In this horizontal scrolling shoot'em up. The player controls a submarine that can shoot torpedoes forwards. The gameplay involves navigating "past underwater mountains and through labyrinthine passages while avoiding webs of explosive mines that rise from the sea bottom. Additional dangers include mine-dropping ships, enemy attack stations, falling stalactites, and deadly lasers—any of which could keep you from your ultimate goal: destruction of the incredibly powerful nuclear reactor at the end of the undersea course."
Written by Wayne Westmoreland and Terry Gilman, and released in 1982 by Adventure International.
