Age of Empires Online: Celts

Take charge with the Celtic infantry! The northern tribes are on the attack with all-new quests in the snowy regions of Celtica and beyond. Spirited Celtic warriors paint themselves with powers before battle and arm themselves with metalworking and crafting skills. Charge into battle with the fleet-footed Woad Raiders and the high-health Champions in more than 60 unique quests, including multi-stage missions. Then revitalize your siegeless warriors using healing units: the fierce-fighting Druids and the buff-casting Augurs.
