You were caught out in the cold and found an abandoned cabin in the woods. The wind pushed the door open before you could knock. The fireplace lit itself once you were inside and the door closed behind you. In the center of the room is The Madvent Calendar: twenty-four doors, each one a gateway to a different world of horror and delight. The catch is that a door can only be opened on its corresponding day. A horror anthology advent calendar with twenty-four games that unlock one at a time.
