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.

PROJECT DETAILS:
Markiplier is working with YouTube to distribute the film digitally, giving fans the opportunity to purchase the film exclusively through YouTube movies later this month. (5/17/26)
Though the original intention was to release the movie to 50 to 100 theaters, Markiplier has revealed that most of the major theater chains have picked up his movie and it's now currently set to release to almost 1800 theaters (according to the official site). (12/12/25)
Markiplier is self-distributing the movie and working directly with independent theaters across the country. The plan is to release the film on January 30th 2026 to a goal of 50 to 100 independent theaters. Mark was quoted saying: "They said it shouldn’t be done. Not that it couldn’t be done, people have made movies before, just that it would be ‘woefully unwise’ to tackle writing, directing, acting and editing a movie myself. Showed them. My bathroom might be a render farm now but I can’t wait for people to see the blood, sweat, blood, tears, blood and blood that went into this movie from everyone involved." (12/5/25)
Filmed in Austin, TX.
The movie reportedly holds the "world record for most blood in a horror movie. Or any movie for that matter."
Content creator Mark Fischbach AKA Markiplier writes, directs, produces and stars in this film.
The original game's creator David Szymanski is said to be working closely the filmmakers.
Based on the 2022 immersive submarine horror game with the same name.
