Bloodborne: The Card Game is based on the Chalice Dungeons in the video game Bloodborne — the ever-changing labyrinths and tombs carved out by the Great Ones beneath the fallen city of Yharnam, where horrifying creatures reside. Players compete to kill monsters and take their blood. In general, Bloodborne is a game about risk management with a bit of group think, inventory management/upgrades, and tactical play.
