Critter-A-Pult: Tosses a sheep at the target. when the sheep lands, sheep beging falling from the sky for a bit
Mangonel: Launches more than one rock
Wormholeapult: The Catapult's projectile sucks units towards it while flying thru the air ( small AOE )
Sprite Launcher: Launches a Fire Sprite ( use Lava Spawn model ) that, after landing, runs around randomly, spreading fire behind where it walks
Trebuchet: Large missle. after hitting, the missle remains lodged in the ground, creating an impassible area.
Airport-A-Pult: Launches a plane/bird of some sort. this flying thing will continuously drop very small missles in its flight path. after crashing, a larger AOE occurs
Flock Cannon: Launches a Wyvern Cage ( the metal one ) modeled prejectile, that, after striking, does a small amount of damage, then creates many of the same kind of sheep the players are, that run around until hit by catapults, disrupting movement
Orc Siege Launcher: Throws a grunt. upon impact, has a VERY small AOE. there is a small chance that the grunt thrown will survive the fall, get up, and start trying to butcher the players ( should not do very much damage, and is affected by catapults. health: 1 )
Smart Sieger: Launches to the position of a player, instead of a random point.
