One Deck Dungeon lets you jump right in to bashing down doors, rolling dice, and squashing baddies with style. By utilizing cards in four different ways (as an encounter, XP, a skill/potion, or a stat-boosting item), all the experience of dungeon delving has been fit into a compact package. You can choose to venture in alone, or bring along a friend. One Deck Dungeon is a 1-2 player cooperative game. With two sets, you can play with 4 players. Once you know your way around the dungeon, a game takes 30-45 minutes.
