    Doom 3 Overview

    Doom 3 is a science fiction first person shooter which was released for PC in 2004. It is a survival horror game which was later ported to the Xbox in 2005 and spawned a movie spinoff starring The Rock.

    Set in 2145 on the planet, Mars, Doom 3 was not a follow on from previous Doom pc games. In the game, a military-industrial organisation inadvertently opens a portal through to Hell, from which all manner of demons invade a research facility and the player takes on the role of a marine charged with the task of finding a way to close the portal and stop the demons invading Earth.

    If you’re new to Doom 3, or stuck on a particular part of the game then a full Doom 3 walkthrough is available on this site. These cheat codes are used to complement the walkthrough, so players can traverse areas of particular difficulty in the game.

    There are many other cheat codes for Doom 3, which give up information found in NPCs’ PDAs and also allow you to skip maps. There are also numerous other cheats for multiplayer action, but for the purposes of this article we are focussing on the most important cheats for single-player games - those which allow you to stay alive and keep stocked up on ammo!
