About Parallel Experiment
Parallel Experiment is a two-player cooperative puzzle adventure developed and published by Eleven Puzzles. Steam release date: 5 June 2025.
Detectives Ally and Old Dog were hunting the Cryptic Killer, and now they are the subjects of his twisted experiment. Each player controls one detective and sees only their half of every room, so you have to describe symbols, read out codes and talk each other through more than 80 puzzles: redirecting water, unlocking intricate locks, cracking ciphers and even soldering electronics. The comic-book art and noir story carry the case from scene to scene, and retro co-op mini-games offer a break from the investigation. It is the second standalone chapter of the series, so no prior knowledge is needed. Each player needs their own copy (cross-platform play is supported), an internet connection and voice chat.

If splitting up and describing what only you can see is what hooked you, We Were Here Too is built entirely around that idea, with one player trapped in a frozen castle and the other holding the map. We Were Here Together turns the same radio-based teamwork into a story about two explorers who must trust each other's words. For a co-op adventure with far more action between the brainteasers, It Takes Two sends a quarrelling couple through constantly changing gameplay ideas. And Keep Talking and Nobody Explodes is the purest party version of asymmetric communication: one person defuses a bomb while the others read the manual aloud.
