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.

Love the Game, my style.
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.

一星都不想给,零蛋,地图设计纯达奋,不是爬管道就是挤缝,在岔路口完全分不清哪是主路哪是支路,每次又打怪又爬管道到支路尽头开箱子结果发现满满一箱乐色 优化方面更是灾难,开局不到20分钟刚进第二章就碰上BUG被关在电梯里出不去,高帧率推箱子只能往左右蹭,每次碰着箱子还得退游戏降帧率,不然箱子根本不动地方。还有双头boss战前的存档和载入点竟然不一样?小怪波次结束自动存档,加载点却是boss登场,中间存在空白时间,这期间捡的东西会全部丢失是真离谱。 怪物和战斗设计也是依托,怪物来回来去就几种,太空恐怖游戏结果80%时间都在拼近战,你家恐怖游戏跟变异怪物打回合制擂台是吧。那双头怪我就不提了,宝箱怪和飞头你告诉我怎么躲?命中率100%碰见必扣血还得准备QTE的粪怪设计纯反人类。最终boss法里斯一阶段就会个王八拳,和初见一模一样,二阶段俩技能复读,就这还外星病毒原型体,合着进化了个寂寞 资源管理也是,开局6个格子,商店分布极其不均,两组子弹两组药之后就剩俩格子,然后俩商店之间塞三四个信用点道具要么看着要么跑两趟,每次从商店出来还没有保存 剧情相当逆天,后期真相揭示男主感到愧疚我能理解,那前期面对一个害死自己多年搭档、刚从监房里救出来就坑自己、当面挖尸骨未寒的好兄弟芯片的八婆不一枪崩了还上去贴热脸? 最后DLC更是坨大的,竟然能把真结局塞到DLC里我是没想到的,剧情上直接推翻了本体结局把男主写死了,整个DLC剧情都是脑内幻觉。关卡内从开局开始堆怪,每波不少于四个,拿到锤子后,制作组更是把自己家亲戚全堆上来了,不会真以为那破锤子手感有多好吧
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.
Tipico juego 7/10, El combate medio repetitivo, pero la historia muy buena.
我就很喜欢这种血肉横飞的打击感,越暴力越血腥才越解压,我并不是剧情党,游戏讲的什么故事我也根本不在乎,用警棍把怪物打的东一块西一块,就是我想要的效果,这种游戏不好找了
How can they mess this beautiful game up with these horrendous fighting techniques... The melee encounters are the worst I have experienced in many years of gaming. What a shame to ruin a game that perfectly could have upgraded the Dead Space universe...
takie 6/10
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
