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 2,515 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.

Looks great, gameplay is fun. Got lost a few times.
The Callisto Protocol me dejó sensaciones bastante buenas, aunque no es un juego perfecto. Lo mejor es la atmósfera: el juego consigue transmitir mucha tensión, el diseño de sonido está muy bien hecho y visualmente luce genial. Hay momentos en los que de verdad sientes que estás atrapado en una prisión espacial donde todo quiere matarte. El combate, aunque al principio puede parecer raro, acaba siendo entretenido cuando te acostumbras a él. Dicho eso, también tiene cosas que no terminan de convencer. La historia me pareció correcta, pero nada especialmente memorable, y algunas partes se sienten un poco más guiadas de la cuenta. Además, hay momentos en los que da la impresión de que podría haber sido algo más ambicioso.

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.

Ich habe The Callisto Protocol komplett durchgezockt und vorneweg: Das Spiel hat mir richtig viel Spaß bereitet. Ja, natürlich gibt es Parallelen zu Dead Space – manche Dinge wurden übernommen, manches erinnert stark daran. Aber ganz ehrlich: Wurscht. So viele Spiele übernehmen Elemente aus anderen Titeln, und trotzdem können sie großartig sein und den Spieler begeistern. Genau das passiert hier. Ich möchte nicht verschweigen, dass das Spiel für mich sacke schwer war. Manchmal war ich so frustriert, dass ich es ausgeschaltet habe, um erstmal durchzuatmen. am Ende war es genau diese Mischung aus Herausforderung, Story und Atmosphäre, die mich drangehalten hat. Wer Dead Space gespielt hat und begeistert war, wird hier definitiv wieder abgeholt. Für mich war es ein intensives, spannendes und am Ende rundes Erlebnis.
No.
so so
I cant finish it because it keeps crashing but i have seen a full playthrough on youtube and it looks incredible, its not as good as its obvious insperation, Dead Space with the original 3 Dead Space games but its better than the remake of the first game. The graphics and visual designs look absolutly amazing and i wish i could continue the game.

#The Callisto Protocol draws attention with its atmosphere, but serious optimization issues and frequent FPS drops undermine the enjoyment of the game. It attempts a different combat system, yet in practice this system feels more like torture than fluid gameplay. Ultimately, technical problems and exhausting combat mechanics overshadow the game’s potential. #The Callisto Protocol atmosferiyle dikkat çekse de ciddi optimizasyon sorunları ve sık sık yaşanan FPS düşüşleri oyunun keyfini baltalıyor. Farklı bir combat sistemi denemesi var ancak pratikte bu sistem akıcı olmaktan çok işkenceye dönüşüyor. Sonuç olarak teknik problemler ve yorucu dövüş mekanikleri oyunun potansiyelini gölgede bırakıyor.
虽然是模仿,但整体游玩体验大于deadspace,该有的都有了,出色的动作系统弥补了怪物单一的特点,挺好玩的
Some spoilers below. Read on your own risk. In short this game is boring, repeatable, not scary and with bad writing. Calisto Protocol is basically a walk & smack simulator. Most of the time you'd walk from point A point B, with forced detours through points C, D, E, FML... Everytime the NPC is with you, they somehow end up either busy or split up with you, so you always have to fight alone... And there wouldn't be anything wrong with that, if not that it's because this game is just not built to have anybody helping you. It just has no mechanics that supports that. Same with fighting. Rinse and repeat the same thing, all the time for 10+ hours. You get new weapons, but they change almost anything. Meelee is superior for most of the times (exception is when you can't use it at all... for one type of enemy and end boss) and still it's junky and boring as ♥♥♥♥. Basically dodge, then attack, repeat 2-5 times. Sometimes shoot before they mutate, but it baerly works, because the game doesn't support leaving meelee (yes, you can't run away in a horror game). It's not really scary, and when you realise that most of the game is just scripted ilusion of tension, it becames not scary at all. The only moment I was under any stress was the last fight (because of the insta kill mechanics), and I'm not even a big horror fan, so I'm not hard to scare. The writing is basically a rip off of Dead Space mixed with Alien. The twist is not a twist. I was curious to see if there is any mystery behind what is happening, but it was so basic, I was dissapointed with the whole thing. Oh and a bonus thing: the game thinks you are an idiot. There are arrows left everywhere, to lead you. Not only that, there are messages on the walls, warning you of what's ahead, like "caution stairs" or "this way". If you are wondering who must have left them and if there is some mystrious explanation to them... there isn't. 5/10, not worth the time
