Wolfenstein: Enemy Territory is an online multi-player 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.
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. Some objectives may be optional, and some objectives can be carried out by either team. These minor objectives assist the team completing them. Depending on Game Mode the action will continue on another map (Campaign Mode) or the same map (Objective Mode, Stopwatch Mode, Last Man Standing).
