Mists over Carcassonne

Mists over Carcassonne is a co-operative version of the well-known tile-laying game Carcassonne. Working together, you place tiles and score points while trying to stop the spread of ghosts, contain haunted ground in cemeteries, and use haunted castles to your advantage. If too many ghosts are loose on the ground or you've collected too few points when the tiles run out, you lose the game. If you do manage to survive three days, you can adjust the difficulty level of the game to increase the challenge.

Also usable as an expansion to the base game.
