Players are either Spanish or Aztec leaders, all of whom are (ostensibly) allied with Hernan Cortez in the subjugation of Moctezuma and Tenochtitlan. There is a limited element of cooperation between players of the same nationality but, in the end, each is competing to gain the sole upper hand in the capital city through control of resources, judicious combat, and pawn movement into key areas in Tenochtitlan. - BoardGameGeek
