Star Warrior

You are a starfaring knight bound tightly by your code, a mercenary with a cause. You are a Fury, an interplanetary avenger on a mission of justice and danger, called on by the people of the planet Fornax to free them from the rule of an oppressive military governor. You must take on an entire planetary occupation force— alone! Outnumbered by storm troopers of the Stellar Union, you'll always be on the lookout for hover craft, robot tanks, artillery—even the deadly, rapid firing “Mauler". But you’re far from helpless.

Star Warrior is a 1980 science fiction role-playing video game written and published by Automated Simulations (later known as Epyx) for the Apple II, TRS-80, and Atari home computers.
