Doom (previously titled Doom 4) is a work-in-progress game anticipated to become the next release from id Software and their third game published by Bethesda after Rage and Doom 3: BFG Edition. Early planning and development began in August 2007, and is currently ongoing. The game will be a reboot of the series, featuring a story detailing the invasion of the UAC Argent facility on Mars by the forces of Hell. The new Doom is being built on a successor to id Software’s id Tech 5 game engine which id Software is calling id Tech 6.
