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 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, 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.
