Cheese

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

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) and you will see weapons from GoldenEye 007 (Klob, KF7 Solviet, RCP-90, AR 33 Assault Rifle, etc.).

X-Ray mode ending

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

Night vision ending

Turn your night vision goggles on just before the end of a level.

Invisible during ending

Collect the Cloaking Device in the game, then activate it just before the end of a level. Your character will be invisible during the ending sequence. -From: burke.com

More simulants

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

Daniel Carrington comments

Go to the firing range in the Carrington Institute 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: Hostage One level in solo mode, shoot out all the bottles at the end of the level. Once they are all destroyed, you will hear Daniel Carrington say, "Act your age, Joanna."

Get locked in closet

Select co-operative mode, then go to the Air Force One: Anti-Terrorism 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 (the 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 closets you will not have that key card and will be locked in.

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.

1000% handicap advantages

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

Raise 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 will 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).

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 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 in the three or four player challenges. -From: cooldude-zone.net and BMS1986.com

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 press Start 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.

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.

Shoot at other people at firing range

Go to the firing range in the Carrington Institute. After entering the firing range, 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.

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 and use the throwing knifes on him.

Target practice in Datadyne levels

While in any of the Datadyne levels, either from the roof or from a broken window (windows can be shot out), shoot the passing vehicles to blow them up.

Detonate Remote mines easy

Press A + B to detonate a remote mine without changing the remote mines function.

Slayer controls

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

Slower slayer fly-by-wire rocket

When you have the slayer, change it to the secondary mode. When you fire the rocket hold R to make it go slower for easier turns and maneuvering. Release the button to send it speeding towards your opponent/enemy.

Easy kills with the slayer

When you have your opponent in your sights and you cannot turn the fly-by-wire rocket around in time, press Z again to self-destruct it.

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 as in GoldenEye 007, but it is better than the regular method. Note: This does not work with the shotgun or crossbow, and is not recommended with the laptop gun.

Quick shot with secondary 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.

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.

Fast running

Turn left or right until your cursor is approximately 30 degrees to the left or right of where you want to run to. Then, hold Analog-stick Forward (Up) + 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.

Circle attacks

This is a simple move, but priceless to master. Hold Analog-stick Left + 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 Right and 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.

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.

To earn all medals much quicker, 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 will get all four medals every time if you only use one bullet to kill the second character.

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, C-Up, and C-Down, then take it out with one shot.

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 and 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.

Team motivation
During a game in multi-player mode, hold A to display the quick menu. Press Z(2) and you can control who attacks, and who stays with you. There are a few selections to choose from, which do the following:
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.

Note: You must have a 2.2 or higher version of the Game Shark to use these codes.

Note 1: You must have a 3.2 or higher version of the Game Shark to use this code. If you cannot use this code, then you must turn the Code Generator on every time you use the Game Shark with this game. However, if you can use this code, then you never have to use the Code Generator.

Note 2: Use the Expansion Pak and start a new file. Play one round in the combat simulator, then save the game. Remove the Game Shark, then start the game again. Play a solo mission, go to cheats, and they should all be unlocked. -From: Sharkfan87.com
