Parallel mobile game launches with 2-player puzzles
Parallel Experiment Launches on iOS and Android
- Team up with a friend to outsmart the sinister Cryptic Killer
- Collaborate or sabotage - survival depends on your choices
The brain-twisting cooperative puzzler Parallel Experiment is now available on iOS and Android. As the sequel to Eleven Puzzles' Unboxing the Cryptic Killer, this installment delivers even more shocking revelations and complex challenges in your mission to stop the notorious killer.
This time, the detectives from the first game find themselves at the Cryptic Killer's mercy. The stakes have never been higher, forcing players to partner with a friend to solve increasingly devious puzzles that'll test both your problem-solving skills and your ability to work together.
Featuring a stylish retro-noir aesthetic and over 80 brain-teasing challenges, Parallel Experiment offers the perfect co-op experience for fans of Keep Talking and Nobody Explodes. Available now for $6.99, it's time to put your teamwork to the ultimate test.

What's in the booox?! And let's be honest - sometimes the best part is messing with your partner. If things get too serious, you can always disrupt proceedings by tapping windows or playfully poking your teammate.
Beyond the main puzzle-solving, Parallel Experiment offers engaging minigames and dynamic NPC interrogations where characters react differently to each player. True cooperation isn't just recommended - it's your only chance of escaping alive (though the experience might just kill your patience first).
