Age of Empires II: The Conquerors Expansion is the official add-on to the known RTS game Age of Empires II: The Age of Kings. The Conquerors isn't only a just a new set of campaigns, but offers streamlined play and extra features as well. The Conquerors adds five new civilizations (Hun, Aztec, Mayan, Korean and Spanish), each with their own new units, technologies, buildings and civilization strengths. With these come 11 new units such as Aztec Jaguar Man, Mayan Plumed Archer, Spanish Conquistador and Hun Tarkan, and also 26 new technologies such as caravans, herbal medicine, the thumb ring, heresy, bloodlines and theocracy. Single-player has been improved with 4 new campaigns focused on historical figures such as Attila the Hun, El Cid and Montezuma, allowing players to ride alongside the Hun invasion of Europe, battle the Moors in Spain, preside over the siege of Tenochtitlan, or relive eight other battles that became turning points in history, such as Agincourt, Manzikert and Hastings, with such conquerors as Henry V, Yi Sun-shin and Erik the Red. In addition the game includes several new maps such as the dense rainforests of Yucatan and the frozen waters of Ghost Lake. All-new Real-World Maps allow players to re-create classic conflicts in geographic areas such as Italy and Japan. The Conquerors seems to be an excellent add-on for an already excellent game, with plenty of new additions for hard-core Age of Empires players as well as further improvements to the gameplay for newbies to the series.
