This article is about the Age of Empires III unit. For other uses of the term, see Chu Ko Nu.

Archaic Chinese crossbow that fires at an extremely fast rate. Good against infantry.
—In-game description

The Chu Ko Nu is an archer in Age of Empires III: The Asian Dynasties that is unique to the Chinese and trained as a part of the Old Han Army and Standard Army. It is similar to the Crossbowman, but fires in bursts of three shots like its counterparts in previous games.

Overview[]

Chu Ko Nu is the effective option for the Chinese to counter heavy infantry and light cavalry although they are not a best option against ranged cavalry such as War Wagons, Howdahs, or Yabusame due to their shorter range and low base damage.

The Chu Ko Nu is relatively cheap and are available since Commerce Age. Due to their fast firing speed, the Chu Ko Nu's arrows deal only 5 damage, less than a Crossbowman, but fires three shots simultaneously and has bigger multipliers against heavy infantry and light cavalry. Also, they can be enhanced with the "Old Han Reforms" Home City Card, which allows them to be used in later Ages. They fall quickly to hand cavalry as they are fairly weak, with only 90 hit points.

The Repelling Volley Home City Card increase their multipliers against heavy infantry, ranged shock infantry, and light cavalry into 3.0x, although they have a negative multiplier against cavalry and shock infantry, making them particularly weak against heavy cavalry units such as Sipahi and Cuirassier.

History[]

The Chinese chu ko nu repeating crossbow was known for its simple design and incredible rate of fire. It held a magazine of 10 bolts with steel tips, which it shot in succession, and was operated by grasping the stock in the left hand and working the lever with the right. In that swift movement, a bolt would drop into place, the string would be strung, and then the bolt would be fired, with another bolt dropping in to take its place. The weapon was specifically designed to fire rapidly and be turned on groups of enemy troops at a distance of no more than 150-250 feet. It was especially effective against cavalry. Horses provided large targets for the generally inaccurate chu ko nu, and when the animal was wounded it usually lost control and sowed pandemonium in the surrounding ranks.

Stories of the chu ko nu date back to 250 BCE, when legend has it that the first Chinese emperor Qin Shi Huang used the weapon to shoot sharks for sport. Most accounts, however, have the creation of the chu ko nu occurring during the Chinese Han Dynasty, around the year 200 CE.
