Wolfenstein: Enemy Territory is a free and open source multiplayer first-person shooter video game set during World War II. It was originally planned to be released as a commercial expansion pack to Return to Castle Wolfenstein and later as a standalone game. However, due to problems with the single-player aspect, the multiplayer portion was released on 29 May 2003 as a freeware standalone game. In January 2004, the source code for the game logic (not the game engine) was released to the benefit of its modding community.

The game uses a modified Return to Castle Wolfenstein engine, itself being a heavily modified id Tech 3 engine, which has been open source since 2005. As of the first day of the 2010 QuakeCon, 12 August the entire source code was released under the GNU General Public License v3. Multiple source ports have been started. While the work by the OpenWolf and ET:Xreal teams concentrate on innovating the renderer, the most active community project, ET: Legacy, focuses on fixing issues by backporting improvements from ioquake3 while staying binary compatible with the original game client, server and its mods.

Wolfenstein: Enemy Territory is an online multiplayer game, wherein the players interact with each other over a network, in two teams (Allies and Axis) 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. In public games, PunkBuster used to protect the game, however its developer, EvenBalance, discontinued support for the game in October 2011.
