Starmaster 1982 By: Activision

Storyline:

"You must protect your starbases by destroying all invading enemy starfighters before they destroy you or your starbases. You must accomplish your mission quickly, using the least amount of energy, sustaining the least damage. Succeed, and you will be rewarded. Fail, and you will be destroyed. The destiny of the galaxy is in your hands."
