Game developed by Data Age and distributed by Gameworld in 1983.
The player is trapped in a damaged nuclear submarine that has begun to embark water inside.
It is therefore necessary to escape by climbing the various levels of the submarine one at a time.
Each floor has two keys that must be collected to unlock the elevator which allows you to move to the next level within a time limit; if this limit is exceeded, the floor will flood and it will no longer be possible to escape.
Due to the crash, the torpedoes on board the submarine become free and begin to wander on the floor while the boat continues to shake. The player will then have to jump over all the torpedoes he encounters along the way, otherwise he will suffer a momentary stun and lose precious time.
