User Summary A side-scrolling shoot'em up. Defeat ten waves of aliens in order to proceed to the next level. The back of the box says: "Fly across an alien planet inhabited by some really nasty creatures. Battle against the devious changing tactics of ten swarms of nasties. Watch out for swarming spiders, banging bangers, bashing bashers, spores, swoopers, darts, zappers and sly baiters."
