Parallel Experiment's Steam launch delayed to June, syncing with mobile versions

Author : Zoe May 05,2025

The highly anticipated cooperative puzzler, Parallel Experiment, from Eleven Puzzles was originally slated for a Steam launch in March. However, due to unforeseen development challenges, the release has been delayed. Fans can now mark their calendars for June 5th, when the game will simultaneously launch on PC, Android, and iOS.

For those eagerly awaiting the mobile version, there's good news: the developers decided against scaling back the optional puzzles, additional mechanics, and the mobile version itself to meet the initial deadline. This decision ensures that all versions will be released at the same time, complete with crossplay functionality from the get-go.

In Parallel Experiment, players will step into the shoes of detectives Ally and Old Dog, who find themselves ensnared in a sinister experiment masterminded by the Cryptic Killer. To progress, players must work together to solve a myriad of interdependent puzzles that demand teamwork and communication.

With over 80 unique challenges, you'll be tasked with cracking codes, manipulating water flows, hacking into systems, and even rousing a drunken character. The game's noir-inspired setting and comic book art style enrich the mystery, drawing players into a thrilling race against time.

Parallel Experiment Gameplay

The investigation isn't solely about solving puzzles; between challenges, players can engage in retro-style mini-games like darts, claw machines, and match-three puzzles, all with a cooperative twist. This adds a fun diversion to the intense puzzle-solving.

Interactive dialogues enhance the mystery, with NPCs responding dynamically to both detectives. For a bit of mischief, every level offers opportunities to playfully annoy your partner, from knocking on windows to shaking their screen or even drawing something mischievous in your detective notebook.

Boasting five times the content of Eleven Puzzles' previous project, Parallel Experiment is set to elevate cooperative gameplay to new heights. The game will launch on June 5th, and you can visit the Steam page for more detailed information.
