It's a rather novel shoot-'em-up from Bio 100%. You control a battleship dropping depth charges on enemy submarines, and then it switches to an air assault for the next level. There's power-ups and a fairly wide variety of enemies.

Bio 100%'s website reveals your battleship eventually goes into outer space and fights aliens. Oh hell yes.
