You're in command of a submarine navigating enemy territory. Rely on your expertise, radar, and a bit of luck to destroy enemy vessels. With eight difficulty levels, there's plenty to learn as you begin to manage your fuel, torpedoes, radar, and awareness of enemy forces while evading depth charges that become more frequent as the challenge increases. You're allowed to launch up to two torpedoes simultaneously. As enemy convoys pass by your periscope, try to sink as many ships as possible. The periscope offers a 360-degree view, letting you scan both the distant horizon and the area near your sub. Some ships travel at different speeds, and one moves so quickly that the only way to target it is by using radar tracking rather than visual sighting. This game was never released under any title by Atari. It was exclusive to Sears.
