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.

Real cool game, would recommend Makes you VERY aware of the fact you dont have a good sense of direction Nice psychological pressure if you put yourself in the mood (lights off, headphones, no other distraction)
SO PEAK or ig DEEP? No spoilers in here but Peak
We’re going into the Blood Ocean, and honestly, just hearing the word “ocean” was enough to trigger my thalassophobia. Add being trapped in a confined submarine with nowhere to go, deep beneath the ocean, and you’ve got pure terror. The gameplay mechanics were a little difficult to understand at first, but once you get used to them, they work really well. The scares and sound design are fantastic, and the atmosphere genuinely makes you feel trapped beneath the Blood Ocean. This is an incredible horror game that absolutely delivers. Amazing job, David Szymanski! Overall, I'd give Iron Lung a solid 9 out of 10 Blood Oceans GAMEPLAY (The game starts at 31:34) https://www.youtube.com/watch?v=qC5BFNbGiEk&t=15s

ironing my lung to ts rn
Iron Lung is one of those games that you just wish were longer. The concept of the game is original and inspiring, combining themes of horror, mystery and obscurity is ways rarely seen. The game manages to capture the essence of feeling like you're all alone, but at the same time as feeling like you are being watched by thousands of eyes, glaring terrifyingly deep into your soul with menacing pupils; reminiscent of cold, cracked hands pressing on the back of your shoulders, but no one is there... you are alone. The pillars of which this game was built must have constituted some great design philosophies. Being able to create such a dark and alien atmosphere with limited visual queues (i.e image scanning system on the submarine) is something I feel is not easily achieved. This is of course a tip of the hat towards incredibly immersive sound design (Creaking metal, deep, monstrous bellows and distant, incomprehensible screeches). The details that are apparent are purposeful, but this is an example of "Less is more". What I mean by this is that what the game gives you plays on your imagination and scepticism. It does not spoon feed you every single detail about what is happening, or what an extended plot might be. Through intelligent sound design and writing, it leaves you to your own interpretations and theories about any form of extended plot beyond the realm of what this game 'explicitly' provides. Regarding actual gameplay mechanics, the navigation for the submarine is based on an x,y,a coordination model (not the typical visual aspect of a submarine literally moving through water or other liquid in real-time); It's genius. It provides the player with a sense of movement and progression, while also giving the impression that they are a sitting duck in an ocean of black and unknown. Iron Lung is an experience that will stay with me for the rest of my life. Simple and humble upon first inspection, but a universe which I feel could descend even further into the depths of its own mysterious, rusted bloodbath. 10/10
Hours dont count cus i finished it on my school laptop but god is this game fantastic. I'm glad the movie lived up to it's legacy.
İki titriyon bişey olmuyo çok çok en falza sesten koruyon öyle
