Doom 3 Cheats
How to use these cheats
Button names refer to the Xbox controller — A, B, X, Y, the LB/RB bumpers, LT/RT triggers and the D-pad. Unless told otherwise, enter codes from the pause or options menu, or while playing. Some cheats disable achievements for that save — keep a separate save before you start.

Hold the Left Trigger and tap these button combos during gameplay. A sound confirms each entry. God Mode cannot be enabled until after the first elevator ride, and it switches off every time a new area loads so you must re-enter it. The Limited and Collector's Editions of Doom 3 also bundle Ultimate Doom and Doom II; their codes are tagged classic and are toggled off by entering them again.
