The Incas are a South American civilization featured in the Age of Empires II: The Forgotten expansion. They are an infantry civilization, a South American civilization from the Post Classical Period (or Late Horizon), and the most expansive and extense in Precolumbine America.
Their house bonus helps them save wood and allows them to create units faster. Having villagers tougher as infantry, they can defend the base when soldiers are away.
As being from the Americas, they lack all cavalry, but they have full barracks lines and can research all available technologies at the Blacksmith. They also lack gunpowder units, but unlike Aztecs and Mayas, their Slingers fulfil that role effectively.
