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 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,402 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.

Wow this was so cool they should make a movie of this.
Short interesting game where you drive a submarine through a blood ocean. I like the atmosphere.
Good game but I don't like how the game gives you 0 indication where any of the POIs are outside of the map, you NEED to photograph all of them to get the ending and they're black icons on a dark background. I had to hover my mouse over the entire map just to see where they were and by the end I was confused because I wasn't getting the ending and it's because I missed a POI near the start I straight up didn't see, and had to backtrack all the way which annoyed me a lot. Other than that it's great

navegando por los mares de bolivia the game
I really wish i could have played this game blind as i think it would have drastically improved my experience with it. I can't exactly remember when i first saw Mark's iron lung playthrough but it stuck with me very vividly so naturally i went to see the movie. I really liked what he did with the ip and have always liked the worldbuilding of Iron lung anyways, especially everything surrounding the quiet rapture. So I finally decided to play the game for myself, even moreso due to having beaten 'Mole' recently (an indie horror masterpiece that feels similar to iron lung but better). Despite being an unfortunately non-blind playthrough the game still pleasantly suprised me with one thing standing out in particular; the excellent sound design. I'm not joking when i say that the SFX are literally half of the experience here so you owe it to yourself to either play this game on a great big stereo or with some top of the line headphones. The sound design pairs so well with the restricted senses and claustrophobic environment to create a highly immersive experience that stimulates paranoia. The simple movement mechanics might seem boring at first but they feel like a breath of fresh air leading to innovative and suprisingly fun gameplay. It doesn't overstay its welcome and is perfectly paced in my opinion, an hour is exactly the right amount of time to get familiar with the systems before getting burnt out on them. A short and cheap experience that's worth playing for people who love excellent atmosphere and worldbuilding.

Heard a lot about Iron Lung before the movie came out so I was determined to play it. It was short and sweet, an atmospheric dive into a sea of blood, which made you leave with more questions than answers. It does a lot with very little, with almost all the tension and scares being from the audio surrounding the submarine. With that i can see it not being for everyone, but with the game being $8 and can be beaten in less than an hour, its worth a try.
