Parallel Experiment is a mind-bending co-op puzzle thriller arriving on mobile later this year

Parallel Experiment: A Co-op Crime Thriller Puzzler Coming to Steam and Mobile

Eleven Puzzles' highly anticipated co-op crime thriller puzzler, Parallel Experiment, is set to launch on Steam this March. A mobile demo is also planned for iOS and Android later in 2025, with a full mobile release to follow.

The game casts players as detectives Ally and Old Dog, tasked with solving the mystery of a ruthless killer. Similar to titles like Keep Talking and Nobody Explodes, players will often be in separate locations, requiring communication and collaboration to solve over 80 unique puzzles.

What's in the box?!

Key features include an in-game notebook for tracking clues, cooperative dialogue, a stylish noir comic book aesthetic, and even interactive ways to playfully annoy your partner (knocking on windows, poking, etc.). Cross-platform play will be supported, offering a unique twist on co-op gameplay, whether playing together on separate devices or in the same room.

While the co-op puzzle genre is established, Parallel Experiment aims to leverage existing experience to deliver an optimized mobile experience.
