Blue Paintball Darts  -  Here's a funny glitch. In the Interrogation level find the blue spray paint can. When you have done spray all the cameras in the first section and then pull out your dart gun. Shoot the walls and then you will find out you have blue paintball darts. 

Boxed Ethan Hunt/Jump off a boat glitches  -  This code works on both CIA rooftop levels. To use it, go to the level select screen. Select either one of the CIA rooftop levels, but DO NOT go into them. Instead, use the kid mode cheat (C-down, C-up, R, L, Z). Ethan should say: "Hey, that's better!" if you do it right. Go in to the level, then go to the nearest box. Try to climb the box. You will be stuck inside. Use the kid mode cheat again. This time, enter the ICE HIT: Lundkwist Base level. Ethan wont even have time to walk around. He'll fall out of the boat during the introduction. 

Change Camera View  -  In the tunnel, put your gun away and just before you jump on the platform off the truck hit and hold the R button. Now let go of the R button. If done correctly, the view will change so that the camera follows the truck. To fix this view jump on another truck. 

Cheat Codes  -  Need some help? Well, here's some cheat codes to get you weapons and other effects.  Enter these codes at the LEVEL SELECT screen. If you enter these codes correctly, you'll hear Ethan say "Ah, that's better."

Easy Jump  -  On the CIA Escape mission, there is a difficult jump on Rooftop Escape. You have to jump over a laser perimeter fence, which can be difficult. Try a couple of times to see how close you can get to the fence without touching it. Then go to this point and jump. Once Ethan has reached the peak of his jump (you might try this a couple of times) then push forward. He should clear the fence, although you might hit it every now and then. This cheat will most likely help beginners. 

End Game Bonus  -  When you have beaten the game, let the game run through the credits. When the credits have gone by and the Infogrames logo comes up, don't do anything yet. You will appear in the Recover NOC List Mission, in the embassy. Your health will be low, but that doesn't matter.

This isn't a mission, but a reward. Scattered around the embassy in groups of two or three are the production and design team. Talk to them, and they'll tell you what they do. When you finish talking to everyone, Candice and Ethan will come from the security area down to the main floor, near the piano player. When they hug, the party begins! 

Glitch in the Second Subpin  -  Here is a way to give Clutter the mine and AFS without actually getting it. First when you start pull out a gun and walk up the ramp. Pick off the guard that is closest to you. Then walk forward along the edge of the cliff. When the cliff gets bigger walk over the left and stay put. Ignore all the people around you.  It is important that you don't shoot the gun or it might not work. Ethan will say, "I need to find the AFS and the mine for Clutter". Just stay there. Then he'll say, "I still can't receive messages. Sure hope nothing's wrong!" Then he'll say, "I'd better find the AFS and the mine and get back with the guys."

From a distance you will see a guard come running towards the guys when he passes you chase him. Don't let him see you or shoot him, or you will have to start all over again. Follow him down the ramp to where the guard is holding Clutter at gun point. Then shoot the guard and walk toward Clutter. You'll give him the AFS and the mine. Then they will leave. You still need to get the AFS and the mine or you'll lose you mission. 

Piano Player Glitch  -  Go to the embassy. Get at least the mini rocket launcher kill all the guards you see then, go toward the piano player. Punch him and you'll knock him off of his chair. He'll be dead sitting on air! 

Zombie Ethan  -  At the train station when the two guys in black are walking behind Ethan, shoot Ethan until he falls down and then quickly shoot the guy in the front. Ethan will jump up and kick the other guy in the back. He will be invincible to gun fire but dies if some one punches him. 

Zoom Without the Sniper Rifle  -  First you have to select a gun (ex. Dartgun). Then While holding the R button to AIM press The Up and Down C's to Zoom in and out. This may not help you as much as the Sniper Rifle but you'll be able to get more head shots.
