Buckle in and gear up for the classic galactic ride of your life. Far beyond known galaxies, the stars are scattered with precious crystals. As a renegade outer space prospector, your job is to scoop 'em up and bring 'em home. Just one problem: The brilliant glow of these gems attracts some of the universe's foulest pests. We call them nasties - and they're just that. So go ahead...zap the intergalactic vermin and cash in on the crystals. It's nasty-blastin' fun.
