About Mysterium
Mysterium is a cooperative deduction game set in the 1920s. A ghost guides a group of psychics as they try to identify a murderer, the murder weapon and the location, using only visual clues. You can play as the ghost, giving clues, or as a psychic, interpreting the abstract Vision Cards.
Game modes
The game includes Pass & Play, solo play with AI partners and a story mode that reveals the background of each psychic. A variant lets you play with or without clairvoyancy.
Multiplayer
Online multiplayer supports up to seven players. The game also includes worldwide leaderboards.
Additional content
The digital adaptation follows the original board game and includes additional cases and dream cards from expansions, available in the in-game shop.
