Two detectives, one deadly experiment, a race against time. Each player only has one half of the puzzle. In this 2-player co-op puzzle game you can survive the parallel experiment only by working together.

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.
Reviews, worldwide (the counter carries no country): 0.71/day in the week to Sep 7 → 0.71/day in the week after.
Reviews, worldwide (the counter carries no country): 0.86/day in the week to Jul 25 → 2/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 25 chart moves that followed a price cut of more than 20% went a median of 10 places towards #1, and the 2,413 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
IMPORTANT: "Parallel Experiment" is a 2-player cooperative puzzle game with escape room-like elements. Each player must have their own copy on either mobile, tablet, PC or Mac (cross-platform play is supported).
In the game players take on the roles of two detectives who are often separated, each with different clues, and must work together to solve puzzles. Internet connection and voice communication are essential. Need a Player Two? Join our community on Discord! Find the link on the side of our Steam page.
Parallel Experiment is a noir-inspired adventure with a comic book art style, featuring detectives Ally and Old Dog. While following the trail of the dangerous Cryptic Killer, they suddenly become his targets and are now unwilling participants in his twisted experiment.
This is the second standalone chapter in the “Cryptic Killer” cooperative point-and-click puzzle game series. You can play Unboxing the Cryptic Killer first, if you want to learn more about our detectives and their nemesis, but Parallel Experiment can be enjoyed without prior knowledge.
In Parallel Experiment, players must rely on their communication skills as they’re separated and must each discover unique clues that are vital for solving puzzles on the other end. Teamwork is essential to crack the Cryptic Killer’s codes.
There are over 80 puzzles striking the perfect balance between challenging yet fair. But you're not facing them on your own! Communicate with your partner on how to best proceed, solve a puzzle on your end that unlocks the next step for them and discover a wide variety of puzzles from redirecting water flows, finding computer passwords and unlocking intricate locks, to deciphering cryptic ciphers, soldering electronic components, and even waking up a drunk!
Looking for a break from the main investigation? Dive into a variety of retro-inspired mini-games designed with a fresh cooperative twist. Challenge each other to darts, Three in a Row, Match Three, Claw Machine, Push and Pull, and more. Think you know these classics? We’ve reinvented them for a whole new co-op experience
Uncover vital clues through collaborative conversations. NPCs respond dynamically to each player, offering new layers of interaction that only teamwork can unravel. Some conversations are puzzles in themselves that you need to solve together!
Our love for comic books shines in Parallel Experiment. Every cutscene is presented as a beautifully crafted comic book page, immersing you in a gripping, noir-inspired narrative.
How many pages did we create to tell the story? Almost 100 pages! Even we were surprised by how much it took, but every panel was worth it to deliver a story that keeps you on edge until the very last frame.
Every detective needs a notebook. In Parallel Experiment, players can jot down notes, sketch solutions, and interact with the environment in creative ways. But we all know what you're going to draw first…
This is a key feature? Yes. Yes, it is.
Each level will have some way for players to annoy their co-op partner: knock on a window to distract them, poke them, make their screens shake. You already know you'll be doing this just by reading it, right?
Parallel Experiment has a variety of mind-twisting challenges that push the boundaries of cooperative puzzle design, offering situations never seen before in other games.

super gra
Fena değildi. Bazı puzzlelar eksik hissettirdi ama güzeldi. Ben bu eleven puzzles oyunlarını genel seviyorum ve sonrakini bekliyorum. Bence Unboxing the Cryptic Killer bundan daha güzeldi. Yine de tavsiye ederim. 2 player point and click puzzle bence çok güzel bir konsept

解密过程还是不错,可圈可点,两个侦探纯无能的丈夫,在前传到目前的剧情里都一直被抓,剧情感觉不如ai,对解密的可玩性简直毫无影响,最后感谢我的神秘游戏伙伴陪我通关,over
[h2] It's incredible!!!! [/h2] Worth the money and hours I've spent on this game, impressive to say that an indie team pulled this off.
跟前两部比,剧情更加丰富,场景更多元化,不过游戏时间太长,玩的有些累,解密的环节还是一如既往的好,里面有一些益智小游戏可以玩,没通关也不会影响游戏进度,增加了游戏的可玩性。前两部有酣畅淋漓、很惊喜的感觉,这种纯双人合作解谜游戏真的很少了,玩的这么多里面,这个系列是最喜欢的,以为第三部跟第二部的时间差不多,玩到中途真的震惊这次的体量,不知道有没有下一部,期待作者有更惊喜的作品。

Intrigante
好遊戲,這系列從Unsolved Case 玩到 Unboxing the Cryptic Killer 再到 Parallel Experiment,感覺製作組誠意滿滿,一直在發想新的解謎方法,這一作也是最長最豐富的(一直以為要結束了結果還有),雖然到最後對故事的印象不深,但是關卡設計的難度以合作遊戲來說剛好、也有各種不同的樂趣,推薦。
