Wolfenstein: Enemy Territory is an online multiplayer game, where the players interact with each other over a network in two teams (axis and allies) to defend or destroy mission objectives. The game is playable over the Internet or a Local Area Network. Like many online games, cheating and exploit communities exist. To counter this, the game has support for PunkBuster, an anti-cheat solution.
There are two sides; Allies and Axis. There are six officially released maps (North Africa Campaign: Gold Rush, Siwa Oasis, and Seawall Battery; Europe Campaign: Rail Gun, Wurzburg Radar, and Fuel Dump), as well as hundreds of custom maps made by the internet community. On each map, the offense needs to complete a certain set of objectives within a limited amount of time. The defense needs to keep the offense from completing objectives until time runs out.
Note: This is V1.0, patches are required.
