Unable to talk, the amnesic ghost will communicate with the mediums through visions (illustrated cards). They will have to decipher the images to help the ghost remember how he was murdered (who? where? which weapon?). The more they cooperate and guess, well, the easier it will be to the catch the right culprit. It offers cooperation and investigation with an asymmetrical gameplay. While playing the ghost or a medium, you will have fun trying to guess what other players have in their minds! So enter in this strange manor and let yourself be led by your intuition! In Mysterium, one player takes on the role of the ghost and over the course of a week, tries to lead the investigators to their culprit. Each night the team will be met with visions, but what is the ghost trying to tell you?
