Let's join forces using the trebuchet to exterminate all the enemies. A trebuchet is a type of catapult that works by using the energy of a raised counterweight to throw the projectile. Initially, the sling, which has a pouch containing the projectile (in this case its a cannon ball), is placed in a trough below the axle, which supports the beam.
To activate the catapult/trebuchet tap it once to activate and the tap it again to release in the right time.
