The Catapult is an Early Middle Ages artillery unit. It is the last unit to be unlocked in this age.  

Compared to the Ballista, it gains +2 attack, giving it good attack values for an artillery unit. It doesn't gain any defense other than a slightly higher defense against heavy units, making it the weakest unit on a EMA battlefield. 

It is most useful attacking Heavy Infantry. They are effectively used when put on hills and attacking Armored Infantry or other Heavy units, where they can cause serious damage over time.  

The Catapult is followed by the Trebuchet of the High Middle Ages


The catapult gains attack on hills, making it much more useful. They are especially vulnerable compared to an average artillery unit of another age. In the EMA mounted archers come into play, which are functionally Iron Age archers on horses. These mounted archers can generally reach Catapults on the first turn, effectively giving them a bonus against them. With one hit, Catapults will be reduced to almost zero health, and as a result will have very reduced attack capabilities.

They are also less effective against mounted archers themselves, as the later gains 4 extra defense compared to Iron Age archers. The best way to use Catapults is against Heavy Infantry. Since heavy units are slow, a fast unit can lead the heavy units on a chase while having the catapult hitting them every turn. This theoretically can allow a fast unit and one catapult to win a battle vs up to three full health heavy units.

Catapults are ineffective against the Mercenary, usually doing around one hitpoint if they are in cover. Make sure to have heavy units holding off any fast or light units before they reach the Catapults.


Confirmed on PC: In battle sometimes the Catapult will quickly revert to facing a different direction than the way it was facing. For example, a catapult facing the enemy would flash to facing the other direction before reverting back to its original state. Does not have an effect on gameplay.
