The * indicates that the civilization can fully upgrade their Heavy Catapults, i.e. gets Alchemy, Engineering, and Ballistics.
The ^ indicates that the civilization has at least one civilization bonus that benefits the combat strength of their Heavy Catapults.


Requiring research of Siegecraft from the Market, it is the upgrade of the Catapult, with twice the amount of hit points and larger Area of Effect damage. This makes Heavy Catapults a popular Iron Age unit for bombarding enemy troops and enemy buildings. It is also the only land unit that can knock trees down with its attack damage.

Like all stone throwing siege weapons, Heavy Catapults deal 28 bonus damage against buildings (to a total of 40 damage, since buildings in Age of Empires have 80% resistance to all attacks) but only 10 bonus damage against towers (to a total of 22 damage). Only a certain number of civilizations have the ability to research and train this unit.

The heavy catapult was a powerful siege weapon, representing the greatest advance in siege weaponry during ancient times. It was employed against fortifications and on the battlefield. It broke down fortification walls, allowing attackers to break in. On the battlefield, smaller missiles could be fired in a shower against dense formations of soldiers to cause casualties and disrupt morale at long range. Enemy armies that could be softened and shaken before the hand-to-hand clash of infantry were at a decided disadvantage.
