Underwater — immerse yourself in the impasse of the underwater world. Go in the person of an unknown prisoner to an underwater prison, where dangerous mutants roam, now only reminiscent of the past human life. You have to show all your ingenuity to get out of the underwater camera and not become the food of a huge ugly monster. Find out what happened in the underwater complex and who the main character really is. Whether you can get out of the underwater grave or not is up to you, no one will come to the rescue. Welcome to world of underwater world.
