About Parallel Experiment
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.
KEY FEATURES
? Two Player Co-Op
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.
? Challenging Collaborative Puzzles
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!
?️ Two Can Play That Game
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
?️ Cooperative Dialogues
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!
?️ A story told in panels
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.
✍️ Draw on… Everything!
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…
? Annoy Each Other
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.
How much does Parallel Experiment for PC cost right now?
Parallel Experiment for PC starts at €1.08 (€1.13 with fees) at Difmark, 88% under the €9.75 (no fees) of the official store — but that is a shared account, not a key of your own. If you want a key tied to your own account, the cheapest is €2.39 (no fees) at Cdkeys Com.
That €1.08 (€1.13 with fees) already includes the Gocdkeys coupon, so apply it at checkout or the store will show you a higher price.
Just 9 stores stock it, 10 offers in all, so there is little here to push the price either way.

Is it worth buying the Steam Key for Parallel Experiment now or waiting?
That €2.39 (no fees) key is at its usual price: no bargain, no spike.
- Those €2.39 (no fees) are 1% below what it usually costs, measured on the store price.
- 8 stores sell the Steam Key at the same time, and with that much competition the price moves almost daily.
- Not counting today, 36 days out of the 156 days on record were this cheap or cheaper; the lowest it has ever cost is €1.41.
Worked out from 1,202 daily records of the Steam Key for Parallel Experiment across 10 stores. See the full price history.
The price does not include each store's payment fees. The percentage is measured on the store price, without coupons, because that is how we record the history. The analysis only counts Key offers. Shared accounts, Steam Gift and physical editions stay out, because they are not the same product and their prices move differently.
Which Parallel Experiment format should you buy?
With the shared account at Difmark you log into an account that already owns the game: it is the cheapest route, but it never becomes yours and the seller keeps the credentials. If they ever lose or change them, you lose access.
The key at Cdkeys Com costs €1.31 (€1.26 with fees) more, but you redeem it on your own account and the game stays there for good. That is the difference between renting and buying.
Can you activate Parallel Experiment in US?
All 10 offers are Global, so the code redeems on any account no matter where it was created.
Why is there such an expensive Parallel Experiment offer?
One listing is worth ignoring: the Steam key that Humble Bundle has at €9.99 (no fees) is more than 8 times the cheapest offer and is not what this game costs. The number to work from is €2.39 (no fees) at Cdkeys Com.
