cRPG is a modification for Mount & Blade II: Bannerlord. It adds persistent multiplayer character stats, hundreds of unique items, an online campaign, clans, duel ladder, a co-op game mode and a few more things.
A catapult is used by the Hounds of Chulainn to siege the town of New Durquba in NA Strategus.
Strategus catapults, built using construction sites and construction material, can be used to destroy walls and allow for easier access to towns/castles.
The catapult can be moved(rolled) and aimed by adjusting the direction(left/right), power, and release point.
Any hits landed on destructible walls will show a message in pink text indicating the remaining health of the section of wall that is hit.
Catapulting can be practiced on the duel server!
Often a spotter is used to call out where the catapult shots are landing to the catapult engineer.
