Enemy Territory: Quake Wars (ET:QW) is a first-person shooter video game, and is the follow-up to Wolfenstein: Enemy Territory. However, it is set in the same science fiction universe as Quake II and Quake 4, with a minimal back-story serving as a prequel to Quake II. It is the second multiplayer-focused game in the Quake series (after Quake III Arena). Quake Wars features similar gameplay to Wolfenstein: Enemy Territory, but with the addition of controllable vehicles and aircraft as well as multiple AI deployables, asymmetric teams, much larger maps and the option of computer-controlled bots. Unlike the previous Enemy Territory game, Quake Wars is a commercial release rather than a free download.
Enemy Territory: Quake Wars was developed by Splash Damage for Windows using a modified version of id Software's Doom 3 engine with MegaTexture rendering technology.
It was announced on February 13, 2007 that Enemy Territory: Quake Wars will also be released for the Xbox 360 and Playstation 3 in summer 2008. On May 21, 2007, it was announced that Aspyr Media would be releasing the title for Mac OS X. On March 18, 2008, the Mac OS X version started shipping.
