DOOM 3

Doom 3 is a 2004 first-person shooter survival horror game developed by id Software and published by Activision. It was originally released for Windows on August 3, 2004, before being adapted for Linux later that year, and ported by Aspyr Media for Mac OS X in 2005. Vicarious Visions ported the game to the Xbox, releasing it worldwide on April 4, 2005. Doom 3 is set on Mars in 2145, where a military-industrial conglomerate has set up a scientific research facility into fields such as teleportation, biological research, and advanced weapons design. The teleportation experiments open a gateway to Hell conducted by Doctor Betruger, resulting in a catastrophic invasion of the Mars base by demons. The player controls a space marine who fights through the base to stop the demons attacking Mars and reaching Earth. Doom 3 is the first game that utilizes the id Tech 4 game engine. The engine has since been licensed out to other developers, and later released under the GNU General Public License v3.0 or later in November 2011. Doom 3 was a critical and commercial success; with more than 3.5 million copies of the game sold, it was the most successful game by developer id Software up to that date. Critics praised the game's graphics, presentation, and atmosphere, although reviewers were divided by how close the gameplay was to that of the original Doom, focusing primarily on simply fighting through large numbers of enemies. The game was followed by Resurrection of Evil, an expansion pack developed by Nerve Software, in April 2005. A series of novelizations of Doom 3, written by Matthew J. Costello, debuted in February 2008. An expanded and remastered edition, Doom 3: BFG Edition, was released in the fourth quarter of 2012. It has been ported to various platforms, including some which enable portable and virtual reality gameplay.
