Prices
Each in the currency that store quoted — not converted: the gap between two rows is the publisher's pricing, not an exchange rate.
Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 3.43/day in the week to Aug 17 → 5.86/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 24 chart moves that followed a price cut of more than 20% went a median of 9 places towards #1, and the 2,404 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.

Reviews
An overrated cosmic horror experience. Nothing new, nothing scary, and tedious jump scares. There is no real gameplay, even though the graphics are decent enough. It’s a shame you never see anything other than the inside of a submarine. People who love this game have either never seen, read, or played good cosmic horror, or they’re just hyping it up because a YouTuber played it. You’re better off skipping it at this price; it shouldn't cost more than 2 euros.

It's the game Operation with a Science Fiction Horror setting. The atmosphere is great, but it's mostly staring at UI and carefully pressing directional buttons. I hope to get an Open-world RPG/FPS in this universe.
much better than the movie ill be real
Iron Lung is a very interesting and creative take on retro\VHS horror. As a player, you are essentially trapped in a single location and have to navigate almost blind, searching for points of interest on the map. It is a very interesting and elegant exercise in spatial navigation. The radar is extremely sensitive and responsive, so you always feel like you are in complete control. The game walks a very fine line between hardcore and casual. Yes, navigating through the narrow bottlenecks of the caves can be difficult, but the game autosaves regularly, so you are never thrown all the way back to the beginning. The same goes for the oxygen level, which obviously only decreases as you progress through the story. So while it creates a sense of tension, there is not really a strict time limit. The atmosphere is wonderfully minimalist. There may not be many of them, but the underwater photographs and your camera in general create some absolutely fantastic horror imagery. The film adaptation also turned out to be very, very good. Highly recommended to anyone who enjoys puzzle horror games.
le jeu est simple comme tout, il est court et peu profond mais il as une ambiance intéressante et un gameplay minimaliste. je vous conseille d'y jouer avec un copilote une feuille et un stylo et vous aurez une excellente soirée. bon jeu 16,9/20
Excelente juego de terror psicologico muy recomendado.
está genial, sólo hubiera deseado que durara más.
Hello everybody my name is Markiplier
There's no words for how good the atmosphere in this game is. How well it sets the feeling of being trapped in a place of no return. It's so good. Even when the game is almost nothing, the atmosphere carries it like a horse carrying a king. Really great.
