In 1521, Hernn Corts destroyed Tenochtitln: a city of 15 square kilometers that had been home to over 200,000 people. Later, Mexico City rose on these ruins. Today, there are only a few remnants of the capital city of the Mexica. In this game, the players return to the time of the Mexica. They build districts (Calpulli) surrounded by canals, build bridges connecting the districts, and build buildings in the districts.
