The incredible momentum behind "Age of Empires III" continues as Microsoft Game Studios and Ensemble Studios announced their plans for delivering an expansion pack to gamers in 2006.

The new expansion pack will build off of the exciting real-time-strategy gameplay of "Age of Empires III," providing players with the ability to lead one of three proud Native American civilizations, including the Iroquois Confederation, to expand their empire and fight for control of the Americas.

The expansion pack, which is due on store shelves in the autumn of 2006, will provide new ways to play and win, introducing new gameplay elements and content including new civilizations, a new single player campaign, Home City enhancements and additional maps and units. Additional content will be added to all existing European civilizations as well.

"Age of Empires III", which launched in November 2005, is the fastest selling title in the franchise's history, placing gamers in the position of a European power struggling to explore, colonize and conquer North and South America, roughly during the time period of 1500 to 1850. The game has garnered numerous awards, including GameSpy's 2005 Top Ten PC Games of the Year and PC Gamer's Editor's Choice. It has sold more than one and a half million copies to date and is currently among the top selling games for Windows titles.
