Players can defend Spain as El Cid, rage across Europe as Attila the Hun, or fight to preserve an ancient way of life as Montezuma in new campaigns that extend the single-player experience. Plenty of toys are available to each civilization, including new technologies such as Chinese rocketry and British yeomen. But none of the new technologies or units unbalance the game. In fact, many of the units from AoE2 have been altered in response to gamer feedback so no one unit or civilization has an overwhelming advantage.
