Submergent

Submergent is a short underwater exploration game in which you pilot a submarine through an Arctic cave system about 1,000 feet below sea level. As a member of an oceanography team, you must find the missing Alpha and Beta exploration teams, who have been gone for four days, and ensure their safe return.

Search the caves

You pilot the last remaining submarine, nicknamed “The Tin Can” because it is rusted and deteriorating. Sunlight does not reach the caves, so you use the submarine’s light to navigate the murky depths. Initial attempts to map the cave system have failed, leaving you to rely on the submarine’s old, unclear scanner.

You have a limited supply of flares to mark your route, and must use them sparingly. The game takes less than an hour to complete.
