The goal of the game is to take down incoming waves of alien fighter ships, followed by refueling after every fourth stage for bonus points. Additional points can be scored by hitting the mothership, which occasionally appears at the top of the screen.
Controls are as follows: Caps Lock to move left, Ctrl to move right, Return to fire, S to turn sound on, and Q to turn sound off. You’ll earn an extra life once you hit 10,000 points.
