Call of Duty 3 Cheats on PlayStation 3

Night Drop mission: Easy completion

When you meet up with the French rebels you will have a choice to go left to the Flak 88s or go through the house to
the right. Go left to the guns. Kill all the Nazis around the gun and in the ditch leading to the next gun. Then, blow up the 88 and move on to the rest of the guns. After you blow up all the guns you will reach the house that you would have had to take if you went right. When you go in the house you must defeat a Nazi that is standing there waiting for you. Kill all the enemies in the house and fall through the burning floor. You will see you allies there waiting for you.

The Island mission: Best gun early

On the second mission, The Island, there will be a man under the second bridge with a FG42 scoped. That gun will get more ammunition every time you kill someone. The gun starts with 96 ammo remaining and you can kill about 150 people with it (not including melee). After completing that mission you will have that gun on the third mission, but you must save the gun through the third mission to get it in the fourth mission and so on.

The Mace mission: Scoped FG42

When you get to the part where you must keep the Nazis from the trenches, do not listen to the men. Go to the right and follow the path. You will find an FG42 scoped leaning on a crate.

Veteran interviews

Successfully complete the game to unlock interviews with veterans Gordon Boulton, Sgt. John D. "Bud" Hawk, and Sgt. Stan Markut.

Move friendlies

To move your friendlies, use ADS and aim at them, then press Fire. Do not worry as you cannot shoot at a friendly. Your friendly should move from his location. This is useful when you are trying to enter an area blocked by a friendly.

Multi-player mode: Avoid being seen

When playing in multi-player mode, you can avoid being seen by going into the tall grass. Keep moving back and forth because the enemy can see you because of the red hash marks.

Saint Lo mission: Capturing the church

In Chapter 1 (Saint Lo), to capture the church you must kill all of the Nazi soldiers (while hiding behind walls). It is best to use the Thompson gun in your arsenal. Once you have killed all of the Nazis in sight, go up to the church and throw two or three smoke bombs in it. After that, throw two grenades in the church while the smoke is still active. Once you have done that, you will be able to go to your destination, capture the church, and be able to move on.
