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.

The two player partner system connected online made solving puzzles so much more interesting & immersive. You need your partner's help to solve puzzles as they have been smartly designed to be worked upon together by sharing information to other side of your call/mic. Puzzles aren't too difficult either. Without solving them, you can't go ahead in the mission so it really feels like you're solving a case in real time. However, this one is just a prologue that could be completed in an hour.

Really enjoyed playing with my friend. It made us think. The only reason I am giving 4 is because there is only 3 levels in the game. after that we need to purchase another game to continue with the case.

★★★

Sama Soya

It's a really nice game. I hope there's an option in the future so I can play it alone. There's not always someone to play with you.

had high hopes and a cool concept, but game play kept saying "waiting for player" after the phone locked.

Not worth it. You can't sign in as it kept giving a developer error. The screen froze and we had to restart. Since it wouldn't allow us to sign in, we had to restart the game every time. It looked like it had potential. Maybe once they fix the developer error.
