Parallel Experiment, the cooperative puzzler experience from Eleven Puzzles, was all set to launch on Steam in March, but some unexpected challenges seem to have slowed down the development. Now, you’ll take on the Cryptic Killer in June, when the game releases on both PC and mobile.
If you were waiting for Parallel Experiment on Android and iOS, things could’ve been worse as the developers originally considered scaling back optional puzzles, additional mechanics, and even the mobile version to meet the original deadline. Now, all versions will release simultaneously, which is great given that crossplay will be available right off the bat.
In Parallel Experiment, you and your partner take on the roles of detectives Ally and Old Dog, trapped in a twisted experiment orchestrated by the Cryptic Killer. The only way forward is to solve a series of interdependent puzzles, each requiring teamwork and communication.
With over 80 challenges, you’ll be deciphering ciphers, redirecting water flows, hacking computers, and even waking up a drunk. The noir-inspired setting and comic book art style bring this mystery to life, immersing you in a tense race against time.

The investigation isn’t all high-stakes problem-solving, though. Between puzzles, you can challenge your partner to retro-style mini-games like darts, claw machines, and match-three puzzles, each with a cooperative twist.

Interactive dialogues deepen the mystery, with NPCs responding dynamically to both detectives. And if you feel like causing a little trouble, every level includes ways to annoy your partner, whether it’s knocking on windows, shaking their screen, or just doodling something questionable in your detective notebook.
With five times the content of their previous project, Parallel Experiment will push your cooperative gameplay experiences to higher levels. It will now launch on June 5th. You can visit the Steam page for more information.
