The Wild West

As the United States expanded its territory westward during the 19th century, vast tracts of land were coveted by entrepreneurs, pastoralists, and criminals for business prospecting, cattle ranching, and the nefarious activities that a region with a minimal presence of law enforcement agents permitted. Burgeoning towns sprung up by water supplies, trade routes, arable land, and gold deposits. In this lawless world, gangs and vigilantes ruled the roost. The exploits of groups such as the Reno and Hole in the Wall Gangs and heroes (or antiheroes) such as Wyatt Earp, Butch Cassidy, and the Sundance Kid, are immortalized in the modern genre of “Western” films, capitalizing on the allure of an open, irregular climate far from the normalcy of more “civilized” urban life. In Age of Empires III: Definitive Edition, these figures are represented by several playable assets: buildings such as Saloons and Dance Halls, and powerful outlaw units like Gunslingers, Owlhoots, Cowboys, Comancheros, Renegados, and Pistoleros.
