Sunnyvale's Secret Society: Mystery Hunt

For centuries, this secret society has bended the fate of your city to their will. They control everything and you were never meant to find out. Presidents, CEOs, doctors, barbers — everyone is in the palm of their hand.

Your mission is to help a retired detective who's the only one who ever came close to exposing them. A whisper from the dark has tipped you off with a mysterious clue to start your investigation. You can bring your friends —or go alone. But remember this: once you start digging - there's no way back.

Will you expose the truth? Or will you become another name on their list?

This is a role-playing outdoor exploration game that combines the challenges of an escape room, the excitement of a scavenger hunt, and the suspense of a detective investigation! You will play by yourself, following instructions on your phone and searching through 12 iconic spots in your city to find hidden clues, decipher encripted messages and piece together the conspiracy.

This isn't your typical scavenger hunt - it's half detective story, half puzzle adventure, and 100% fun. Bring your lover, your friends and even your entire family see if you can work together and solve the mystery - it's fun for everybody!
