Comments on Iron Lung for Android

★★★★★ Roblox THAI · Feb 6, 2026

Very fun. This game is challenging and long, the claustrophobic ambience makes it even better. Recommend buying if you want a horror game that's actually hard.

★★★★★ Skyler Listman · Jan 27, 2026

This game is great I got the game on my PS5 and was talking about it with a friend and found out it came to mobile, so I absolutely had to get my hands on this game I beat the game for the first time ever yesterday on my PS5 now it's time for mobile I love the story and for all you knew folks if you put in the code SM8 into the computer in the iron lung/ submarine your in you get more lore about why you are there anyway love this game so excited for the movie

★★★★★ Isaiah Fajardo · Feb 8, 2026

It's a very interesting concept. I really like the idea that You are in an ocean of blood. I also really appreciate the creativity of the movement, and how you go about controlling your sub. The movie is pretty good, however it can feel boring at times. That is because, It's a slow burn type of adventure, and that's what gives the game & movie that feeling of tension. I HIGHLY recommend playing the game first, before seeing the movie though.

★★★★★ Gerald Washburn · May 11, 2026

Great game and great port, very well optimized. All I wish for is the cheats feature that's in all the other versions.

★★☆☆☆ Ryan H · Apr 4, 2026

Wanted to play this before I got to see the movie but sad to say this is easily one of the most overrated indie games I've ever played. Cool concept, extremely lackluster execution. This deserves a remake.

★☆☆☆☆ Dash Roy · Feb 14, 2026

You literally can't do anything that's in the PC version. Why can't you use cheats on mobile, but you can on pc??? The third image is impossible to get.
