Iron Lung

This is not an expedition. It's an execution.

A claustrophobic cosmic horror about a condemned prisoner descending into an alien ocean of blood, grappling with existential dread and the possibility of eldritch forces in a universe stripped of stars.

In a post-apocalyptic future where an event known as "The Quiet Rapture" caused all known stars and habitable planets in the universe to disappear, a convict is sent to search an ocean of blood discovered on a desolate moon, using a small submarine nicknamed the "Iron Lung".
