About this app
Play the game the movie is based on!
Iron Lung is a short dread-driven submarine horror game from the developer of DUSK, Chop Goblins, and Squirrel Stapler, and being adapted to movie by Markiplier in 2026.
Set entirely within a claustrophobic one-man submarine nicknamed the "Iron Lung," you must blindly navigate an ocean of blood to take photographs of key locations, and hope whatever lives below doesn't find you.
There is only a single porthole on the sub, and it needs to be closed due to depth pressure, so you have to navigate purely via an incomplete map, proximity sensors, sound, and a primitive external camera which can be used to take the pictures you need to complete your mission, or to get a grainy low resolution visual of what's happening outside.
Success will require resourcefulness and patience.

Five-star share of ratings
80–89% five-star
Arithmetic on the stores' own published rating counts. It says nothing about why the ratings fall where they do.
In the package we scanned
No package has been scanned for this app, so nothing is published about what it ships. That is an absence of evidence about the app, not a finding about it.
