The Eagle Warrior is one of the most terrifying units in the early game! Its high strength, combined with the fact it's available from the very start of the game, allows the Aztecs to mount incredibly effective early rushes, comparable only to these of the Sumerian civilization. What's more, its unique ability can singlehandedly turn the Aztecs into the fastest developing civilization in the early game! With Builders aplenty, they can quickly upgrade the tiles of their cities; what's more, thanks to the unique Aztec ability, they can use Builders to speed up district creation!
The only catch is that the Eagle Warrior's ability works only against units of civilizations and city-states, not against Barbarians. This practically forces the Aztec player to make war early on, if he or she wants to take advantage of these units. Go get that pesky neighbor!
Unfortunately, this ability is lost when the Eagle Warrior upgrades to a Swordsman.
Civilopedia entry Edit
One of the two elite class of infantry (the other being the Jaguar Warriors) in the Aztec army, the Eagle Warriors were the bravest young men of noble birth and/or those who had taken the most prisoners in battle. Like the Jaguars, the Eagles used the atlatl, bow, spear and macuahuitl (wooden swords set with obsidian shards); unlike the Jaguars, the Eagles decorated their armor with eagle feathers and wore a headdress shaped like the head of an eagle with the beak wide open. And they had a hilltop temple in Malinalco. Upon taking 20 prisoners – intact enough to serve as human sacrifice – a young warrior was eligible to become an Eagle Warrior, no doubt making his family very proud. Until the Spanish arrived with their cannons, muskets, and horses, the Eagle and Jaguar warriors were the toughest bullies on the Mesoamerican block.
