This video game is an Atari 2600 port of Spacewar!, the famous 1962 computer game by Steve Russell. The cartridge comes programmed with 17 game variations. Variations 1 to 13 are duels between two ships and 14 to 17 are for one player. In some of the variations the ships fight near a planet which has gravitational attraction. This concept was used in the Star Control series of games.
