Microsoft Games has opened the official site for Age of Empires II: The Age of Conquerors. Age of Conquerors will be an expansion for the extremely popular historically themed real-time strategy game Age of Empires II: The Age of Kings. The expansion itself is currently scheduled for release this September. The Age of Conquerors site has a great deal of information about the expansion's five new civilizations: the Huns, the Aztecs, the Mayans, the Koreans, and the Spanish. The site also has a good number of screenshots, detailed descriptions of the game's campaigns, and a movie trailer.
