Although the main focus of AssaultCube is multiplayer online gaming, a single-player mode consists of computer-controlled bots.

AssaultCube utilises efficient bandwidth usage, allowing the game to be run with connection speeds as low as 56kbit/s.

[6] 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.

Another feature of the game is the potential for using the recoil of the weapons (which pushes one backwards) to reach and perform moves that were previously impossible.

The plan was to create an entirely new game incorporating Cube's simplicity and movement style in a more realistic environment.
