Thought your H89 or H19 couldn't do this? Think again. Your screen becomes a fast-action video game. Alien creatures try to land; you hold them off with your space cannon as you dodge their bombs. Play it as it comes, or customize with 23 user-variable parameters to increase the challenge; even design your own graphics. By Robert Wesson. Requires H89 or H19.
