Genre: First-person, Shooter
AssaultCube, formerly ActionCube, is a free and open source software first-person shooter video game, based on the Cube engine. It takes place in realistic environments, with fast, arcade gameplay. 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. It can run on older computer hardware as well.
