AssaultCube is an open source 3D shooter that will have you running and gunning in minutes. Experience fast-paced first-person action with the rather impressive Cube engine graphics, especially considering the download size is only 40mb! You can enjoy hours of frantic on-line play and join any number of clans in the expansive AssaultCube community. Though Assault Cube is not the same caliber of FPS as titles like Call of Duty or Medal of Honor, this title is a great play and especially for the price—free. The different game modes as well as the online play make this an expansive game that will provide you with hours and hours of play time.
