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.

“Iron Lung” is audacious and at times astonishingly boring. Still, it feels more enthusiastic and celebratory than many blockbuster adaptations built on safer math. Go to Full Review Emma Wolfe SpookyAstronauts 1h
4/10
It felt like it was kind of floundering, trying to include different aspects, [and] lore and then just filling up runtime with dead air. Go to Full Review Jeremy Jahns JeremyJahns.com 1h
There's some solid, creepy atmosphere and tone in here. Markiplier shows some talent here. Go to Full Review Nate Richard Collider 4h
6/10
The craftsmanship is there; with his directorial debut, Fischbach shows that he's more than just a YouTuber, and he can conjure up the same kinds of scares that make him scream as he's playing games. Go to Full Review Luis Pomales-Diaz Horror Press 4h
7/10
Soaked with all the gore, madness, and mystery of the likes of Event Horizon and Pandorum, Iron Lung is a worthy successor in the cosmic horror genre as it rises above its own problems. Go to Full Review Mark Dujsik Mark Reviews Movies 6h

sam 12m I can't wait till this movie is on streaming or wherever it ends up I want to watch it again See more Jenna 43m Went in totally blind and enjoyed myself! Very full of blood/gore/SFX but the team did a great job See more Lizz 1h FANTASTIC MOVIE!! For being the first ever movie Markiplier ever made, it absolutely blew me out of the water (or rather blood-) with how good it ended up being. 10/10, would absolutely watch 10 times in a row, I want the movie theater poster- See more Tiffany 2h SO amazing! So beautifully written, have been wanting to watch it again already. See more Keane N @Keaniegenie 2h It doesn’t good job of building up at times but it drags on long enough to get boring with an uneventful ending. See more derek 3h had promise but got lost in the blood and the script is straight outta a video game See more Read all reviews
