AssaultCube is a free first person shooter multiplayer game. Produced by Rapid Viper Productions, it is based on the CUBE engine. Anyone who has ever played Quake or Counterstrike will feel right at home here. The game takes place in realistic settings, but the action remains fast and furious. The game has single player and multiplayer modes, but clearly multiplayer is its strong suit. In single player mode you get to play in 26 maps against the computer. There are various difficulty settings to choose from. Playing in single player is a good way to hone your skills and get familiar with the maps.
