Catacombs is an expansion pack for Dark Age of Camelot in which players are given the opportunity to explore underground cities – with attached adventuring areas – based on the backstory of one underground player race per Realm. Many of these new adventures will be instanced, giving the player the chance to explore the underground world of Catacombs on their own schedule. The expansion features a major art upgrade to player character models that provides more detailed facial features, hairstyles, skin tones as well as enhanced armor and clothing options. The expansion also introduces one new player class per Realm.
