je vous laisse vous débrouiller pour la traduction, et si le premier à les tester peut nous dire si ils marchent... :
How to unlock Nightmare Difficulty:
Finish the entire game to unlock the Nightmare Difficulty Mode on consoles and PC. This a much more difficult version of the game in which your health is always depleting. This works on both Doom 3 & Doom 3: Resurrection of Evil and possibly on Doom 3: The Lost Mission.
How to activate God Mode:
To become invincible, when playing Doom 3 hold the Left Trigger and press the X, Y, B, A buttons (on Xbox) to enter God Mode.
Note: This is untested on Xbox 360 & PS3; on the latter the cheat would be hold the Left Trigger and press the Square, Triangle, O, X buttons (on PlayStation) to turn on invincibility.
How to Skip a Level:
Level Skip can be done on the Objectives Screen in the PDA, hold the left trigger and press the B, A, X, Y buttons (on Xbox 360) or press the O, X, Square, Triangle buttons (on PS3).
