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.

Very great game. 8.5 / 10 The fact that you can't see what the other person sees and you actually have to communicate to figure it out is amazing. Lots of eureka moments come about when you're fiddling around for 30 minutes only for your partner or yourself to say you see something you left out in the initial room explanation. Every room seems impossible until you start connecting the pieces. Investigation mode adds that layer of replayability for easy achievement grabs. The tokens for the bar for extra puzzles is also a plus.

Loved "Unsolved Case" and "Unboxing", but this one took the concept to the next level. Massive variety of puzzles, and so many of them that the game was thoroughly juicy. Great story, too.

It is one of the better escape room games my daughter and I have played. If you like this type of game, its worth a play. Still doesn't come close to a live escape room game.
