About Iron Lung

Explore Iron Lung, a claustrophobic horror submarine sim! In this immersive encounter, use tools to navigate a blood ocean, take creepy images, and survive unknown predators.

Iron Lung: Immerse in Blood Ocean Silence!

Iron Lung is a short, atmospheric horror simulation game that will test your nerves. You're in a tight metal submarine in a human blood ocean on AT-5, a mystery moon. You, a condemned prisoner released to explore these frightening depths, are humanity's final hope after the "Quiet Rapture" erased all planets and stars. Fear isn't about combat, but about limited visibility and the frightening expectation of the unseen.

How to Play

You must navigate blindly! Your submarine has no windows, so you must use basic instruments, a static map, and coordinates to navigate.

Use the external camera for blurry black-and-white photos. There's a delay, and you never know what monsters will be found.
Avoid crashes by regularly checking your vessel's coordinates against the trench map.
Survival requires monitoring oxygen and hull integrity.

Nighttime hazards are only alerted by creaking metal and proximity detectors.

Game Controls

Iron Lung involves manipulating your submarine's key systems.
Your inputs (presumably mouse and keyboard, but keys aren't indicated) will control the instruments, map, and external camera.
Compare coordinates and manage sub functions.

Tips for Strategy

Iron Lung survival requires precision. Prioritize vessel management and check coordinates against the map to avoid collisions. Every creak and warning in the spooky sound design reveals your fate or escape. Remember that the external camera is your sole "eyes," yet its delayed, distorted photos make every photo a risk. Luck, you'll need it!
