Enemy Territory: Quake Wars pits the armies of Earth against the invading alien Strogg in the ultimate online strategic shooter. Featuring strategic team play, persistent character promotions, day and nighttime combat missions, and the universe's most powerful weapons and vehicles, Enemy Territory: Quake Wars transports players to the front lines of an epic new war for Earth.

As the invasion begins, players choose to battle as one of five unique classes in either the EDF (Earth Defense Force - humans) or the barbaric alien Strogg armies, each augmented with specialist weapons and combat hardware. Troops utilize over 40 conventional and futuristic vehicles, deployable structures, and defense systems like quad-bikes, tanks, and alien walkers for epic ground assaults; or helicopters and anti-gravity ships to lend firepower from the air. Throughout each battle, teams establish bases, deploy defense structures, artillery, radar, and advanced forward-command systems into enemy territory while constructing and demolishing obstacles to speed progress and gain a tactical advantage over the enemy.
