A short horror game where you pilot a tiny submarine through an ocean of blood on an alien moon.
Modeled estimate, not a reported figure. How we estimate →
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 2,419 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.

Add-ons
Each DLC is estimated with the same model as a game, then summed — a modeled figure, not reported DLC sales.
Sums Steam only; PlayStation, GOG, Nintendo publish no volume signal, so the true total is higher by an unknown amount.

MUITO BOM!!!!! Sinceramente, no inicio achei que o jogo seria maçante e que eu enjoaria em pouco tempo. Passei uns dias para entender como funcionava a questão das coordenadas e ficava só batendo o submarino. Depois que eu revi o material escolar do 7 ano sobre coordenadas, o jogo ficou babinha. Apesar de que quando você pega o jeito nas mecânicas, Iron Lung não deixa de ser interessante até o final. Toda a questão com as criaturas, as alucinações e a estrutura se enchendo de sangue de acordo com o quão próximo você está do final, deixam tudo com um gostinho amargo de que realmente não tem como sair do submarino vivo e são, você apenas aceita a realidade. Fico feliz que Markiplier fez o filme inspirado, pq o conceito é realmente diferente e muito legal de se explorar. Concluindo, jogaço 👏👏👏👏👏
An ocean of blood and mysteries...
We are one in the blood Simon... Open your eyes

Court et très sympa. L'histoire tient à pas grand chose, il s'agit plutôt d'un lore très peu mis en avant, mais après avoir fini le jeu j'y suis retourné justement pour m'amuser à chercher un peu d'explication avec les outils dispos dans le jeu.
i do like following coordinates
