Catacombs: Dark Passageways (2011)

Catacombs: Dark Passageways is a card-based mini-expansion for the original Catacombs game. This expansion introduces new "exploration" room cards which add exciting effects to the base game while the heroes are exploring the Catacomb. The heroes can uncover unexpected benefits to aid them in their quest; however, the Overseer controlling the monsters can also unleash new dark powers to thwart their efforts.
