The cerebral cooperative puzzle game Parallel Experiment has officially launched for iOS and Android devices. As the second installment in Eleven Puzzles' Cryptic Killer series, this sequel delivers more mind-bending challenges and unexpected revelations as you race to stop the notorious murderer.
Players reunite with the detective duo from Unboxing the Cryptic Killer, who now find themselves trapped in the killer's deadly game. The stakes have never been higher, forcing players to coordinate closely with a partner to solve increasingly complex puzzles that will test both problem-solving skills and interpersonal relationships.
Featuring nostalgic noir aesthetics and more than 80 innovative puzzles, Parallel Experiment delivers the cooperative experience fans of Keep Talking and Nobody Explodes have been craving. Available now for $6.99, players can dive into the Cryptic Killer's devious challenges first-hand.

What's hiding in the box?!
Did we mention trolling your partner is part of the fun? While serious puzzling forms the core experience, you'll delight in sabotaging your teammate - whether by tapping windows or poking your partner - adding comic relief to tense situations.
Parallel Experiment offers more than just puzzle-solving. Between investigation sessions, players can enjoy engaging minigames and question NPCs who respond uniquely to each detective. Survival demands flawless teamwork - though you might question your friendship by the end.
