Age of Empires III: The Asian Dynasties is the upcoming second expansion pack to the award-winning Age of Empires III being developed by Ensemble Studios, developer of Age of Empires III; and Big Huge Games, developer of Rise of Nations. Besides the New World, players will now get to play in Asia as well. The three Asian civilizations will have 15 new wonders, which will be the equivalent of aging up for the European civilizations. The game will also have three new campaigns consisting of five scenarios each, each campaign focusing on one of the new Asian civilizations. The game will be released on October 23, 2007, around the tenth anniversary of the first installment of the Age of Empires series.
India — Has no villager cards, but gets one villager with each shipment.  All non-shipped villagers will cost wood instead of food. From the military standpoint, there will be several different types of War Elephants, including the Mahout, along with Sepoys as an infantry unit, and artillery units such as cannon mounted elephants. Their wonders will be the Agra Fort, the Taj Mahal, the Karni Mata, the Tower of Victory and the Charminar Gate. One of India's monks will ride an elephant and heal units in combat.
China — Has migration cards that allows them to spawn one villager at each town center and village (Chinese house). Only gets one monk to start with. According to some screenshots, the Chinese will be specialized in ballistic and artillery, with units including the Chu-ko-nu (also seen from Age of Empires II), Manchurian cavalry and riflemen, and a flamethrower unit. The Chinese will also have a higher population limit than all the other civilizations. It is confirmed that they will not be able to train individual units, but instead, "Banner Armies", from the War Academy, which is a combination of the Barracks, the Stable, and the Artillery Foundry. Banner Armies are a combination of two different units in one package. The "Old Han Army" is a combination of Qiang Pikemen and Chu Ko Nu archers.
Japan — Can only ship a 2 villager card in the first age, but can send it twice. They also have the Hatamoto Samurai, a very powerful samurai unit that commands other units. They also have the Daimyo unit, which is like a walking Fortress, in the fact that it can continually train troops and artillery during battle. They cannot gather food via herding or hunting, but build shrines around huntable and herdable animals to gain a food trickle, they may still fish. Their wonders are the Great Buddha, the Toshogu Shrine, the Golden Pavilion, the Torii Gates and the Shogunate, which grants the player a Daimyo. As a special advantage, most cards in the Japanese Home City may be sent twice. They have expensive but powerful military units, the backbone of their armies is the Samurai unit.
