Is there a single-player mode?
No. Unsolved Case, Unboxing the Cryptic Killer and Parallel Experiment are designed as co-op experiences, so it is not possible to play them in single-player mode. Playing with friends, family or colleagues allows for diverse problem-solving puzzles, and pushes our players to communicate well together and think outside the box.
We believe that the co-op experience is a trade-off worth making for an even more enjoyable and challenging puzzle experience!
