Space War (Atari)

Space War is a game released for the Atari 2600. It is based on the arcade game Space Wars.

Gameplay
It is basically a space version of Combat with the gameplay of Asteroids. You and your opponent control a spaceship in which your goal is to score more hit points on your opponent's ship without letting him do the same to yours within a time limit. Options for this game include wraparound and enclosed playfields, plus gravitational effects from the Sun in the middle of the screen (black hole, negative gravity, and no gravity). In some variations, you and your opponent do not engage in combat but must collect as many of your own colored space capsules as possible within a time limit.
