Space Battle is a one-player game that pits you against the computer. Five 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 requires more strategy, and Battle Mode, which is all-out action.
Gameplay involves controlling your three squadrons as they battle against the alien fleets. You must use your radar to track the movement of enemy ships and target them for destruction. The computer-controlled aliens will not go down without a fight, using their photon blasts to attack you. With multiple game modes to choose from, you can switch between strategy and action depending on your mood.
