Description

Iron Lung is a short dread-driven submarine horror game from the developer of DUSK, The Moon Sliver, and Squirrel Stapler.

 

FEATURES

  • Experimental minimalist gameplay, where your senses are limited and anything could be lurking around you 
  • Glimpse your surroundings through the lens of a grainy still camera and navigate using an incomplete satellite map and proximity sensors 
  • Horror based around building dread and paranoia 
  • Original soundtrack inspired by the work of Aubrey Hodges (Doom 64) 
  • A short experience intended to be finished in under an hour


THE GAMEPLAY

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. 

THE STORY

Decades ago, every known star and habitable planet mysteriously vanished, along with whatever and whoever happened to be on them, leaving behind an empty universe of asteroids and lifeless moons where the only remnants of humanity are those who were on space stations or starships at the time. With supplies gradually dwindling and infrastructure falling into disrepair, the survivors have spent the subsequent years frantically searching for any trace of remaining natural resources. Up until now they have been unsuccessful... 

Then, a mysterious anomaly known as a Blood Ocean (which is exactly what it sounds like) was discovered on an otherwise barren moon. It's not the first Blood Ocean found since the vanishing, but initial scans show a collection of potentially useful anomalous locations in a deep undersea (underblood?) trench that require further investigation. 

And you're the unlucky sap who gets to investigate, in an aging submarine cobbled together from rusty space station parts. 

Find your way to the marked locations, photograph whatever you find there, and try to finish before the sub collapses around you... or you're discovered by whatever lurks in the blood...

Genius

It will take a few tries to beat, but after you figure out how to properly navigate without crashing it can be done in one sitting, which is quite befitting for the plot. The music and sound design are most excellent and really add to an already tense and claustrophobic experience. This is definitely a game that is best enjoyed when going in blind (you figure out everything yourself). If you like horror games that include a little brain work on your part, this game is worth your money full price, and you would be a fool not to pick it up when its on sale.

Good atmoshpere that plays on ur psyche

4/5 7/10 Really great short game, the suspense and dread and atmosphere all tied in well and you can easily imagine what it would feel like being alone underwater like that, especially the further in you get. I always wanted to play this game when I was on the other platform and was sad I never got around to it before I left, so I was super glad to see it arrive here. It can be a little hard to figure out how to steer and what to do. Just open your map, look at the dots and coordinates, and use your navigation to steer toward it, or other interesting locations that might hold optional stuff to see. But you dont have be a pro at reading the navigation system, its straight forward if you just take a few moments to read the numbers and pair them with your map. It gets tight in some places where you have to navigate close to the edges and not fall off, pay attention to the warning beeps and look at the x and y position of where you want to be, then aim for that while trying not to panic and ignoring the sounds outside your pod :o The whole steering without sight gets to ur psyche after a while, at least it did for me, you start to feel more and more alone and claustrphobic the further in you get. Loved it! The terminal has lore you can look up if you want to know more about it all, try to type Some of the interesting words on the first screen and see where that gets you. One of the optional sights has another keyword you can type in. A movie was made of this game, featuring Markiplier! Made with a budget of just 3 million and already earned ~20 million in just a few days! If Szymanski and Klubnika were ever in a room together, oh boy! Ty for the bonus game SpinNShoot :D Its added as a goodie in one of the folders with bonus stuff, found it while searching for naughty analytic stuff which this game has none of, ty for that, and the extra game :D Game save is in the main game folder in a folder named Save, file called progress. Would really love to see Pony Factory and especially Secret Agent Wizard Boy on GOG too pls! Would also love to see a bigger and longer version of this game. This was too short ;( Worth full price. 🐧 Arch Linux EndeavourOS

there's something there!

ok, now this game is a) very short, b) very atmospheric, and c) definitely worth your time if you're a fan of unconventional horror stories it puts you into an "iron lung", a submarine without a window, and sends you to check several places at the bottom of a sea of blood - so you have to navigate only using your rough map and controls showing you where you the game has no tutorial so you have to find out for yourself how it works (it took me a while... but I got it eventually) and contains jumpscares, but a horror fan shouldn't be worried I guess PS: a movie based on the game should hit theaters in January 2026

What a masterpiece!

Now is the time to pick this game up and finding out what a masterpiece it is! I remember seeing one of my fav YouTubers playing this in the past and I was so terrified! And now he is making a movie out of it! Amazing! Def worth a purchase!
