You are a member of an underwater special forces unit and have been selected to infiltrate Madam Q's headquarters and stop her demented plans before she can destroy the world. You can find weapon power-ups and health along the way.
Bosses appear at the end of each level.
At the end, you face Madam Q, who has transformed herself into a giant floating disembodied head. I believe Atari Games only released this as a kit. The release date for the game was June, 1990. Technical 68000 processor. The board is populated with a slew of ROMs on a generic PCB with an architecture similar to that of Pit-Fighter .
