The Heavy Catapult is an uncommon unit, and only these civilizations can train them:
- Alchemy increases attack by one point.
- Ballistics increases the accuracy.
- Engineering increases the range by 2 points.
- If played as the Hittites, the hit points increases from 150 to 300 hit points.
- If played as the Sumerians, the rate of fire doubles (same rate of fire as a Ballista).
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.
