At their height, the Aztec represented the most powerful civilization in Mesoamerica. The Aztec constructed great cities, most notably Tenochtitlan in the site of modern-day Mexico City. Described by some early Spanish as grander than most European cities, Tenochtitlan's advanced infastructure included temples, markets, and canals.
In Aztec society, membership in the calpulli established each individual's religious and secular schooling, as well as warfare training. The men of calpulli served together in battle and on numerous public works projects.
The in-game Aztec civilization is based around a strong infantry consisting of several units, including elite infantry troops.
