A temple in honor of the gods has just been erected in the heart of the Aztec city. The walls inside this place of worship are to be decorated with paintings of feathered snakes to pay tribute to the gods. An election will be held to determine who is the empire's most celebrated CA^3 alt painter so that they may have the honor of decorating the temple walls.

During the game, players must complete objectives by creating a CA^3 atl painting in order to accumulate more prestige points than their opponents. Each player creates their own unique CA^3 atl by laying down Body, Head and Tail cards.
