Darkpass is a collaborative campaign-based tabletop dungeon crawler that takes place in the dark and dismal 1854 Paris sewer system. The butcher, blacksmith, alchemist, and host of other characters combat a stream of ravenous beasts as they make their way through the grime and filth, deducing the best way to survive and forge ahead on their journey. Players must work their way through each chamber by defeating beasts, collecting items and performing tasks. Characters and beasts take turns based on a determined initiative per chamber. Characters and beasts move and take an action on each turn, through the use of action cards, which include attacks, resting, dashing and exploring. Items can be collected with the explore action and used to manage obstacles and help defeat beasts. Throughout the campaign, characters become stronger and more skilled as they progress through deeper, darker and more difficult chambers. -description from publisher
