Doom 3 Cheats
To enable the cheats in Doom 3, press the Tilde (~), Control and Option keys simultaneously to bring up the console and type in the code you want to activate. Some codes, such as god mode, may need to be reactivated each time you enter a new level, start a new game, or load a saved one. The up arrow on your keyboard enables you to cycle through codes previously entered during the current gaming session, which saves plenty of typing time. Press the Tilde key to close the console.
When you jump ahead to another level in the game with one of the map codes, you start with the weapons you would have had if you accessed it through normal gameplay, along with a small amount of ammo.
