Space Attack

Space Attack is a game released for the Atari 2600. It is an adaptation of the Intellivision game Space Battle.

Gameplay
Six alien fleets of different sizes are attacking your mothership, and it's up to you to defend it using your three squadrons. Alien ships will dodge your attacks and will attack you with photon blasts.

There are two game modes; Radar Mode, which is more strategy, and Battle Mode, which is all out action. In Radar Mode, select which of the three squadrons you have on hand to go after the selected alien fleet. In Battle Mode, use your target tracker to aim at the alien ships.
