Mind-boggling simple. Stuff shoots at you. You shoot back. It's hard to get simpler than that. If I was in the right kind of mood, I'd write some sort of science-fiction flak whereby the little things that shoot at you are called "drones" or "seekers" or something ("Srones?" "Deekers?") and you're in a warp-drive spaceship bound for Planet Xandar to depose the evil Star Emperor Mungle the Snootful. Minimum Requirements: EGA, or VGA.
