Mists Over Carcassonne is the first cooperative version of Carcasonne (see "'Carcassonne 20th'") ever released. Players will make their way through six levels of challenges by adding new tiles each turn to the board and placing meeples to score points. Throughout the game, ghosts appear on the board and players will be required to pacify them. Players must reach various goal times with a specific number of points scored. If the ghosts overwhelm the board and players can draw tiles anymore before the goals are completed, the players lose the game.

Mists Over Carcassonne comes with 45 meeples and 60 tiles. This game is for one to five players, ages 8 and up, and plays in 35 minutes.
