Candra Says: "Yes, another cooperative party game! Mysterium is a great example of a game with a narrative but no story; there's a sense of drama to everything, here, and a great mood which you can take seriously or approach in a light-hearted, silly way. A great casual mystery game which works well as a quick game while munching on snacks, or even a way to introduce people to some of the core ideas of tabletop RPGs."
In Mysterium, a reworking of the game system present in Tajemnicze Domostwo, one player takes the role of ghost while everyone else represents a medium. To solve the crime, the ghost must first recall (with the aid of the mediums) all of the suspects present on the night of the murder. A number of suspect, location and murder weapon cards are placed on the table, and the ghost randomly assigns one of each of these in secret to a medium.
Unable to talk, the amnesiac ghost communicates with the mediums through visions, which are represented in the game by illustrated cards. The mediums must decipher the images to help the ghost remember how he was murdered: Who did the crime? Where did it take place? Which weapon caused the death? The more the mediums cooperate and guess well, the easier it is to catch the right culprit.
