Better known as Chaos Engine, this game was an Amiga classic, and that's probably the reason why I bought it for the Genesis. Of course it's nice not to have to wait for the damn game to load off a floppy disk like I did with my Amiga, but the downside is the music kinda sucks in comparison. Oh well, I really am not too crazy about this game anyway. It's OK--kind of like a sci-fi Gauntlet--but nothing I play too often. Run around various levels (top-down view) blasting enemies and collecting keys, coins, and power-ups, progress to the next stage. Can play two players simultaneously.
