THE STORY SO FAR
Years ago, the twisted Cryptic Killer was put away behind bars at the infamous Anagram Asylum. But today, he's back, and he's taunting the detectives. Did they catch the wrong guy, or are they looking at a copycat killer?

A new lead arrives in the form of a mysterious locked box, delivered directly to their addresses. Detectives Ally and Old Dog are once again sent on a chase that'll challenge them unlike any case before. Explore new locations, crack codes, and unravel the mystery. In this prequel, you're invited to step into the detectives' shoes and return to where it all began.

THE ONLY WAY TO ESCAPE IS TO WORK TOGETHER
Two minds are better than one, and the only way you'll be able to crack the Cryptic Killer's codes is by working together. Through separate screens, you and your friend will each be given half of a puzzle at each location. Communicate, collaborate, and work together to push your puzzle-solving skills to the limit.

Awesome. Perfect for a pair of friends. It was fun, but I feel we needed make of a challenge since apparently me and my friend are geniuses. Nevertheless, It's awesome and maybe would buy the full game.

★☆☆☆☆ Manan · Mar 14, 2026
Very bad game. Only for low iq people. Makes no sense. Just guess work and you solve the game. Won't recommend anyone to play this time-wasting game.
★★☆☆☆ Levi Morris · Aug 7, 2025
Had high hopes and a cool concept, but game play kept saying "waiting for player" after the phone locked.
