Dark Age of Camelot: Catacombs gives you the opportunity to explore underground cities--with attached adventuring areas--based on the backstory of one underground player race per realm. Since many of these new adventures are instanced, you can explore the underground world of Catacombs on your own schedule. This expansion upgrades player character art throughout Dark Age of Camelot, adds fresh content and challenges to the game, and introduces new player classes.
