3D objects on it that represented rock formations or occasionally alien plant life. The worlds' backgrounds were digital paintings of alien skies that wrapped around the horizon. The game lacks a save feature. The player has effectively 2 "Continues" - basically, extra lives - and that was it before the game needed to be restarted from the beginning. Experienced players would also soon notice that damage effects to the tank could be overly crippling, reducing the fun of playing or making the game unwinnable on the current life. For example, significant damage to one side of the tank could completely remove the ability to turn in a given direction; damage effects tended to pile up rapidly, since as mobility was reduced, it became harder to avoid further incoming damage or keep enemies away from the tank's wounded side.

He also has a robotic repair droid and an AI computer that contains the personality of his late wife, who was lost in Gir Draxon's first attack on Earth in Stellar 7.

Eventually, they find it as the game nears its conclusion, and the AI destroys the base to prevent Draxon's minions from finding information on the Raven II and using it to defeat the protagonist. After Draxon's is defeated in the final battle, his super-tank overloads,
