Two factions. One decision only you can make.

Most puzzles are finished the moment you solve them,
C-37 still has more story to tell

A puzzle experience like no other. C-37 is engineered to not only be solved but be worth solving again. Two factions want what is inside, and they want opposite things done with it. Only one of them can have your answer, and the side you pick decides how your unit ends. Change your mind, go back in, and it ends differently.

A puzzle, a story and a decision in the same object. Worth solving more than once, whether the next solve is yours or someone else's.
