A catapult's primary use is the destruction of walls and gates. You can hit another person with it, but it's very difficult.
To use a catapult, you must first load it with ammunition. Almost everything can be catapulted, but [[rock shards]] and [[stone brick]]s ores do the most damage. [[Quality]] and [[damage]] of the ammunition will affect the amount of damage done to your target. To load a catapult, activate an item in your inventory, right-click the catapult, and select Machine -> Load.
After you load the catapult, it must be winched. With every winch the catapult shoots 1 tile further. The minimum distance a catapult can shoot is 10 tiles, the maximum distance is 50 tiles. To winch a catapult, right-click the catapult after it has been loaded, and select winch.
After it has been winched at least 10 laps, you can fire the catapult. Right-click the catapult, select Machine and then select 'Fire'. If it was properly aimed and winched, you will either get a message in event window that you just missed the target, or that you've hit it. If it ''only'' says that you've hit nothing, your aim is off.
<s>It Catapults' trajectory is very important affected by elevation. Firing uphill requires more winching to remember that a catapult will only hit the fences on the north or west sides of a tile. Don't target the tile where the fences is on the south side, target the tile where the fence is on the north side. Even with very low skill you will hit most of the time or get a message saying you just missed the fence.</s>'''As of update 27/11/12 catapults now hit <u>all</u> tile borders!''' As of 27/03/13 catapults now shoot further if target is down slope and shorter if target is up a slope. Down slope the minimum winch is still 10 but target is hit 2 tiles further away (slope 20). Up slope you need to winch extra 2 times (slope 20) since minimum is still 10 tiles distancewhereas firing downhill requires less winching.

| [[Stone Brick]] || Less damage then rock shards, however, are also more accurate.

| [[DirtOre]] || Deals little to no dmgFrequently used during raids, collects in piles on ground. Possible use is using as it can't be used by the enemy to adjust aim or warning shotsrepair walls and it's near worthless after shot.

== Additional notes==
* A catapult will hit every wall of a tile with a house on it, <s>but will only hit the west and north walls of a tile with fences on it. Because of this it may be a better idea to use dual layers of fences, rather than a one tile wide house, to defend against them.</s> '''As of update 27/11/12 catapults now hit <u>all</u> tile borders!'''* Any item launched with the catapult will be either heavily damaged or destroyed. Any item that's is not destroyed will be at the target tile you've launched it at. * Catapults can fire over buildings and walls.
* Catapults cannot hit [[guard tower]]s.
* You can do a maximum of 20 damage to your target in one successful hit.
* Outside deeds (including perimeters) can destroy any walls (including hedges) but not buildings (regardless if owned or not);
* On deeds, can destroy anything (including owned houses) if given destroy building permission. Applies to ally and non-citizens as well.
== Multi-story Assault ==
Testing in progress; but it would appear that firing a catapult at a multi-story building will randomly damage at least one wall, window, floor, opening etc. Not yet tested on fences which have been built on buildings. ALL planned walls are damaged by the impact, however floors appear untouched - this could also apply to openings.
== Tips ==
* When attacking with a catapult during a raid, a good strategy is to use ore as ammunition. Ore does the same damage as equivalent quality rock, but unlike rock cannot be used by the defenders to repair or rebuild their walls.
* <s>Weight does not have a negligible effect on damage caused. A 20kg rock shard will do the same amount of damage as an 80kg shard.</s> There is a noticable difference. Using Combine ammunition into 80kg shot vs 20kg shot yields better chances at obtaining maximum shards in order to maximize damage per hit (20dmg).
