Prices
Each in the currency that store quoted — not converted: the gap between two rows is the publisher's pricing, not an exchange rate.
14 of 15 markets; the rest we haven't asked for this title, not markets where it is unavailable.
Availability
We put this game to every storefront we collect. A market that answered not sold has told us something about the game; a market we never asked has not, and the two are never drawn the same.
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.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 23 chart moves that followed a price cut of more than 20% went a median of 14 places towards #1, and the 2,420 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.

jogo excelente
I got this game for free on Epic Games a while ago and barely touched it. Then Steam syndrome kicked in, so naturally I bought it again on Steam. Well well well I just finished the game and. ♥♥♥♥♥♥♥♥♥, this game was insane. I genuinely don't understand why this game is so underrated and why it got so much hate. I had a really good time with it. Pros - The graphics are absolutely insane. The game looks so good that I showed some screenshots to friends who had never heard of it, and they thought I was showing them a movie. - The cinematics are gorgeous. Some scenes genuinely look like pre-rendered movie scenes. - And it is not just the cinematics. The actual gameplay looks incredible too, especially with max settings and good hardware. - The gameplay and combat mechanics feel smooth and satisfying. - The environment and world design are excellent. The whole place feels dark, disgusting, and hostile in exactly the way a horror game should. - The music and sound design are fantastic. - The game actually managed to scare me a few times. The jump scares were good, but the sound design was sometimes even scarier. - Playing with a headset makes a huge difference. There is one moment where Elias calls Jacob's name and you hear someone whispering “Jacob” directly in your ear. Holy ♥♥♥♥. I immediately started looking around like an idiot, even though I knew it was probably all in my head. Performance was also very good after fixing a small issue. I had some minor performance problems at first, but a simple mod fixed them. After that, I was playing in 4K, max settings, at well over 70-80 FPS, with no noticeable stuttering or lag. Cons - The sprinting system. Why do I have to hold Shift the entire time? Please give me a toggle. My finger does not need a workout just because Jacob wants to run. For crouch? Np u can toggle but why not sprint man? - Enemy variety is limited. You fight a lot of the same types of enemies, and I really wish there were more creatures and monsters. - Sometimes I got a black screen when launching the game, and I had to close it and start it again. - A few minor performance issues before installing the mod. Overall, 7.3/10. If you like horror games, especially games similar to Dead Space, I absolutely recommend giving this one a chance. It is usually available for a very low price during sales, so there is really not much to lose. I actually played a little bit of Dead Space before and it did not really grab me. After playing The Callisto Protocol, though, I think I am going to give Dead Space another chance and see if I appreciate it more this time. Seriously, don't let the mixed reviews scare you away from this game. It's gorgeous, atmospheric, creepy, and a lot of fun.

14 on sale1 answered “not sold”0 we did not ask
The 1 “not sold” market is read from the Steam price pass of Aug 27: that day the store answered for this game elsewhere and gave no price there. The 14 priced markets are the same rows as the table above — each the latest price we hold, dated here when it is older than that pass. The 0 marked “not asked” were not put to this store at all — either it has no storefront there or we do not collect it yet, and neither is a statement about the game. A refusal is a refusal on one day; a store can list a title again tomorrow.

Had a lot of fun playing this game. Played using an xbox controller. Nice mix of combat, having to stealth and using environment to kill enemies. Some jump scares but nothing to OTT. Only gripe about the game is the weapon change system, I would have preferred it if you could assign a weapon to each of the directional arrows on the controller.
Me ha gustado la historia y el juego en general. Hay un par de detallitos que son para darles en todo lo alto, sobre todo los eventos de script que hacen que atravieses personajes, enemigos o que éstos sean invulnerables, lo que arruina la suspensión de incredulidad. No sé en qué gastaron los 150 M que he oído este juego. No lo machaco porque me parece un Dead Space evolucionado y eso es bueno.
The Callisto Protocol é um 10/10 absoluto. Puro suco do terror espacial na mesma pegada de Dead Space. Injustiçado demais pelo hate da galera e pelas baixas vendas, o que infelizmente matou as chances de uma sequência. Jogaço! 🎮💀
kapitalna grafika,czujesz jakbyś oglądał film w 8k albo sam w nim grał
Bom jogo. Dá náuseas.
Tipico juego 7/10, El combate medio repetitivo, pero la historia muy buena.
eh it's okay, finished it without experiencing bugs that being said I didn't go hunting for bugs or attempting to break the game to say look bugs, patches fixed the frame hitches and other unreal engine nonsense, I wouldn't call the game awesome or worth it at full price.. I mean it's one of those stories that you can see the ending from a mile away, I basically guess how the game will end at the very start and was unfortunatly proven correct. for story I give it a meh, and for gameplay I give it an okay. I give it a thumbs up because they atleast fixed the mechanical issues.
nice game, still not finish the full story but gameplay is fun. good for people searching some difficulties. gameplay ways is a little like the last of us 1, so relaly nice. can be a little heavy during movement but honestly when you imerge in the game it's not that bad
