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.
Too few observations to say whether a discount moves this store's chart at all: across the last 30 days Steam · Top Sellers · Poland has just 18 day-to-day chart moves that followed a price cut, against 2,498 that did not. We are publishing the count instead of a direction — 20 is the fewest we will draw a conclusion from, and price collection outside the United States began on 6 August 2026.
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.

Reviews
The graphics are nice, some of the mocap expressions are a little weird. The combat is okay but it does get a little repetitive after awhile. The story so far is serviceable but I don't think I'll finish it. What really turned me off is I'm just tired of crawling through vents and squeezing through sections of pipe. Here and there is one thing but I feel like 80% of the last hour I played was crawling through damn vents. It's like having to slog through a filler episode of a TV show, just to drag out the story.
Отличный аналог Dead Space, но упор тут больше в экшен, чем в хоррор. В DLC решили всё же дожать атмосферу, но только до середины. Оптимизации чуть не хватает и с FSR играть больно поэтому 8/10

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.

Congrats! This is the buggiest thing i've ever played! Not in the constant, small issues sense. But in the "I just rebooted the game and lost 6 hours of progress because my saves vanished" Sense. Incredible. The self deleting game. I got about 6.5 hours in before this happened. And overall, The callisto protocol is a largely vapid, trite attempt at a horror game that plays far too much into over-the-top visuals and voice acting for it's own good (I normally am very sensitive to medical horror but found myself just kinda,.. laughing through the first and second chapters), but a somewhat decent zombie shooter after that. Throwing opponents into spikes and pits, or stringing together combos with a mix of weapons isn't bad once you get the hang of it. You just have to really ignore the game trying to be taken seriously, and lean into the absurdity of the stomp and the grip abilities. The game has an EULA that states it collects user data including gender and location and age. It is single player. Gross! Icky! I got this for free, but it was with the purchase of a 350$ graphics card a few years back. so that's worth noting. I'm going easy here. Easy pass. Pick up Titanfall as a sci-fi shooter and something else for horror.
氛围营造这游戏是顶级的,故事架构非常不错。剧情方面能看出来是想做续作的,世界观也就透露了一小部分,狱长背后的组织根本就没交代,因为发售暴死,项目被砍,所以让主角死了,阴谋让马勒传给达妮强行完结了,原先剧情肯定不是这样的,感觉是想来三部曲。 玩过所有游戏优化最烂的没有之一,关光追最高300帧最低low帧能掉到40,dlc个别场景显卡风扇时而起飞。。 双头人没有弹药=无解,躲避后硬直时间很长没有任何近战操作空间,就算你警棍挥出去后你会发现人家自带空气墙🤣 回血时间极长,每一个刷怪区域意味着你需要一管血清干净,否则只有死,没有任何加血机会。 总之还是有点可惜,玩过的第三个烂尾游戏,第一个cod幽灵,第二个往日不再,这个算第三个。
[h1] DEADFLOP EN PRISON [/h1] Pas envie de m'attarder dans mon évaluation car le jeu n'en vaut pas la peine, donc ça vas être une liste: [h3] TLDR :Achetez en promotion [/h3] (et si vous êtes TRES nostalgique des Dead Space) [list] [*]Graphismes magnifiques [*]Environnement corrects et "variés" (dans la mesure du possible du le contexte du jeu) [*]Histoire déjà vu milles fois qui tient sur un post it [*]Système de combat plutôt fun malgré la mécanique de mutation qui est parfois injuste [*]Roster d'ennemis NUL, vous allez affronter Zombie Mutant et ses quelques variantes déjà vu dans 10 autres jeux du style, et 1 où 2 autres trucs différents mais seulement très succinctement [*]Durée de vie de 10h en ligne droite et jusqu'à 15h si on prend vraaaiiiment le temps [/list] Vraiment pas sûr de la plus value de mettre dans les principaux personnages des acteur connus, tout le monde s'en fout et je peut pas m'empêcher de me dire que c'est de l'argent qui aurais servis à améliorer le jeux, aux détriment de ........ bah absolument rien
В общем на скидках норм
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
Tipico juego 7/10, El combate medio repetitivo, pero la historia muy buena.
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.
