Age of Empires Series Wiki

The Aztec nobles rally, giving you approximately 1 Arrow Knight for every 2 minutes of game length, up to 30 minutes.
—In-game description

War Song is a Big Button technology in Age of Empires III: The WarChiefs that is unique to the Aztecs and can be researched at the Nobles' Hut. Once researched, one Arrow Knight for every two minutes the game has passed, up to 30 minutes (for a total of 15 Arrow Knights), will appear in the Home City shipment point.

Each Eagle Runner Knight costs a total of 125 resources. This technology is cost-effective after the 16th in-game minute, delivering 8 units. It arrives considerably faster than training these units (10 seconds versus 37 second training time by default).

With the Industrial Age Old Ways Home City shipment, the cost is reduced to 250 food, 200 wood.


War Song is an easy way of getting a large force of anti-building and anti-artillery troops.
