulers. Then, go to the Skedar Leader and select the Mauler. Switch it to charge-up shot. When he bends down to recharge his shield, shoot the prongs on the big symbol behind him, starting with the bottom ones. It should take about one blast to destroy each prong. Once the last big prong is destroyed, it will fall down and skewer him. This makes it easier to unlock the R-Tracker and All Guns cheats.

Hint: Killing Skedar:To kill Skedar in one or two shots, shoot the small snake-like thing hanging out the back of their head.

Hint: Multi-player mode:

Keep moving -- standing still makes you an easy target for automatic weapons

When playing against sims (Meat, Easy, or Normal varieties), shoot weapons and ammo boxes out of their normal respawn locations then collect them. The weapon or ammo will respawn where you picked it up. Simulants will think that it has been picked up and pass it by without looking.

When with your back to a corner and low health, arm a grenade or N-Bomb by holding Z. Run at your opponent -- there is a chance you can also kill him.

When using cloaking devices, go for easy kills by using combat knives. Slashing with the knives will allow you to stay cloaked but give you a chance to get in some damage.

The larger your character, the faster you go. Mr. Blonde is the fastest and the aliens are the slowest. The best character to use is a Maian soldier with Biotecnition head.

If you are holding double guns you will take double damage.

When playing "one hit kills" in multi-player mode set your handicap all the way down (10) to get more experience points and gain levels faster.

Hint: Human bomb in multi-player mode:During a multi-player game with Remote Mines, preferably against many simulants, have your teammate come over to you. Place some mines on his/her body. If it is a simulant, have him/her attack the enemy, and if it is a human have them attract a large group of enemies. To avoid a kill penalty when your teammate dies, have your teammate fight as many enemies as possible at once then as soon as he dies, detonate. You will not be penalized for a negative kill -- getting killed is better than "suiciding" or team-killing and you can take out many enemies at once.

Hint: Headshots in multi-player mode:In Area 52, go to the room with the metal door and metal windows. Stand in the middle and look towards the door. You should see a line in the bricks to the right and left of the door (use the higher one). Aim equal to that height at the door. Next, aim in the door opening but slightly to the right, so when someone (mainly sims) opens the door, you can shoot them in the head. Note: Sometimes they enter towards the left.

In the Facility level, one of the rooms down the hallway has a large pillar to the right when you enter. You can climb up the pillar and set camp, especially if radar is off. You will have a perfect headshot to players who do not know about it.

Hint: Knife kills in multi-player mode:Since you really cannot get a headshot with the primary mode of the combat knife, hit them in the back instead. Doing this results in a lot more damage, and will usually kill a 100% health opponent.

Hint: Easy kills in multi-player mode:Use the following trick to upgrade your character easily. Set up a Capture The Case game with eight meat sims on your team. Set all weapons to remote mines and have the case in the bathroom on the Facility. Have all the sims to guard the case. Place one mine in between the sims, one mine on the ammunition case, one on the other ammunition case, and two on each door (one on each side of the door). Leave the doors open and run down the hall. Blow up the mine and it should keep doing that until you quit. Note: Set the time and scores to no limit.

Set one weapon slot to the combat knives. Kill someone with the poison knives. While they are falling to the ground, keep filling them up with the poison knives. When they revive, they will keep taking damage until they are dead.

Hint: Three Golden Magnums in multi-player mode:Play with a friend in cooperative mode. Go to the Maian SOS level and kill the man with the two Golden Magnums. Have one player get one Gold Magnum and the one player get the other one. One person should have one Gold Magnum and the other should have two. Note: This is more fun with the "Unlimited ammunition" cheat enabled.

Hint: Get all 4 stars in multi-player mode quickly:Select your custom character in multi-player mode. Make sure there are only two human players. Select tranquilizer weapons as all the weapons. Start the game and have player two hide in a corner, facing the corner. Have player one get a tranquilizer and find player two. Player one should shoot the whole "clip" into player two's neck. Player two will die. End game and player one should have the 4 stars: Accuracy, Killmaster, Survivor and Headshot.

Go to advanced setup and turn on one hit kills and enable another human player. Set all the weapons to Farsights and set the limits of the game to one kill. Then, just run and pick up a gun, hold B to switch the settings to target locator, and hold R to aim for the head. With one shot, the game is over and you will earn all four medals.

Hint: Raising multi-player characters rank quickly:Set all the weapons to Callisto, four Simulants to perfect, and the stage to the Facility (in advanced setup). Then, keep restarting your game until you start in the airducts or somewhere nearby. Make sure no simulants are near you. Get the Callisto next to the urinal in the bathroom and place yourself against the door. Set the gun to high impact shells. When someone tries to open the door they will not be able to because you should be against it. You will be able to shoot them repeatedly through the doors without giving them a chance, because the game will not let them restart in the airducts. Keep doing this until your rank is as high as it will go (level 1).

An easier way to level up in multi-player mode is do all the same things as explained above, but use the Farsight XR-20. It has x-ray vision which makes it easier to get kills and medals.

This trick requires two human players, and eight of the best Simulants available. Exploding weapons, Callisto, or FarSight work best. Have player two order all Simultants to stand close by. This works best in locations with doors. Have player two and Simulants gather outside your door. Player two should walk up to you and the Simulants will follow. Open the door for exploding weapons and shoot through the door if using Callisto or FarSight.

Hint: Mystery ammo box in multi-player mode:When in the Warehouse in multi-player mode, fall through the hole that has item 5 next to it. When you look up past the hole (where another item 5 is present), there will be a question mark grating with an ammo box on top. You can also use the sniper rifle to zoom in on it, or the Farsight to x-ray through. There does not seem to have an entrance to it and you cannot shoot through it to knock down the box.

Hint: More ammo in multi-player mode:Use the following trick to get a slight advantage when in the multi-player mode with your friends. Certain guns use the same ammo, such as pistols. Some of those guns have a larger clip than others, such as the Mauler. Switch to that gun and collect all of the ammo you can possibly get (it helps to get doubles). When done, switch to another gun with a smaller clip, such as any of the Falcon 2's, the Phoenix, or the Magsec 4. You will have more ammo than you usually would. This also works with Cyclones, Laptop Guns, CMP150s, Callisto NTGs, and RCP 120s, as well as Devastators and the grenade mode of the Superdragon.

Hint: Finding the hill in King Of The Hill mode:When playing King Of The Hill mode, follow the simulants to the hill

Hint: Completing all challenges easily:Have player one select "Combat Simulator" and choose "Advanced Setup". Have player two press Start. Have player one select "Load Settings" on the advanced setup menu, but do not select any setup yet -- just remain at the "Load Game Settings" menu. Have player two select the challenge to be completed in the advanced setup menu. Then, have player two press Start until the green "...and waiting" screen appears. Have player one select the desired game settings in the "Load Game Settings" menu. Note: You must have a custom or pre-made setup -- you cannot alter it after it is loaded. Player one can drop out or join the game -- it does not matter, however, staying in will give you two stars instead of just one. This trick can also be used to get the three or four player challenges.

Go to the Combat Simulator with two controllers. Have player one create a simple scenario, such as one kill in one minute against a meatsim. Save that scenario and go to "Load Settings". Highlight the new scenario but do not press any buttons. Have player two (who should have the advanced menu on screen) press Right until the list of challenges is displayed. Do not leave the advanced setup menus. Remain there and go through the four menus (Setup, Character, Other Options, Challenges) to find the challenge to complete. Have that player select it and press A until the "...Waiting" screen appears. Then, have player one press A on the created scenario, followed by Start. The created scenario will begin. Win the scenario and you will have the challenge that was selected beforehand completed.

Go to advanced setup. Have one player load a custom saved game while another player picks a certain challenge. Once the player picks the challenge and clicks "OK" the other player should pick a saved game. Both players should press Start. When you play, you will be playing the saved game, but it will count as a star for challenges.

Go to the challenge screen in multi-player mode. Create a game with a meat sim in Area 52 and one kill. Save the game. Press Start on controller two. Have player one go to the challenge screen and press A. The game will ask you to accept the challenge, Do not stay at that screen. Have player two load the saved challenge then load it and accept the challenge. The challenge will start with the saved game, and it will count as completing the challenge.

Hint: Over 10,000 kills:Select the Capture The Case level with you against eight Meatsims. Set the weapons to be all some kind of mine. Keep starting the game until the sim's base is at the restroom. Stand outside and place a few mines. At some point after you have done this two or three times, things will automatically explode from nothing. In an hour you can get as many as 10,000 kills or more. Note: The explosions may die down or stop if this happens just place a few more mines there.

Hint: Fast running:Turn left until your cursor is approximately 30 degrees to the left of where you want to run to. Then, simply hold Analog-stick Forward (Up) and hold C-Right. You will run diagonally, but once you get used to it, you will be able to get to places faster. This is useful for running from friends in multi-player mode and also for meeting target times in single player mode. This can also be reversed. Simply swap the left and right directions.

Hint: Circle attacks:This is a simple move, but priceless to master. Hold Analog-stick Left then hold C-Right. You will circle an invisible point in the center. Practice doing this around a crate, trying to keep your gun cursor/sights on top of it. Also, try doing this with holding Analog-stick Rightand C-Left to circle in the other direction. This makes will make you harder to hit, but will keep the enemy in your sights at the same time. If your sight starts to drift from your target, just adjust your angle on the Analog-stick.

Hint: 1000% handicap advantages:In advanced setup, set the handicap up to 1000%. You will not die as much, and can get better medals.

Hint: Getting more ammunition:When you see a guard in any level, switch to unarmed and then to disarm. Run up to the guard and steal his gun. Sometimes they will just stand there with their hands up. If you let them stand there long enough and if you walk around, they sometimes will pull out a Falcon 2 and try to shoot you. This allows you to possibly get twice the amount of ammunition, for example some for a CMP150 and some for your Falcon 2.

Hint: Getting weapons easier:Find a person with the gun that you want. Kill the person with the gun and abort. The gun will stay in the game's inventory. For example, if you kill Elvis when he is using the Phoenix, he will drop it. Pick it up and you will be able to use the gun.

Hint: Silent reload:If you want to reload without anybody hearing, press Start, highlight the ammunition you need, and press "Equip".

Hint: Quicker reloads:Just switch to the weapon before the current weapon, then quickly switch back. Practice doing this to get it faster each time. This will save time and health. It will not be as fast asGoldenEye 007, but it is better than the regular method. Note: This does not work with the shotgun or crossbow, is not recommended with the Laptop Gun.

One of the main drawbacks to the shotgun and crossbow weapons is how they take too long to reload, leaving you vulnerable to attack while your character goes through the reload animations. However, there is a quick and convenient way to shorten the reload time. While your character is reloading the shotgun or crossbow, press the fire button (default is Z). Your character will immediately stop reloading and put the weapon at the ready position. When there are no opponents or enemies around, you can press the reload button and finish the reload later - when it is safer. This very helpful in the multi-player "combat simulator" mode, as even the CPU takes too much time reloading such weapons.

Hint: Quick shot:Hold Z, then hold A during game play. You will not be shooting, and when you press A(especially with a pistol), it will fire a few shoots. With a pistol it seems to be easier to shoot faster.

Hint: Quick shot with the secondary on your weapon:The following trick allows a quick shot with the secondary on your weapon (or primary if you are in secondary mode). Hold B and press Z. It is almost exactly like rotating through weapons backwards with A and Z, but you substitute B for A. This works well with the shotgun to get a quick double blast at point blank range, or to quickly throw your dragon as a proximity mine.

Hint: Quick weapon mode switch:To switch your weapon mode more quickly, hold A button until the quick weapon switch menu appears, then hold Z button and another quick menu will appear. The new menu will only show the weapon's different modes.

Hint: Faster Farsight target locator:Instead of taking the time to hold B while using the Farsight to locate a target, you can just scope in and hold C-Left or C-Right. This is better, since it does not move as much as the target locator.

Hint: Retrieve Sentry Gun:Anytime time you throw a Laptop Gun as a Sentry Gun, you can get it back by putting all guns away and pressing B while facing it. You will also get all the ammunition back was not spent shooting at enemies.

Hint: Slower Slayer Fly-By-Wire Rocket:When you have the Slayer, change it to the secondary mode. When you fire the rocket hold Rto make it go slower for easier turns and maneuvering. Release the button to send it speeding towards your opponent/enemy.

Hint: Slayer controls:Press Z to detonate the rocket. You can also slow it down by pressing B.

Hint: Easy kills with the Slayer:When you have your opponent in your sights and you cannot turn the fly-by-wire missile around in time, press Z again to self-destruct it.

Hint: Counter Slayers:Use the following trick when you have an opponent in multi-player mode who is using Slayer missiles to hunt you down, making it impossible for you to get close to him or her. Get an explosive weapon (preferably the SuperDragon in grenade mode). Just as you see the missile flying towards you, trigger the explosive. Make sure it is not too close or you will get caught in the blast. If aimed correctly, the flames should catch the missile and it will explode.

Hint: Unlimited Mauler rounds:This trick requires double Mauler (one in each hand). Immediately when you have it out, shoot and put it away at the same time. The game will put them away and when you pull them out again, you will not need to charge them and will have unlimited ammo.

Hint: X-Ray Camspy:You can use the X-Ray vision while in your camspy. Activate X-Ray vision, then go into your Camspy. Note: The Camspy must be in your weapon selection inventory.

Hint: Detonate Remote mines easy:Press A + B to detonate a remote mine without changing the remote mines function.

Hint: Shoot through platforms:If there are platforms with holes in them you can shoot enemies through the platform undetected.

Hint: Rocket flares:Enable the "Unlimited ammunition no reloads" and "Invincibility" cheats. Get a rocket launcher, fire a round on the ground, hold C-Down (until looking then press C-Up + hold Z). While holding Z, you can kill people in your way. Note: You can still look at where you are going by holding C-Up + Z.

Hint: Disarm option:Leaving disarm on indefinitely is not always a good idea, as disarming an opponent with a weapon does no damage. If you are low on health or need to take an opponent out quickly, punch them instead.

Hint: Easy knockouts:This trick allows you to easily incapacitate enemies. Sneak up on an enemy undetected, and instead of shooting them and wasting ammunition, pistol-whip or punch them for an easy "kill".

Hint: Earn cheats easier:Turn on fast movement to make earning cheats easier.

Hint: Easy medals in combat simulator:To earn medals for your record in the combat simulator (accuracy, head shot, kill master, and survivor) log in your record for player one. Leave player two as it is already set. Shoot player two in the head each time until you have about ten kills. Quit and you should have all four medals.

Load your character and start a second character. Then, set the options for a level you know well and is rather small. Set the game for one kill wins with an accurate weapon, such as the Falcon. When you start the game, get the Falcon, find the second character, and shoot them in the head. This is much faster than killing the other player many times. You get all four medals every time if you only use the one bullet to kill the second character.

Enter the combat simulator, and select "Advanced Setup". Make a character just for you to kill. Put all the limits to full (endless battle), your handicap 10%, and the character you made to 1000%. Make all the weapons Farsights. Play in any level, but do not change the default settings except for those previously specified. Start the game with you and the recently created character. Go to the nearest Farsight, put it on the secondary function, and shoot the recently created character only once, then quit. Make sure that you hit him on the first shot or you will not get all the medals. This can be done faster if you point the Farsight at him by using your radar, and then aiming after it is pointing at him. This will earn all four medals in about ten seconds. Keep repeating this to increase your rank. Additionally, if you do this for a while it will increase your accuracy up to 99.5%-100%.

Set four simulants to dark sims. Press A on them and you will be prompted to change the type. Change the type to fist sim or judge sim. These sims do not attack with weapons. The judge sim disarms you only and does not attack. Using these sims, you can gain ranks much faster.

Go to advanced setup in the combat simulator. Choose a two player game, set all weapons to Farsight, and the arena to Felicity. Put a perfect sim on player two's team. Do not put yourself on player two's team. Start the game over until you are in the small room at the end of the hall. Quickly take player two's controller, then hold A and press Z(2). Move the cursor to "Protect". When the sim gets to player two's screen, hold A and press Z(2), then put it on hold. Now with player 1, get a Farsight and shoot the perfect sim in the head repeatedly. It may appear as if is going to enter the room and kill you, but it will not.

Hint: More simulants:To get more Simulant buddies in co-operative mode, complete it on different difficulty settings. If co-op is completed under the Agent difficulty setting, then two simulants will accompany you. If it is completed under the Secret Agent setting, three will accompany you. And if it is completed under the Perfect Agent setting, four will be able to accompany you.

Hint: Defeating simulants:Simulants do not know how to detonate controlled mines. Switch all your weapons to them and set a group of dark simulants.

Hint: Command simulants:Use the following trick when you have simulants on your team. . Make sure no enemy simulants are near. Then, hold A and press Z to display your gun functions. Press Z to display a simulant's name and weapon at the top of the screen. Below are commands such as "Protect", "Defend", "Normal", etc. Use the Analog-stick to choose a command and release Z. Complete the process by pressing Z once again.

Hint: Suicidal simulants:In the combat simulator, choose any scenario and choose the G5 building as the arena. Once the game has begun, go where the blackness is over the ramps and fall. As you are falling, program your simulants to hold in place. This means that all simulants will be standing in your place, but they will not be standing because they are committing suicide. Once you have died then respawn, go where you died. Notice that your simulants are killing themselves. After about ten or fifteen minutes, press Start. Go to your scores and deaths. Choose another simulant and look at the top bar and notice the suicide count.

Hint: Laptop gun tricks:To get an Easy gold at the target range with the Laptop Gun, hold B and fire it at the wall behind you. It will turn to a sentry and stick. Just duck down, and get out of the way. It will get you 100% accuracy, and a gold every time.

If an enemy has a sentry gun active (Laptop Gun in its second mode), and you cannot seem to destroy it, just use an XR-20 Farsight with the Target Locator off. Stand in a nearby room, find it with R and C-Up and C-Down, then take it out with one shot.

Once the gun has been deployed as a sentry, you can pick it up and use it again by getting close, centering it on your screen, and pressing B. This is useful for changing its position or reloading it with ammunition (a good idea, as it wastes quite a bit). While in the combat simulator, you cannot pick up a sentry that someone else has laid. You can also use this in single player mode to kill people that are just around the corner -- then get your gun and leftover ammo back for later fights.

Enable the "Laptop gun" and "Unlimited ammo no reloads" cheats. During any level, throw the laptop gun at a heavy crowd of enemies and allow it to flatten them. Then, put the gun away and walk up to the sentry gun. Face it and press B. If done correctly, you will pick up the laptop gun. You can do this as many times as needed easily complete a level.

Hint: Exploding elevator:Enable the "All weapons" code. To make the elevator explode in the first three levels, place a couple of timed mines on the doors just before you get in. If timed correctly, you can make them explode immediately after Joanna pushes the elevator button to make it look like a bomb. You can also do this on other levels.

Hint: See weapons from GoldenEye 007:Go to the hallway where the target practice is in the Carrington Institute (select Carrington Institute on the select mode screen). You can see weapons from GoldenEye 007 (Klob, KF7 Solviet, RCP-90, AR 33 Assault Rifle, etc.)

Hint: X-Ray mode ending:Collect the X-Ray Scanner during game play, then activate it just before the end of the level. The ending sequence will play in X-Ray mode.

Hint: Night Vision ending:Turn on your night vision goggles immediately before you complete a level.

Hint: Cloaked ending:Earn the cloak and infinite ammunition cheat to be able to complete a level while cloaked.

Hint: Unlimited cloak on the RCP-120:Get a RCP-120 and set it to the cloak function. Hold Z and your ammo should go down. However, when it reaches 0 while Z is held, you will not reload until you release the button.

Hint: Visible cloaked opponents:When any opponent has activated their cloaking device, you can still be able to see them as a blur. Note: You cannot see them from far away, only at close range.

This trick works on single player and multi-player mode. Select the CHP150 and any other desired weapons, then start the game. Hold B during game play until it switches to the target locator. Hold Aim until it locks onto the player. When the player cloaks, you will still have the target locator on him -- you will see the little box around the character, but you will not see him.

Hint: Stop Combat Boost slow motion:When you use the Combat Boost on any level (Single, Counter, Co-op, etc.) and it gets annoying, go to the secondary form of it that says "Revert" and press Z. The annoying slow motion will stop.

Hint: Shoot at other people at firing range:Go to the firing range in the Carrington Institute. After you enter the actual firing range part, turn around and make sure the door is open. Keep moving forward until you block the door from closing. If done correctly, you will still be able to choose a weapon and use it. You can shoot at the people in the other room, but cannot hit or kill them. You can also use explosives and blow up the lights - the room will be black until the game is restarted.

In the Institute, go down to the hanger, get the hover-crate, and bring it up to the firing range. You can place it anywhere in the doorway, as long as you can get by. It is recommended that it be placed right where the door goes into the wall. Once the crate is in place, go into the range and choose any gun or weapon. The simulation will start, but the door will not be able to close. Walk up to the open doorway and start shooting. If you use explosives the crate may blow up, so save those for last.

Use the Farsight x20 in the firing range to shoot the guns in the cases and the attendants. Note: You cannot kill the attendants.

Go to the firing range in Carrington Institute. Go to the door leading to the range. Position yourself so that you are halfway in and halfway out. Press Start. If you are positioned correctly, you should be able to choose a weapon but block the door from closing. You can shoot the man standing there or the man at the computer. Also select the crossbow or the combat knife (second function) - you can throw them at the man standing in front of the door and they will stick in him.

Go the hovercrate from the hangar and use it to prop open the glass door to the firing range. Select remote mines as your weapon in the firing range. Throw a remote mine onto Foster and make sure it sticks. Walk around the crate and exit the glass door. Do not abort. Go back into the firing range and choose a weapon. The remote mine should still be on Foster. Shoot it and blow him up.

Hint: Human pincushion at firing range:The training man at the firing range at the Carrington Institute can be used as a human pincushion. Use poison dipped throwing knifes to throw out of the room. Just move to the position to shoot out of the range, use throwing knifes on him, and he will be a pincushion. You can also throw mines or shoot the crossbow at him.

Unlock the Farsight and Combat Knives in the Shooting Range. Then, go in the hangar and grab the floating box by pressing B next to it. Drag it to the Shooting Range and walk in the targeting range with the box, backward in the glass door after you open it. Drop the box in the doorway so it cannot close. Select the combat knives stick some knives in the man's forehead in front of you. Throw about 20 knives in the box. Abort the training and then quickly run to your boss' office. Put the box next to him. Run back to the Shooting Range and take out the Farsight. Look up to your upper left. You will see your boss and the box that is next to him. Shoot the box. It should take one hit. Abort the training and go to the device training room. Select the cloaking device. Run through the back room maze to your boss' office. Make sure you cloak before you pass the camera so you can get to his office. Pick up the knives and quickly throw them at him. After you hear him say "Your training is now complete" you will be put back in the device training room. Go back to the Boss' office to see what you did to him.

Hint: Farsight at firing range:Use the Farsight at the firing range and aim through the walls. You can blow up chairs and computers in other rooms of the Carrington Institute. You can also shoot the classic 007 weapons in the hallway outside the firing range.

Hint: Sparking light at firing range:Use the hovercrate in the hangar to keep the weapons training room door. Throw some sort of grenade (such as the Dragon's secondary fire/bomb mode) out into the first room. Leave the weapons area. In the room that goes to the weapons training room (with the scientists), one of the lights should be disabled and sparking wildly.

Hint: Easy firing range golds:Select the Laptop Gun and put it on bronze. Hold B, turn around, and pull the trigger. Immediately press Start, before Joanna can throw the gun, and abort. Then quickly pressStart again and select any other weapon from the menu. Set it on Gold (or whatever), and as soon as the target range starts, the sentry gun will get thrown out and stuck to the wall. This trick can get you most of the golds.

Select the Laptop Gun. Change the form of the gun and stick it on the wall behind you. PressStart and abort before it hits the wall. Press Start again before it hits the wall and select the gun you want to complete. Your laptop gun should shoot the targets without you wasting a bullet. Note: This does not work with the certain guns where you have to get all bullseyes.

Hint: Explore the Carrington Institute:Go to the firing range in Carrington Institute. Go to the door leading to the range. Position yourself so that you are halfway in and halfway out. Press Start. If you are positioned correctly, you should be able to choose a weapon but block the door from closing. Select the Slayer and use its second function (fly-by-wire rocket). You can shoot the rocket and fly it out the door and almost anywhere in the Carrington Institute. You can fly it all the way down to the maze of hallways, but no further because the doors are closed. Another fun thing to do is to see how long it takes you to fly it to any given place. Then try to beat that time. You can also do flips and flip the rocket upside down.

Take the floating box from the hangar and bring it to the device training door. Leave it between the door so it will not shut, then go do the Camspy training. You can go out of the door and go anywhere in the Carrington Institute.

Hint: Death sentence:Throw a mine (preferably a proximity or time mine as they automatically go off) on an opponent. The mine will stick on them, and in a few seconds, blow them up for an easy kill.

Hint: Team motivation:Enter game play and hold A to display the quick menu. Press Z(2) and you can control who attacks, and who stays with you. There is, although, a few choices that may seem strange.

Normal: Simulant will killing everything that moves on their random path.
Hold: Simulant will attack nearby enemies while holding their ground.
Defend: Simulant will chase down any nearby enemies.
Attack: Simulant stalks the person you tell it to attack.
Follow: Simulant follows you, but chases after nearby enemies.
Protect: Simulant stays close to you and attacks nearby enemies.

Hint: Daniel Carrington comments:When in the Institute, do not go into the target range, and kneel all the way down. Start moving around in front of Daniel Carrington and he will say things such as "Stop it Joanna, that worries me!".

In the Carrington Villa level on solo mode, shoot out all the bottles on the shelves in the wine cellar at the end of the level. Once they are all destroyed, you will hear Carrington say, "Act your age, Joanna."

Hint: Hear female guard voices:Start any level under the cooperative missions with Velvet Dark as your partner under CPU control. Every once and a while she will shoot at guards and say female guard quotes, just like Cassandra's bodyguards.

Hint: Kill Elvis, Mario-style:Go to the Skeder spaceship and find Elvis. When he wants you to go to the elevator, go there. You should arrive on the top floor first. Look where Elvis is then jump on him and he should die.

Hint: Perfect Elvis setup:Unlock the following cheats: Play as Elvis, Phoenix, and Farsight. Enable these codes and it will seem as if you are actually playing as Elvis in the missions. For a Maian invasion, complete co-op story mode under the Special Agent difficulty setting. This will allow you to have three Simulants in Agent mode and two Simulants in Special Agent mode. Unlock the Alien cheat. You can now have Elvis and two to three Maians with RCP-120s invading any level you wish to play in.

Hint: Cripple enemy:Shoot an opponent once, anywhere except in the heart.

Hint: Ride the hover bike:Walk up next to a hover bike in the Area 51 missions and tap B(2). Joanna will immediately jump on it.

Hint: Fun with mines:Enable the "Cloaking Device", the "All Guns In Solo", and "Unlimited Ammunition" cheats. Choose any level, but the first level works best. When the level begins wear your cloaking device and set Remote Mines as weapons. Place the mines on people's feet, stomachs, or heads, then detonate them. Also try placing a mine on a person's stomach, then punch them and detonate.

Hint: Mutate heads:If you have an explosive weapon or a gun such as the Phoenix in secondary mode, either shoot or throw the explosive at the enemy's head. If it is a remote mine, detonate it. When the smoke clears, the guard's head should appear to be mutated. This may not work the first time. This trick will not work with the Dragon Proximity mine.

Hint: Higher head shot count:Enable the "Slow Motion" cheat in the Combat Simulator. Set the arena to any desired location. Set all weapons to any pistol, preferably Falcon 2s and enable one hit kills. Load your player and one Meat Sim. The Meat Sim should have Mr. Blonde's body and an Alien head. When you find the Simulant, shoot it once in the body to kill it then shoot the rest of the magazine into its head while its falling slowly to the ground. This will give you more head shots but will not give you any head shot awards.

When fighting an enemy, punch him until he is unconscious. Although he is on the ground, this does not count as a kill because he is not dead yet. Take out one of your guns, aim it down at his head, and fire. This will now count as a head shot kill on the scoreboard that you get at the end of the level, which is the highest killing score you can get.

Hint: Get locked in closet:Select co-operative mode then go to the Air Force One Antiterrorism level. Have both players go to the room with the ramp that leads to the President's floor. There will be two guards standing there (one might not be there yet -- he will walk in, so wait there for him). Knock them out and they will drop two key cards for the closet doors on the side of the room. Have each player open their closets. (Closets contain the level's secret weapon -- Double Cyclones). Then, run across to the other player's closet and enter before it closes. Since you have switched.

Hint: Put enemy through table:Note: You need an explosive weapon for this trick. To put an enemy guard through a table, disarm him and make sure he puts his hands up or stands still. If a table is available, move it either in front or behind him, depending on where the table is located. When the table is in place, get your explosive weapon and either fire it or detonate it near his feet. This will cause him to fly into the table. The explosion will break the table and the enemy will land on it simutaneously, making it appear as if he went through. Note: The guard may sometimes fly over the table or the table may break before he hits it.

Hint: Make Air Force One crash:On the solo missions, select "Air Force One". Complete objective one, which is to locate the President. When the UFO attaches to Air Force One, kill the President, then detach the UFO. Afterwards, you should hear some talking and the plane going down.

Hint: dataDyne symbol:The dataDyne symbol appears to be missing a piece. Look at the symbol for the Carrington Institute -- it is the missing piece. Each of the four pieces of the dataDyne Symbol corresponds to a person -- . Mr. Blonde, Cassandra De Vries, Trent Easton, and finally Daniel Carrington.

Hidden cheese locations

Hidden cheese:Every single player mission has a piece of cheese hidden in a location that has nothing to do with your mission objectives.

dataDyne Central: Defection, dataDyne Central: Extraction, and Mr. Blonde's Revenge Mr. Blonde's Revenge:To find the cheese in the first level, go into the first room inside the building. Look at the computer monitor you work with under the Special Agent and Perfect Agent difficulty setting, and blow up the column to the right of it with explosives (such as the Rocket Launcher). Climb down the ladder and the piece of Swiss cheese is sitting in the vent.

In dataDyne Central: Defection and Extraction and Mr. Blonde's Revenge, there is a piece of cheese hidden in the vents in the hidden room in Cassandra's office.

In the dataDyne Central: Defection and Mr. Blonde's Revenge level, the cheese can be found by blowing open the vent shaft to the right of the first computer screen object hanging on the wall in the red light. Alternately, go into Cassandra's office and move along the right wall. Blow a hole in the wall at the corner. In the third level, though the same area, you cannot blow up the cylindrical wall to get to it.

Area 51: Rescue, Area 51:Escape, Maian SOS:There is a piece of cheese at the end of the vents that drop you into the showers.

Skedar Ruins and War!:There is a piece of cheese in the "S" shaped crack in the wall by the second shield in the level. Go down the small alley by the entrance to the Skedar base to the tunnel where the shield is located. Look through the crack and you will see the cheese.

Air Base: Espionage:the is a piece of cheese outside. You must use the Horizon Scanner or Sniper Rifle. After you go through the cave, turn right into the small ledge. Use your scope of your snipers rifle or Horizon Scanner to look down at the water below. There is a piece of cheese in the corner .

Air Force One: Anti-Terrorism :Face away from where the President's escape pod is contained. Look to the right of the bulbous object towards the wall on your right. This particular piece of cheese is not very detailed.

There is a piece of cheese hidden in the machinery by the Escape Pod where the president goes.

Area 51: Rescue level:Note: This may not work under all difficulty levels, but will work under Special Agent. After going up the first elevator, go right (the wrong way). Get close to the man before shooting him, and someone should open the locked door from the other side. Go up onto the catwalk and walk across one of the bridges into a hole. Look to the end of it to see the cheese. Going down the hole will place you in the showers.

Attack Ship: Covert Assault:There is a piece hidden in the floor. Turn right after you emerge from the first elevator at the beginning. Through the door on the right, where the Skedar come through, is a blue hole in the ground. In a corner of the hole is a piece of cheese.

Carrington Institute: Defense:There is a piece of cheese wedged up above the door that the Skedar broke open. Just go through the door and up the ramp. Turn around and use your AR34 to see the cheese.

Carrington Institute:Note: It is easier to find this piece of cheese when you are not playing the solo mission in the Carrington Institute, so you do not need all guns. Go down to where the jerk is and take the hover crate up the ramp. Hold the door to the target range area open with it. Stand just in the practice area so the door will hit you when it tries to close. Press Start, select Slayer, and put it on Bronze, which gives the most time. Fly it in its secondary mode all of the way down the ramp. When you get out in the open, go up and to the right. The cheese is sitting above the door that is broken open in the solo missions.

Carrington Villa:Go to the beer bottle location, then go to the Carrington door but do not open it. Turn around then you will see two "beer bottles". Go to the hallway with the first "beer bottle" that you saw. Move against the wall, then stand back. Then at the top, if you can see the middle, is be a piece of cheese.

In the Carrington Villa, there is a piece of cheese on top of the 4th wine shelf in the basement.

Chicago: Stealth:Enter the building the limo is parked besides and go down the ramp. Do not kill the men there -- just disarm them and let them run into the locked area which also allows you in. Find the bathroom and look in the toilets in the stalls. The left one contains the cheese.

In Chicago: Stealth the is a piece of cheese in one of the toilets in the "Pond Punk" bathrooms.

dataDyne Research: Investigation:Go to the experiment location to finish an objective under the Perfect Agent (or Special Agent) difficulty setting. Then, go through the other door in the room. After one door you should see another door - go through that door but stay still. Shoot the scientist at that location, then go straight ahead to find a glass floor. Look around that floor to find the cheese.

There has a piece of cheese hidden underneath a glass floor in the third lab where the rude scientist is supposed to turn of the experiments.

Deep Sea: Nullify Threat:There is a piece of cheese in the water. Go through the first doors at the beginning of the level and turn left. With a scope, look out through the window at the ocean floor. A piece of cheese is on the ground.

Go to the door that leads to the second room when you first start the level. Open the door, then look left in the first window. Search carefully and if you see something yellow, use sniper rifle to examine it closer.

G5 Building: Reconnaissance:Go down to where you work with the computer under the Perfect Agent difficulty setting. Look in the vent to see the cheese.

In the G5 Building there is a piece in a vent by the computer mainframes in the room where you shut down the Damping Field Generator.

Skedar Ruins:Go until you get to the Skedar that have slayers. Take one, then return to the area where you blow open the wall. Facing the way you do when you first enter the area, go right. In that area, there is a small S-shaped hole in the wall. Shoot the Slayer Rocket through in its secondary mode -- look down at the floor to find the cheese.

On Skedar Ruins, where you blow up the wall, is a Skedar that attacks you. Turn left from the area he appears from and keep going down that path, killing the Skedar. When you get to the end, there will be a crack in the ground. Do not worry, you cannot fall through. Drop down and kill the Skedar and get the shield. Then, turn around and look through the S-shaped crack in the wall. Having a gun with a scope (such as the Falcon 2 or the Sniper Rifle) will help. Look slightly down and to the left through the crack to find the cheese. You may have to adjust yourself a bit before you can see it.

Game glitches

Disappearing Laptop Gun:Go to the firing range. Position yourself so you can block the door from closing. Select the Laptop Gun on the Silver or Gold setting and begin. Make it where you can throw out the gun so it lands on the wall. Wait until time runs out and it will disappear.

Disappearing GoldenEye 007 guns:When you start in the room and you are on the computer, get off of that screen then leave the room. Turn a left and go in the elevator. Go down and the take a left. Enter the room to the left and there will be doors to the right. Enter them. This is followed by a hallway filled with guns from GoldenEye 007. Go in the Shooting Range and use the magnum. Aim at the guns and shoot them. They will fall off at times will disappear.

Disappearing guns:Go to the firing range and select the Farsight Bronze Medal. Aim towards a case and shoot. When done, the guns will not be there.

Disappearing Carrington Institute:Pick up the hovercrate from the hangar in the Carrington Institute. Bring the crate up to the room next to the device training room. Place the hovercrate in the room's doorway, so that it prevents the door from closing. Exit the room and enter the device training room. Approach the computer with the man sitting nearby, press B and select the Camspy. Once your mission with the Camspy has begun, pick up your Camspy from the table. As you approach the table, a secret passage should open. Launch your Camspy through the opening. Once it is launched and you are in control of it, move forward then left. Maneuver the Camspy into the vent near the floor. Once your Camspy is in the vent, send it forward until it reaches the second left turn. Once you have turned left, follow the vent all the way until you reach a red exit. Make the Camspy approach the red exit. Once the Camspy has reached the exit, pressB (as if opening a door with a human). The door will open. Maneuver the Camspy out of the vents, and you should be in the room next to the device training room. This is the room where you blocked the door with the hovercrate. Maneuver your Camspy to the wall nearest to the device training room (with the big opening at the top) until it hits the wall and can go no further. Press A to control Joanna. Hold A to bring up your weapon menu. Select Camspy and you should be controlling your Camspy once again. Turn the Camspy around and it will appear as if part of the Carington Institute has disappeared. To make the Institute reappear, back away from what is left of it.

Disappearing Velvet:Start the War mission in cooperative mode with as many Simulants as possible. Go up to the bridge that you activate on the last mission (this can also be done there, but this makes it faster). Have your Simulants stand on it, and push them off. They will fall straight down and disappear, as well as die. However, as you can see, there is still a bottom to that ravine.

Rocket launcher secondary mode:There is a glitch with the rocket launcher's secondary fire mode. Stand still as it is coming at you, then strafe to the side as it gets close. It will begin to orbit you. Shoot it out of the air and step backwards to avoid the blast. Using an automatic weapon is recommended.

No Slayer:Start the War!!! level with the "All Weapons" cheat. Walk directly up to the second Skedar King and kill him. A message stating that you have received a Slayer will appear. However, you will not actually get it.

ECM mine:On level 1, throw an ECM mine on an enemy and shoot it off. They will think it is theirs, and either surrender or try to shoot you with it. However, it just bleeps and does nothing.

Floating spinning knives and arrows:Enable the "All Weapons" and "Unlimited Ammunition" cheats. Enter the Air Base mission under the Agent difficulty setting. Enter the base and get rid of the guards and the woman. Then, look straight up. There should be a window facing the sky. Shoot arrows and throw some knives at it. Then, switch to your sniper rifle and shoot each of them off. When they fall, some of them will not touch the ground. Instead, they will float and spin indefinitely. To get rid of them, just do not look at them or pick them up.

Infinite explosion:Start a game in the combat simulator with all the Simulants in your team. Have all the weapons set to proximity mines. Choose the scenario as Capture The Case, and the level as Felicity. Start a game and play until the bathroom is your base. Set all your Simulants to "Save Case", then wait until they are all gathered around it. Next, place two or three mines in the little room between the bathroom and the stairs (where they are respawned when they are killed). Do this quickly or the mines will detect the others and explode. Then, place a mine on one of your Simulants and wait until it explodes. Make sure that you are far away. This will kill them all, and when they are respawned in the little room, the mines will explode and there will be an infinite explosion created there. This can kill as many as 2,000 of them in about twenty minutes. This is an easy way to gain points. However, make sure you do not die due to any of the explosions, as you will also be involved in it, and the game will not give you a chance to get out unless reset or power off the Nintendo 64 or wait until the game ends. Note: Sometimes it will die off if you go to a place far away from it.

Invisible guns in target practice:Get a gun that shoots through walls. Aim at the guns on the wall and shoot them. When you leave target practice the guns on the wall will be gone.

Invincible assassin:Enable the "Laptop Gun" code. At the end of the Maian SOS level, before you activate the signal, throw down the Laptop Gun. In the animation a man will come up behind Elvis getting shot by the Laptop Gun, but not getting hurt at all. This may also work on different levels.

Invisible Dr.Carrol:Go to the Datadyne Extraction level. To do this you need to have the Dragon gun from Cassandra's office. To get it, kill everyone in the floor with no lights without being seen. A guard on the first floor the elevator takes you to drops the key to her office. Go in her office and get the grenade from her desk. Throw the grenade at the right corner of her office. Go in the hole it creates and get the Dragon gun. Complete all your objectives except "Rendezvous At Helipad". Go up to the helipad, but not on it. Throw the Dragon in secondary function in the far right corner of the helipad. Slowly and carefully sidestep onto the helipad and start the ending sequence without the gun blowing up. The gun explodes in the sequence, killing Dr. Carrol. However you do not fail anything and all the same mechanical noises still happen. Joanna still puts out her hand for Dr. Carrol to fold up on it, but he is not there.

Invisible Joanna:Play the Carrington Institute: Defense level and complete all the objectives. When Carrington tells you to get to the last dropship, pull out your RCP and set it on secondary mode. Go up the stairs and go in the door. You will see the gun firing, but not Joanna.

Floating items:Find the location in the Grid level where there is glass in the main room up top. Go upstairs and on to the glass. Place a sentry gun on the glass. Then, shoot the glass all around it. The sentry will float in mid-air, making it easy to get people on both bottom and top.

This can also be done with other items, such as a Dragon.

Use the following trick to see floating ammo boxes and guns in solo mode. Enable the "Unlimited ammo" code, and optionally the "No reloads" and "Invincibility" codes. Locate the ammo boxes on the desks in the upper part of the Mr. Blonde's Revenge level. Since you have unlimited ammunition enabled, you will not be able to pick them up. Push the desk away from the woman, who cannot see you because your cloak is also unlimited. She will still be typing and the ammo box will be floating in mid air. You can do this to almost every table -- some will stay on the table when you push it. There is a Falcon 2 on the desk in one of the rooms. When you move it, the gun will float. If you shoot the gun in mid-air, it will separate into two guns.

Shoot the ammo box until it pops up in mid air, then grab it by running into it. When the box reappears it will be floating where you picked up the first box.

Enable the "All guns in solo" and "Unlimited ammo no reloads" codes. Play the Carrington Institute: Defense level and go to the elevator. Throw combat knifes at the glass. The knifes will be float while spinning.

This glitch occurs in the Defection level near where the elevator's sides have bullet-proof glass. Throw a combat knife or shoot a crossbow arrow at one of the sides. They will continuously spin or be suspended for a long period of time.

Floating knives in Attack Ship: Covert Assault:Select a solo, co-operative or counter-operative mission on the level. Go to the navigation room on the second level of the ship. The holograms on top of the navigation console are treated as solid objects by the game. Take your combat knife and throw it at one of the holographic lines and it will embed itself in it and float along with the hologram. Activate the "Unlimited ammo" cheat before you begin the level to make things more interesting. Try shooting out the knives to sharpen your aim.

Spinning knife:Play the Carrington Institute: Defense level under any difficulty setting and go upstairs. Enable the "All guns" cheat. Go to any of the elevators and notice the glass on each side of the landing. Take a knife on poison knife or a crossbow and shoot the glass. Note: This work better with the "Unlimited ammo" cheat. When you throw this knife, it should be spinning for quite awhile.

Upside down combat knives:To get the slashing knife upside down, hold B to turn it to "poison throwing knife". Then, holdZ until they are above your head. Do not release the button yet. While they are above you, hold B to turn it back to "knife slash" and throw the knives. They will be upside down in your hands. Note: To return the knives to normal, flip them to "poison throwing knife" position and back again.

Changed knife action:In multi-player mode, have double combat knives and set them to throw. Hold Z while changing weapon modes. Release Z, and if done correctly, it should look like you have the knives on throw, but when you press Z, they will slash.

Pipes level:On the elevator, have one player in the corner next to the two walls. Then, have the other player on the ledge where the fourth weapon slot would be. When the elevator goes down, have the player on the ledge fall on top of the other player. When you do this, both of you will keep going slowly up in the air past where the elevator would normally take you. When this happens you really cannot move. When you get very high in the air, everything will glitch. To get out of this, just kill one of the floating people. It is best to have Joanna on the bottom and Elvis on top.

The Duel level: Non-stop walking:Play the level under the Special Agent or higher difficulty setting. Kill the Datadyne guard and bring up your aiming sight before it says Special Agent. Leave it up until your back is to Jonathan, then you will not walk forward. If you start to reload before your back is to Jonathan and you start walking before you finish reloading, you will not stop walking.

No feet:Stand in a corner and look straight down. Joanna Dark does not have legs.

Stretchy face:In any solo mission, knock somebody out with your fists. Then, use an explosive device on them. If their body was darkened, look at their face after the smoke has cleared. It should look distorted.

Jumping on man's head:On the first level when you are on top of the roof, jump off to the side. If timed correctly, you should jump on the man's head without him knowing you are there.

Living dead:When you knock someone out, they will fall down. Shoot them in the head while they are down. Sometimes they will jump up and then fall down again. Note: This works best on the Skedar, when shooting them in the eye.

Hypnotized enemy:Knock an enemy unconscious, and then shoot them somewhere without killing them quickly before they hit the ground. They should stand perfectly still in a hypnotized manner until you shoot them, breaking the curse and killing them. This glitch works easily using the quick pistol whip with the Falcon pistol.

Strange scientist:Enable the "Psychosis gun" or "All guns" cheats. Enter the Pelagic 2 mission under the Perfect Agent difficulty setting. Go up to one of the doors of the rooms where the scientists with the research items are located. Do not open it. Look through the window and wait for them to get into your line of fire. Then, shoot them with your Psychosis gun. After that, they will start doing strange things, such as bending down as if they were going to pick something up and more. If you enter, they will run away from you as usual.

Flying temple:In the Temple level in multi player mode, go to the larger open area in the lower area (not one with hole in ceiling). Go on the ramp that goes up onto the walkway above, where you can still see down into the room. Move back and forth against the wall and you will "fall out" of the temple and watch it fly away as you die.

Fall out of the Air Base level:Make sure you have the disguise on. Go behind the desk where the woman says "Okay, you know the way from here". Go behind the desk in front of the woman and crouch down to the smallest position Jo can get into. Then, activate the Drugspy. As soon as it goes on, it will fall through the ground. All you will be able see is the two mountains and the sun as it drops.

Explore Area 51 Infiltration:Play the Area 51 Infiltration level with the "Invincible", "All guns", "Unlimited ammunition", "Cloaking device" and "Perfect Dark" cheats enabled. Set the enemy health to 100% and start the level. Play through normally until you have to place the comms rider on the antenna array. Place the comms rider on the antenna, then cloak. Take out the Psychosis gun, and when the guards exit the door, tag them all. You now have your own team of Simulants to finish the level with. Complete the level as usual. Enter the hangar and let your new team gun down their former friends. When you get to the man who lays down on the floor, your team will shoot him, and he will open the locked door behind him. This will allow access to part of the next level. In the stores, you will find Jonathan and that man he shoots in the intermission between to the very end of the level. This hangar's doors will get opened by the guards blocking the way. You will see the night sky. Do not get curious and walk through it unless you want to die.

Jonathan stuck with weapons in Area 51 level:Enable the "All weapons" and "Cloaking" cheats. Go to the first Area 51 level and go down the lift into the first hanger. Across the hanger is a door which is locked and a guard standing next to it. Approach the guard while cloaked and go behind him. Fire one shot over his shoulder but do not actually hit him. After awhile he will stand around and open the locked door. Go inside to find Jonathan on the lower floor, He will be invincible for the time being and will not recognize you. Fire as many arrows and knives into him as possible. Take your Farsight and use the target locator to find a guard. Shoot at the guard but do not hit him. He will run after you and open another door. Run out the door and complete the regular mission. At the end, Jonathan will still have all the arrows and knives in him during the ending sequence.

Get inside pipe in Ravine level:On the Ravine multi-player level, there is a yellow pipe. Stand on the pipe and face either towards the elevator or the vertical pipe. Face the elevator. Press C-Left until you are just barely off the edge, then quickly press C-Right. If done correctly, you will not die. However, you will not be able to see the pipe -- you will be inside it and others can only see your feet. If you crouch, you will be invisible unless your opponent has an X-Ray Scan or Farsight. You can still die, but only with explosives or the Farsight. Note: This may take some time to master.

Be referred to as a woman:In the Mr. Blonde's Revenge level, if you go up in front an enemy, he or she may say "get her" when you are a man.

Kill Elvis on lift:On Skedar Assault Ship, when Elvis says "You take this lift, I'll take the other one", get in the lift. Once at the top, jump down into Elvis' lift. It will say mission failed and Elvis will be dead.

Deploy the camspy just outside where it has to go, but leave it there. Place the door decoder where it goes, then immediately switch to the Camspy and fly it in the room. Watch the entire cinema. By the time it is done, the safe door will be completely open, and the wait time will not be added to your mission time.

When you begin, you will be in a room with two cloaked guards. Finish them quickly and take the last guard's keycard. Go through the door and kill the guard that should be waiting for you outside. Go into the next garage bay and the lights will go out when you reach the glass dividers. The four guards in there need to be eliminated, and you will need the last guard's keycard. Eliminate the next four guards quickly so they cannot hit the alarm. Go to where you need to launch the Camspy for Objective 1. Go down as far as you can and get into the overhead duct work. Just before you jump down and surprise the guards that are waiting, launch the Camspy but do not send it in yet. Jump down and kill the guards before they hit the alarm and go to where the safe is located. When you put the door decoder on the machine, immediately switch to the Camspy and send it in. You will hear a voice saying "Intruder alert, all security to the vault" while the intermission sequence starts. Watch the entire sequence and when it is over the vault will be unlocked and open. Grab Dr. Caroll and leave the room, blasting through the guards. You will then hear Daniel Carrington tell you to stand back to blast open the door. Go through to end the level.

When you are low to the ground, hold R +C-Down to hide your screen. Try to duck even lower when you are as low as you can get. Turn off radar to add to the fun.

Hint: Air Base Espionage: Twin DY357s:Take care of both NSA lackeys (one at the escalator and the other at the freight elevator) and the last one at the station before subverting security, you will get two magnums.

Hint: Air Base Espionage: Help from guard:Go to the security terminal with your phoenix set on explosive shells. Get in a position so that you can turn off the security console, but do not turn it off. Take out your phoenix, shut down the security, and kill the black guard before he kills the Falcon 2 guard. Note: The guard has an aggressive personality and will run after guards from far away.

Hint: Air Force One Anti-Terrorism: Double Cyclones:Two guards at the base of the staircase have keycards. Get them and open the doors on both sides of the room for the Cyclones.

Hint: Air Force One: Air Base: Better start:Instead of going through the lasers and trying to get to the ladder, go around the lasers until you reach a location with enemies that shoot at you. There will be a elevator here. Take the elevator up, then turn right and go up the stairs until you reach a shuttle. This will start you outside the double doors, before the stairs.

For an even easier way to get into Air Force One, use the following steps. Enter the elevator near the safe contains the evidence. You will go down all the way, but if you immediately close the doors at the bottom, you will go to the floor above -- which will take you directly to the entrance to Air Force One. However, if you have anyone following you, they may keep pushing the elevator button. If they push it once, you should push it once, either as you are going down or when you are at the bottom. Or, just try to kill all the guards following you.

Hint: Air Force One: Air Base: Quick completion:Once you have gone into the first elevator (that moves diagonally), go down the corridor. There should be a computer with words scrolling down it. If you blow this up, the lasers in the big square hall should malfunction and flash on and off, allowing you pass through. Kill the guards first, as they will shoot at you and push you into the flashing lasers.

Hint: Area 51: Escape: Easy invincibility:When the conversation about who will be left behind to open the hanger doors begins, immediately go to one of the consoles that open one of the hanger doors. Doing this will prevent Joanna from volunteering for the job. Keep pressing B until the console message says "Outer hanger door open". Quickly run to the other console and press B again. The level will then be completed -- you will not need to get on the hoverbike and escape, and a lot of time will be saved. The key to doing this in time is to quickly initiate the conversation with Jonathan and Elvis.

Hint: Area 51 Escape: Twin Falcon 2s:Go back in the operating room. Next to the fumigated surgeons are the guns. Make it quick though, or you will end up like them.

Hint: Area 51 Escape: Double Falcon 2 scoped:For this to work, you will have to give a little bit of your health. After the intermission sequence featuring the scientist turning on the gas, they die. However, what it did not show was that one of the scientist dropped two Falcon 2 scoped pistols. To get to them, you must go through the doors, get the guns, then get out.

Hint: Area 51 Escape: Remote mines:If you manage to put Elvis in the hiding place in less than 36 seconds, you will see an ammo box with the three mines.

Hint: Area 51 Infiltration: Rocket Launcher:Behind a fence near the tunnel to the place you place your comms rider will be a Rocket Launcher. Throw a grenade to blow up the mines near it. You can also use the small crawlspace.

Hint: Area 51: Rescue: Double silenced Falcon 2s:In the Area 51: Rescue level, go up the first ramp and turn right. Go to the stack of crates in the corner. Behind it, instead of where a crate should be, will be a blue object. Shoot it and get the Falcon 2.

Leave the crate, then shoot the three guards, One will come at you (in front of you), one will come around the corner, and the other one will be at the same place as the first. Next, get out of the hallway and turn right in between the stack of large creates. Go to the end then turn right. You will see an area where a crate is out of the stack. There is a drum barrel in that spot. Shoot it and duck inside to get your other Falcon. Watch out for other guards.

Hint: Area 51: Rescue: Wall:There is another way to get through the wall in the Area 51: Rescue mission without using the bomb crate. Throw your Dragon onto the ground with the proximity self-destruct on. Back away and use you pistol to blow up the gun, causing the way to break open. There will be another, more powerful, gun once you get inside.

Hint: Area 51: Rescue: Phoenix:Go up the first elevator and turn right. Go to the locked door and wait awhile. A man will open it. Follow him to the elevator. Go up the elevator and keep going through the doors until you get to a large, brown room. Look around to find a bench with the phoenix.

Hint: Area 51: Rescue: Save time:Instead of going through the trouble of taking the crate to the X, get a Dragon, throw it near the X, and shoot it. You will not be injured if you are far away, and it saves time. Do not shoot the crate at the beginning, or you will fail the mission.

Hint: Area: 51: Rescue: Destroying the hole:There are three ways to blow up the hole in Area 51. One way is bringing up the crate -- it is a lot of trouble and if someone shoots it while you are holding it, you will get hurt. Another way is to throw your Dragon by the crack and shooting it. The best way is to get the Phoenix. Go up the first elevator and turn to the right. Follow the lab technician to the elevator and kill him when he ducks. Go through the elevator and the three doors. Once you get to the large room, pick up the Phoenix on the edge.

Others have talked about how to make the hole without using the crate, but it is false -- that you cannot complete your mission objective if you blow up the crate. You can use the crate to take out the three men around the corner where you begin -- plus you will get to see "Objective Incomplete" in green when you do blow up the hole.

Hint: Attack Ship: Covert Assault: Slayer:Use the Fly-by-Wire rocket to obtain this. When you get up in the elevator with Elvis coming up as well, keep going straight so you can find it and crank it up.

Hint: Carrington Institute: Defense: Have Jonathan as backup:Some players may have noticed that doing some things in some parts of Perfect Dark affect what happens in later levels. This fact will help you get some help from Jonathan in the Carrington Institute mission. To get some help from Jonathan in that mission, begin by going back to the Area 51: Escape level. At the very end of the level, Jonathan will run to open the hangar doors. Before he reaches the metal ramp, run and stand on the ramp before he gets to it. If this is done correctly, Joanna will tell Jonathan to escape with the alien. After you have opened the doors via the control panels, you will have to escape Area 51 from a second exit. If you can complete the stage this way, Jonathan will repay you by standing by Dr. Carrington's office in the Special Agent difficulty setting and shoot enemies, as you use the laser to open the safe.

Hint: Carrington Institute Defense: Destroy sensitive information quicker:If you get the Devastator (save all hostages on top floor), you can just blow up the information.

Hint: Carrington Villa: Devastator Grenade launcher:Destroy all the crates in the beginning on the level. Then, when you get to the Villa, take out the Sniper on the wall above you. Next, move on to the helipad. There are three crates, one has a shield. Pick it up, then shoot each crate. The grenade launcher will appear from the one that explodes. Note: You only will have six rounds for the weapon.

Hint: Carrington Villa: Falcon 2:Disarm a guard and he will usually pull out a Falcon 2. Shoot the guards in the leg after they have been disarmed, and they will either surrender or will run off, leaving a small blood trail behind. Knock the guards out and they will still move on the floor when you punch them. When they have been shot, then they will just lay still.

Hint: Carrington Villa: Extra ammunition:In the tunnel caves that you have to move through after saving the negotiator, there are stacked gray boxes. Blow them up to get ammo boxes for the CMP150.

Hint: Carrington Villa: Explore level:Once the agent with the keycard has opened the door to the room that Carrington is in, the mission is over. However, if you want to see what is inside, play the level in a cooperative multi-player match. Have the agent with the keycard open the door, but block its path so that it does not open all of the way. The door opens toward you -- slowly back up with the door only enough to keep it open for the other agent to get in. Only one agent at a time may explore.

Hint: Carrington Villa Hostage One: Devastator:At the helipad (with a sniper guarding it), you should find some more cargo. Shoot the left one for the Devastator.

Hint: Carrington Villa Hostage One: Double CMP150s:If you eliminate the sniper guarding the helipad in under 38 seconds, he will drop twin CMP150s. This is almost impossible to achieve under the "Perfect Agent" difficulty setting.

Hint: Carrington Villa Hostage One: Sniper Rifle:Look in the bathroom when playing under the "Perfect Agent" difficulty setting, where a shield would be under the "Agent" difficulty setting. You should find a sniper rifle at that location.

Hint: Chicago Stealth: Bombspy:Go to where the dumpster and the explosive barrels are located. Move the dumpster next to the barrels. Blow it up and get the Bombspy.

You can use the Bombspy to create an alternate diversion other than reprogramming the taxi. Fly it over to the end of the level where the guards are located. When they are all around it, detonate the bombspy and you will complete the objective. Note: This will not work out perfectly every time.

The Bombspy in Chicago is essential to reaching your target time on Perfect level. Once you get used to using it, you will prefer not to reprogram the taxi. The game does not allow you to complete the final objective until all of the guards around the freight elevator are dead. If you miss one (or two) with your Bombspy, find him, kill him, and you will be in the clear. The important thing to destroy is the control box in front of the freight elevator. When a guard touches that, you will fail the mission.

Enter the room with the oil drums and the dumpster. Knock out the two CIA agents if you must, but you have to push the dumpster as close as possible to the drums. Shoot the cans until they explode to get a briefcase with the Bombspy. There are more hints...

You have to open the steps leading up to the entrance on Special Agent. If you go down an alley in the area where the steps are located, there is a skip. Place your Remote Mine on it, then blow it up. There is a Bombspy inside.

Hint: Chicago Stealth: Another Falcon 2:Enter the Pond Punk Club, which is the room next to the limo. When you enter, be careful of the man that is down the ramp -- pick him off quietly to prevent alarming the other guards in the room below. Now, stand outside the door and equip your Falcon 2 scope. Open the door and fire your guns to alarm the guards in the locked room. When the door opens, you will notice that you are in a strip club. Run to your left to the bar and get your Falcon 2.

Hint: Chicago: Strip club:Go by the limo and you will see a pair of doors. Go through them and down the ramps. Disarm the guard and he will open up the locked doors leading to a room with a pole on a table and a bar.

Hint: Chicago Stealth: Always access Pond Punk:Enable any or all the cheat codes. Get to the area where you destroy the box to get the Bombspy. Destroy the box with any explosive and walk over the white suitcase that appears. Then, open the door by the limousine to go down the ramp to get into the Pond Punk. Kill the guards by any method. Use the Farsight to see through the locked door that lets you enter the Pond Punk. Fire a shot besides the man standing inside. He will open the door to try and kill you -- kill him. Then, go to your left and enter the restroom. Walk to the last stall all the way at the end of the restroom. Equip the Bombspy. Fly it into that stall, then press Start to unequip the Bombspy. Walk all the way back and leave the Pond Punk by yourself. Once the doors close you will see that you cannot get back inside by pressing B. Press Start again, equip the Bombspy, and fly it to the door. Press B to open it. Then, fly the Bombspy back to where it was and unequip it. You can now walk yourself back inside the Pond Punk.

Hint: Complex: Hidden area:There is a slightly hidden area in the multi-player level "Complex" that is very easy to reach. Just look for a small area in the wall that has metal grates on three sides. You can climb up one of the sides. Then, run on the roof over to an item in the opposite corner (Item #5).

Hint: Complex: Ramp trick:Think of the main room in Complex that has two big ramps and a sniper window looking in. If you ever feel cornered, just run under a ramp, as though you were trying to climb up the ramp from the back. It looks like you are going to have to duck down to fit, but at the last second you will magically pop up on top of the ramp, which will disorient your opponent enough to let you turn around and run off up the ramp.

Hint: Counter-Op levels:Have one human player take control of Joanna and another human player take control of a guard. Have the player as the guard kill the other guards for Joanna to easily pass the level The other guards will not shoot back - they will just run away if they are not killed.

Hint: Crash Site Confrontation: Proximity Mine:Go to Elvis before completing any objectives. He will hand over a mine to you.

Hint: Crash Site Confrontation: DY357-LX:This is difficult to do. If you can disarm Trent before he shoots you, shoots the president, or runs away, you will use his own custom built DY357-LX.

Hint: Crash Site Confrontation: Trent's Golden Magnum:Play the level under the Agent difficulty setting. Note: In the Air Force One level, make the jet bike go into the hole it goes to be dropped off at the next level, which should speed you up. Start the level and find the jetbike quickly. Get on the jetbike and go to where you sound the distress beacon, killing the two guards on the way. Take their Avengers and sound the distress beacon. Then, take a path to where you snipe the Presidential Clone. When you get there, there will be many guards in your way. Snipe the clone and get of your bike. After that, find a big path that should lead you to where Trent and the President are located. Blow up the sentries and quickly disarm Trent before he shoots the President. The gun you took is Trent's Golden Magnum. It will help you kill the many guards that will be on your trail. Then, take the path out of the cavern to Elvis' ship, killing guards on the way if they shoot at you.

Hint: dataDyne missions: Target practice:While in any of the dataDyne missions, either from the roof or from a broken window (windows can be shot out), aim for the passing vehicles and blow them up.

Hint: dataDyne missions: Force guards to surrender:Find a guard then take any and all ammunition, guns, or any other weapon you can find around you and him, so that he cannot roll around and pick them up. Become unarmed and enter disarm mode. Press Z to take his gun. He will stand there with his hands in the air and say similar to , "I don't like this anymore", or "I give up, don't hurt me". Note: You cannot take them as hostages. Basically what this does is makes them worthless. Even if other guards are around, they will not fight anymore.

Hint: dataDyne missions: Flying guards:Enable the "Invisibility" cheat and sneak up behind a guard sitting at a desk. Plant a Remote Mine on the base of his chair. Walk away from the guard and detonate the mine. The guard will be launched many feet into the air, and possibly through the roof.

Hint: dataDyne: Defection: Defeat CassandraTo defeat Cassandra and the woman in the red, knock both of then out by switching your unarmed attack from punch to disarm. Then, exit the level. This can be done under any difficulty setting.

Hint: dataDyne Defection: Laptop Gun:Begin the level under the "Perfect Agent" difficulty setting. When the person that logs in the computer with the files comes out, let him "escape" for awhile. He will eventually lead you to a room with the gun. Its secondary function will be useful at the first floor.

Hint: dataDyne: Defection: Secret entrance to Cassandra's office:Start the level and go to where the cheese is located. Go down there and shoot a rocket (or grenade) at the opposite wall from the ladder. A hole will appear, leading to Cassandra's office.

Hint: dataDyne: Defection: Shoot flying ships:When in the hallway of the office area, walk up to one of the windows. Shatter the window and you will see flying ships outside at a distance. Take out any gun, and aim carefully. If you manage to hit a ship, you can take it down with a single shot and make it explode in mid-air.

Hint: dataDyne Extraction: DY357:The best way to get this hidden gun is with cloaking. Take out the first five troops (do not worry about the ones at the stairs) with head shots. Do not miss, or they will know that you are there. If you pull it off, the fifth one behind the couch will have the magnum.

Hint: dataDyne Extraction: Dragon:You will need Cassandra's keycard to get this gun. Get in her office and pick up the grenade. Throw it (or any other explosives, if you have any) in one of the right corners in the room. One of the walls there will have a hole in it. Look inside to find the gun. The wall that will blow up is the one with a man carved in it.

Hint: dataDyne: Infiltration: Exploding cars:When you are on top of the building, first kill the guards that are on the lower level of the roof. Once that is done, lean over the edge and shoot at the cars. One or two bullets will make the car explode. Note: Enable the "Unlimited ammo" or other of gun cheats to avoid wasting ammunition.

Hint: dataDyne Investigation: Twin CMP150s:The best way to get your hands on these is to use a cloaking device, since you need to be stealthy. Shoot the first guard without being seen. Let the yellow robot take you in and shoot the glass to drop down. Blast the next two guards, and do not give them a chance to notice you. If you do it all undetected, a computer down there will open the white weapon compartment.

Hint: dataDyne Investigation: Proximity mines:Do a quick lap around the lab with the isotope, to pick up some mines. Unless you have cheats enabled, be prepared to take damage.

In the area with the radioactive isotope, send the Camspy around the back of the circular hallway to see an ammo box. If you go in as Joanna around the hallway quickly, your screen will only be blurry. You will get one proximity mine, which you can use outside the door of the room that you have to download the password to get to Dr. Carrol.

Hint: dataDyne Investigation: Shield Tech item:On the second level of the solo missions, there is a secret item called a "Shield Tech Item". To get it, go to the room with the troopers (before the hall with the sentry turrets). Look around the room. There will be a smaller restricted door. Go inside and continue until you reach the end. You will se a wall like the one Dr. Caroll was in. Walk through it when it opens, and the item will be on the table. The shield will help you get past the turrets in that hallway if you have low life.

Hint: Deep Sea Nullify Threat: Proximity mines:One of the cloaked guards behind the first four doors will drop the mines if you can kill him before Elvis does. However, under the "Perfect Agent" setting, you will get them no matter who hits him.

Hint: Deep Sea Nullify: X-ray intermission:Get to the point in co-op mode where you see Dr. Carrol. Have player one stay behind while aiming the Far Sight. The player one screen will be in X-ray aiming mode. Have player two go into the room and while the intermission scene is playing. The cut scene will then be in X-ray mode.

Hint: G5 Building: Reconnaissance: Crossbow:Inside of G5 building, use the punch to defeat the cloaked guards to get a crossbow. You can get some arrows back if you return to the place that you kill the guard.

Hint: G5 Building Reconnaissance: N-Bombs:You can get this under the "Special Agent" and "Perfect Agent" difficulty settings only. If you placed your mine on the highest blocked up door on the last level, then head up there very quickly and get the bombs right next to the exit.

Hint: Maian SOS: Easier mission:When you wake up, walk toward the door about two steps to make the first scientist pull a gun, then steal it. Play through the rest of the mission until you pass the next three doors. Make sure you have some Psychosis ammunition. Turn right, kill the two guards with Dragons and the guard with 1000% life. Two DY-LXs will appear to take you out. Under the Agent difficulty setting his accuracy is about 30-45% -- take your time to shoot him in his chest. This does not phase him as much as a limb or head shot. Under the Special Agent difficulty setting be more aware because he has 1200% life and 50-60% accuracy -- dodge and shoot. Under the Perfect Agent difficulty setting, he has 1500% life and 90-100% accuracy -- sneak, peek and shoot.

For an easy path through Maian SOS, instead of killing the man with the two DY357-LXs, shoot him in the chest with the Psychosis gun so he will not limp, He will run, with you killing anyone who gets close enough to him before they have a chance to shoot you.

Hint: Mr. Blonde's Revenge: Extra CMP150 ammunition:On the first floor where all the guards have CMP150S, find a guard that has two CMP150S and shoot her in the hand. She will drop her gun from that hand. Collect the gun she dropped and wait. Once she recovers and gets ready to shoot again, she will have two CMP150s again. Repeat this to get more ammunition for that weapon.

Hint: Mr. Blonde's Revenge: Difficulty access:Finish the game (preferably on the Agent difficulty setting) to unlock the extra mission, Mr. Blonde's Revenge. Finish it on the Agent, Special Agent, and Perfect Agent difficulty setting. It is not as difficult as other missions. Normally to play the next difficulty setting on a level, you would have to play through the game's missions in order. However, if Mr. Blonde's Revenge is completed on all difficulty settings, you can access the next difficulty setting of a mission without having to play through the rest of the game. Strategy for this level follows. Keep in mind that you start off with a Mauler, a Bomb Spy, a Skedar Bomb (for Special and Perfect Agent) and a Cloaking Device with 30 seconds. When escorting Cassandra, make sure to always be near her and pointing your gun at her so that she cooperates faster. This is especially important on the Perfect Agent difficulty setting.

Agent: Start by strafe running to the left until you reach the corner. Turn on the cloak and quickly access the elevator on your left if you are facing the edge. Next to that elevator in the corner is a shield. Take it while waiting for the elevator and turn off the cloak while you are in there. Wait until you hear or see it come down. Turn the cloak back on and board. Once inside, take off the cloak and equip the Mauler. Do not get off at the first stop. Once you make the first stop, close the elevator to go one floor up. Kill the guard in front of you and run into Cassandra's office before the other guards come for you. Select unarmed and use disarm. Cassandra will try to shoot you with a Falcon 2, but she is a terrible shot; just strafe out of the way and disarm her. Mr. Blonde will threaten her; point your gun at her so that she cooperates. She will keep talking and running for the helipad. Keep your gun pointed at her and run from the guards on the way to the stairs. Once all the way up the stairs, there will be two dataDyne male guards with DY357 Magnums and N-Bombs on the catwalk upstairs. Keep relatively close to both of them, but not too close. Take them out with the Falcon 2 before they get a chance to throw their N-Bomb. Keep going upward to the helipad and make sure you are near Cassandra and you will board the Skedar ship and finish the mission.

Special Agent: You have an extra objective, which is to take out the elevator to the labs. Turn on the Cloak and quickly strafe run left through the door, right to the corner, and straight through the fake wall to the elevator. Pause and equip the Skedar Bomb and press Z in the elevator to place it. Quickly run upstairs and take the same elevator as before and do the same thing except there will not be a shield. Do the same thing as under the Agent difficulty from here onward. The only difference is that it is easier for Cassandra to be immobilized by the guards with N-Bombs -- keep them from throwing those.

Perfect Agent: You have a time limit on this difficulty setting, displayed at the middle-bottom of the screen. Do the same thing as the Special Agent difficulty setting until you reach the stairs. The usual one is locked -- take the other one. If you completed objective one and got to the correct elevator fast enough, it should be open. The best thing to do would be to do just that. Equip the Mauler and shoot the side window to the left if you are facing the entrance four times. If you were fast enough as to take off the stealth at the correct time, you should have about 14 or 15 seconds remaining. When the elevator comes to a stop, wait about four seconds and turn on the stealth. Wait until the elevator on the side stops. Quickly kill the guard over there and objective two will be complete. Get off of the elevator on the first stop and you will hear gunshots. Ignore them and stay away from the elevators' side so that you do not get shot. Go to the door on the left past the two elevators that lead to stairs. If you used the cloak correctly, you should have about seven seconds remaining. Go through the door and turn on the stealth. Ignore the dataDyne guard here and go up one floor to the next door. Go through the door and ignore the bodyguards here as well. They should run past you and into the stairwell. With your last second(s) of cloak, shut the door on them once they are all inside. Run straight and hide behind a wall. Use the Bombspy to activate the elevator. You can now do one of two things. You can open up the stairwell with the Bomb Spy and make it explode when there are two or more guards there, or wait for the elevator to come and kill the bodyguards and guards in there. Usually there will be dual Falcon 2s in there from the security chief. If they are in there, make sure to equip them. Make sure to be wary of the dataDyne guards as they will often throw N-Bombs at you. Finish objective one as usual, except by being more cautious and elusive. When you make it to the room just before going outside with the two guards, do not be as cautious and just shoot.

Hint: Pelagic LL Exploration: Double Falcon 2s:One of the guards in the gangplank-like area will give up his double silenced Falcon 2s if you are unusually stealthy. You will get them if you can stop him before he or any of his shipmates set off the alarm.

Hint: Pelagic LL Exploration: Kill Elvis without failing:When you have completed all objectives besides number 3 (to find Elvis), go near the room where Elvis is located. Stand so that you do not pass through the doorway. Take out the CMP150 on secondary fire and target Elvis. Go through the doorway, wait about 4 or 5 seconds, then fire. If you done correctly, you will complete objective 3 and Elvis will be dead. When you throw the box to Elvis in the intermission scene, he will not be there.

Hint: Skedar Ruins: Battle Shrine: Quickly Defeat the Skedar Army:In the last stage of the standard missions in Perfect Dark are a series of quick and fierce Skedar equipped with mauler pistols. There is a way to quickly and easily defeat them before they can become a deadly challenge. To do this trick, save two Devastator rounds until that point. Also, be sure to pick up the two Slayer Rockets that two Skedar guards tried to kill you with earlier. Combined, this is four rounds of explosive weaponry. When you first arrive in the Skedar suspended animation room, set the Devastator on "grenade launch" and blast two pairs of the Skedar suspended animation tanks. Next, use the two Slayer rounds to eliminate another pair of Skedar suspended animation tanks. The resulting explosions should have killed all of the Skedar before they can react to your presence. If not, just open the suspended animation tanks and shoot them -- before the aliens awaken. Note: This will help you along in earning the "All weapons" cheat on the "Perfect Agent" difficulty setting on that level.

Go all the way through the room where the army attacks you, open the door, and go through it to enter the small room. Close the door, stand away from it, and wait for about a minute. The Skedar do not seem to understand the concept of opening doors, so they will not enter that little room. After waiting for about a minute or more, pull out your Devastator and fire a grenade at the door on wall hugger mode. The grenade will drop, explode, and destroy the army without you ever seeing it. It is much easier than taking the army on, and it saves a lot of health for the Boss.

Note: You must have the twin Phoenixes to do this trick. Just before you go into the room with the Skedar Army, step into the doorway just enough that you can see the end row of tanks, but so you do not force them out. Shoot an explosive shell at each one of the visible tanks until you hear a roar. Then, bring up your Callisto NTG on High impact Shells mode and walk up to the tanks one by one. Shoot the Skedar through the green doors. For some reason while they are in their tanks one head shot will kill them. If they open, they are at full health. When that is finished, pull out your double Phoenixes on explosive shells and walk into the Boss room. Watch the Boss closely. If he lifts his staff above his head, watch the corners near him -- either a big or a small Skedar will appear and come after you. If the boss disappears, move around without stopping. If you stop, the Boss will uncloak next to you and hit you with his staff. Also watch for him to go to the left or right on his platform and hold still. Quickly shoot him with the Phoenix with an explosive round because he is trying to shoot a Slayer rocket at you. It will explode if you shoot the Phoenix at him just as he launches it. It will deplete his shield and he will go to sit on his throne beneath the shrine. He will recharge his shield, but this takes the shield off the shrine itself. Shoot the bottom row of spikes on the shrine and one will break. Then, the Boss will get up and run around again. The next time he sits down again, shoot the spike across from the first one you destroyed. Then, the next times he sits down, destroy the next row of spikes and finally the main spike that points straight up. It will fly up into the air and run itself into the Skedar leader's head.

Hint: Skedar Ruins: Battle Shrine: Double Phoenixes:After you complete objective one there should be two "fake" pillars remaining. Use a wall hugger from your devastator and blow them up. At the place where drop into ravine or canyon you should pick up a single phoenix, but it will instead be a double phoenix. Save it to use inside the shrine.

Hint: Skedar Ruins: Battle Shrine: Jump across chasm:The first chasm that you reach can be jumped across. Run over the left corner of the ladder on your side.

Hint: Skedar Ruins: R-Tracker:Kill the first few guards when you enter where the invisible bridge was located. Watch out for the Skedars with Slayers. When you get to the Boss, do not go in. Instead, stay there and he will not do anything.

Hint: Temple: Slayer Rocket:The temple level in multi-player mode is the only level where you can fire a Slayer Rocket anywhere. In the main room, there are holes in the tops of the walls and a hole in the floor that can be used to get around any door that may be closed. If you set the weapons to include the Laptop Gun you can become invincible by using the Sentry and waiting on the respawn point of the Slayer. Note: The Slayer is impressive and can shoot down other rockets, patriot missile-style However, it can also be shot down itself by automatic weapon fire.
