AssaultCube, formerly ActionCube, is a free first-person-shooter based on the game Cube. Set in a realistic looking environment, as far as that´s possible with this engine, while gameplay stays fast and arcade. This game is all about team oriented multiplayer fun.
Start up the game, join one of the public servers and team up with some players. Have fun..
