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".

Why it matters

A claustrophobic descent into cosmic dread that mashes deep-sea terror with post-apocalyptic isolation — but struggles to sustain its eerie tension.

  • Submerged horror with a twist: a convict trapped in a blood ocean, welding together body horror and sci-fi decay.
  • Fans of slow-burn atmospheric dread may appreciate the moody, suffocating design and unsettling hallucinations.
  • The creature and cosmic mystery tease big scares but arrive fleetingly, leaving a gap between build-up and payoff.
  • Best for viewers who savor mood and concept over clear narrative or traditional scares, especially those familiar with the game source material.
