Iron Lung

After the 'Silent Ecstasy' event, all stars and habitable planets in the universe vanished, leaving humanity clinging to life in a crumbling space station. Prisoner Simon, sentenced to death, is offered a deal: pilot a decrepit submarine nicknamed 'Iron Lung' to the Blood Ocean on the barren moon AT-5, find the lost planets and resources, and earn his freedom. The submarine has no windows, relying solely on external cameras and sonar for navigation. Simon ventures through the endless red deep, with camera feeds flickering in and out and sonar picking up mysterious knocking sounds. Water begins to seep into the hull, red liquid flooding in, while an unknown presence watches his every move from the depths, enveloping him in solitude and terror.
