Mysterium is a cooperative deduction game that challenges players to solve a crime that was committed on the grounds of Warwick manor. One player takes on the role of a restless ghost who is tasked with revealing the guilty character to a team of psychics. The other players make up this team of psychics, receiving visions and interpreting them to the best of their abilities in order to narrow down the list of suspects. But, the time is ticking—if players take too long to discover the truth, the bridge between the mortal and supernatural worlds disappears and the tormented ghost must sadly wait another year for its soul to pass on!
Mysterium allows players from all over the world to investigate together in multiplayer mode and cooperate through an in-game chat that enables fellow players to point out visual clues on a card. Players can also share their visions with other psychics and approve or reject their choices with clairvoyance tokens. In Mysterium, up to 7 players can join together for fun and engaging games. And for those who wish to enter the manor alone, a story mode offers players the possibility to discover the culprit, the murder location, and the weapon through a several hours-long investigation filled with exciting twists and turns.
