AssaultCube

AssaultCube was designed to be more realistic and team-oriented than Cube while keeping Cube's distinctive fast-paced gameplay. In comparison to other games, AssaultCube is slower-paced than Quake but faster-paced than Counter-Strike. There are two different teams in AssaultCube, called the "Cubers Liberations Army" (CLA) and the "Rabid Viper Special Forces" (RVSF).

AssaultCube retains a movement bug from Cube that allows players to utilize straferunning to move at a faster speed. This was left intentionally unfixed by the developers because it was considered an enjoyable feature of Cube, similar to bunny hopping in Quake.

AssaultCube started out as ActionCube in July 2004 by a few members of the Cube community. The first official release was in November 2006. The plan was to create an entirely new game incorporating Cube's simplicity and movement style in a more realistic environment.

In May 2007, ActionCube was renamed to AssaultCube due to a request from the developers of Action Quake.

AssaultCube, then under the name ActionCube, was named "Free Game of the Month" by the German video game magazine PC Action in February 2007. AssaultCube was downloaded between 2006 and March 2017 alone over SourceForge 7,456,000 times.

The game was forked into a version with a built-in gaming portal named ActionFPS in 2017. Features include an authentication system and a match client.
