A demo for Enemy Territory: Quake Wars is now available on Xbox Live Marketplace.

Enemy Territory: Quake Wars is a shooter that recently landed on the Xbox 360 and PS3. While id Software supervised the project, the Xbox 360 version was developed by Nerve Software with Underground handling the PS3 version.

Set in 2065, the game sees the armies of Earth’s Global Defense Force facing up against the alien Strogg race in a fight for the planet. Quake fans can choose to battle in the desert, Arctic and tropical environments using either the modern military tactics of the human Global Defense Force or the Strogg’s alien technology.

Players can enjoy mission-based multiplayer warfare both against AI offline and against friends online, with each side featuring distinct classes, vehicles, tactics and weapons. The game features team-based combat with players able to earn experience in order to gain new skills.
