The stars are gone. The planets have disappeared. Only individuals aboard space stations or starships were left to give the end a name -- The Quiet Rapture. After decades of decay and crumbling infrastructure, the Consolidation of Iron has made a discovery on a barren moon designated AT-5. An ocean of blood. Hoping to discover desperately needed resources they immediately launch an expedition. A submarine is crafted and a convict is welded inside. Due to the pressure and depth of the ocean the forward viewport has been encased in metal. If successful, they will earn their freedom. If not, another will follow. This will be the 13th expedition.

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.
