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 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 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.
About
The Office Killer is a 1-3 player online co-op survival horror game. As a spy, your main goal is to complete the file transfer process containing the office's dark secrets while monitoring live surveillance camera footage. Can you survive the entire night or will you get caught by the killer?

Every report you send using the cameras increases the transfer by 1%. There is also another data coming from the data center... This will also increase the transfer. This may spontaneously be interrupted, and in these situations, you will need to leave your computer.
Track the killer's footsteps using the cameras and prevent them from attacking you. Some criminals might kill you through the vent... Don't trust anybody...
Featuring one cinematic, story-connected good ending, and different bad outcomes when the operation fails.

You and your team are a group of spies, experts in the field of cyber security, who are capable of cracking high-security systems for the SolidSpy organization. Your identities are kept secret, and you are responsible for night operations. One day, a person with the code name Anonymous contacts you via email, claiming that a company is conducting dark business in its offices. After a long investigation by detective teams, you learn that one of the suspects from a murder case that was closed in previous years due to insufficient evidence is now working at this company. You decide to quietly infiltrate the office at night to uncover all its secrets.
The company you are infiltrating is named CYPERIX, and since 2002, they have been involved in the production of components and software development for realistic human models. By using various components in their models, they aim to create advanced AI human-like robots that will be beneficial to people and be used in modern society.
This project seems beneficial to humanity, but don't get excited just yet. A killer lives in an isolated room in a data center within the CYPERIX office and is responsible for the models' security. He works the night shift, and no one knows what he does at night. According to rumors about the office, people passing by the building at night frequently complain to the police about hearing numerous footsteps, which disturbs them.

I played this game with two of my friends and we ended up having way more fun than we expected. This game is way too underrated for what it offers. Co-op horror in this niche barely has any interesting releases that are ACTUAL fun. The unpredictable moments, atmosphere and tension make it incredibly replayable. Every run is different and that makes it very interesting. As others have said, if you liked Welcome to the Game 2 / Dead Signal and wanted to find a multiplayer experience to try out with your friends, well, you have found it! I'd also like to use this opportunity to thank the developer for being so kind, responsive and genuinely listening to the community. You can really feel the passion behind this project, and we truly appreciate it. Big thanks to the dev! We're excited to keep playing and supporting the game as it grows!
Güzel oyun, 2 arkadaşımla oynuyoruz developer eve baklava yolladı.

very good game
Really great horror multiplayer game i had really fun playing it with my friend and we made good memories its really fun and has a lot of potential
such a great game honestly, my friends and i have been playing it ever since the release and we love the updates and everything, you did a great job and im sure it will have a big growth :3
Fun co-op anomaly game, would love to have the option to turn the killer off (insta kill after one down and has some glitchy teleporting at times that can end a run in the blink of an eye, which really puts me off playing it repeatedly and was almost enough to put me in refund territory) The normal mini games and invaders are interesting and you can defend yourself against them but they can still down you but dont seem to produce the insta kill the "killer" does, anomalies are well done, reporting is a bit weird to get used to due to wording (suspicious evidence rather than just extra object, and intruder and stalker are different things but some invaders are saboteurs depending on location so it gets a bit confusing) But overall its good and I would recommend and just hope some improvements and adjustable difficulty options are added to make it more fun and less irritating lol in the long run.
Just finished playing this game for about 1.5 hours and it is AWESOME! I played solo and It's similar to an anomaly game but with a sprinkle of Phasmaphobia. The jumpscares were perfectly timed. GGs to the dev for a great game!

NOT YOUR AVERAGE ANOMALY GAME! I was thankfully given early access to this game and I must say this is a game that I thoroughly enjoy! Without giving spoilers, it takes some brain usage and learning of the mechanics to thrive in it. If you enjoy games like WTTG or Dead Signal, then you would definitely love this game! With increasing difficulty making the game much harder and more complex, it's definitely a great experience!
Very enjoyable, fun and challenging game. definitely recommend
