Doom 3

On August 3, 2004, id Software released the next advancement in the Doom franchise, Doom 3. Rather than a continuation of the current series storyline, Doom 3 was a retelling of the first game with a few slight changes to both the story and visual display. The game was originally released for Windows and was later ported to Linux. It was also available on the Mac OSX and the Xbox seven months later with the help of Aspyr Media and Vicarious Visions. The Xbox version of the game has less detail but features a two-player online co-operation mode. On April 4, 2005, an expansion, Doom 3: Resurrection of Evil was released and was available for both platforms. The Xbox version of both Doom 3 and its expansion pack are backwards compatible.

The plot of Doom 3 is relatively similar to the original game and features a simple horror and science fiction themed storyline. The player still acts as a nameless marine sent to an extraterrestrial base on a standard mission which is threatened by the unexpected arrival of demons through a teleportation gate. Again the player is forced to fight his way through a variety of demonic creatures in order to escape and eventually arrives in Hell on his way back to Earth. A major difference between the storylines of Doom 3 and the original games is that the setting takes place on the planet Mars rather than its moons. The environment is also shown more accurately as unbreathable while in the original series it was not. Doom 3 also introduces a much more detailed plot including an alien view the story.

Many of the old weapons seen in the previous Doom games return as well as a few new ones. The pistol, shotgun, chain gun, chainsaw, rocket launcher, plasma gun, and BFG 9000 return to the player. A few of the new additions include the flashlight, some hand grenades, and a hand-held assault rifle.
