Catapults are inanimate units operated by builders, which launch large boulders at enemies to do area-of-effect damage. Catapults are strong against tightly-packed hordes of greedlings. They are also able to kill floaters in one hit as well as deal heavy damage to breeders. However, it suffers from a lack of accuracy much like archers. Catapults can also hit and damage walls if their shots manage to miss their mark badly enough.

Two Crowns Kingdom: Two Crowns – The catapults have an extended range of fire and can shoot fire barrels to burn the greeds.


At least one builder is required to craft, move and operate a catapult, but two builders speeds up operation. Builders are necessary for the catapult to reload, but the catapult launches boulders by itself. E.g.: a loaded but unmanned catapult left in the wilderness will launch one boulder at the Greed without the help of any NPCs.

Builders can only ever move a catapult in the forward direction. If the outer wall is destroyed, they cannot pull the catapult back. Once a catapult is put behind an outer wall, it remains there until a new outer wall is built.

A catapult left outside the outer wall can become a liability as it forces builders to go past the wall to reload the catapult, even when monsters are still attacking.

Siege WorkshopEdit


A siege workshop in Kingdom: New Lands.

The Siege Workshop is where catapults are built. The Kingdom has access to catapults after the Town Center is upgraded to a Town Hall in Classic and in New Lands, and to Stone Fortifications in Two Crowns.

Classic Kingdom: Classic and New Lands Kingdom: New Lands – The Siege Workshop appears on the left side of the town center. The building consists of a left half and a right half, and giving 6 coins to either side orders a catapult to be built for that respective side.

Two Crowns Kingdom: Two Crowns – There is one workshop to the left and one to the right, and they only appear if the walls have expanded enough to protect their respective sector. There are also explosive barrels avaliable for purchase for 5 coins, after upgrading the town center to a castle keep. These barrels will be rolled over to the catapult and fired into the first wave of Greed causing the ground to catch fire and do rapid damage over time to any Greed that touch it.

Remaining bouldersEdit

Most of the boulders thrown by a catapult will get destroyed upon contact with the ground, but some will remain that breeders can then pick them up and throw back at the walls and subjects.

Even with this downside, catapults (and ballistas) still remain the strongest weapons against breeders, as boulders (and ballista shots) do massive damage. They do not die in one shot, but they can be taken down quickly by the combined efforts of both artillery and archers.

Exploit: Save-quit-reloading the game makes the remaining boulders disapear.


Date Game Update Change(s)
8 Nov, 2015 Classic 1.0.3 A catapult was once able to knock coins out from the player if the Monarch stood near the catapult when it is firing. If players had no coins, it would have knocked off the crown and if the Monarch was facing the wrong direction, the crown might have landed outside the wall next to one of the attacking monsters. This was the only friendly fire mechanic in the game, but after this patch, catapults can no longer hit the Monarch.


  • Activating the Statue of Archery does not increase the accuracy of the catapults.
  • Bug (Two Crowns): Standing outside of the wall that the catapult is at and if it is out of the monarch's sight it will quickly launch 3 boulders with no reload.
  • Bug (In Two Crowns)The Catapult shop can take up the place for other items such as pikemen and the forge this bug is only found on the 4th island from what is known.
