Bouldershot

"Small Siege unit that can launch boulders at targets. Decent at knocking down walls and buildings but not nearly as powerful as most siege weapons."

- Tooltip

Bouldershots are giant slingshots used by the Kokiri as siege engines.

Description
Essentially a giant Slingshot on wheels, the Bouldershot was the Kokiri's primary siege weapon. These contraptions could fling giant boulders across large distances to take out walls, gates, towers, and even enemy units that happened to be in the way.

Trivia

 * The Bouldershot is primarily based on the Fairy Slingshot from The Legend of Zelda: Ocarina of Time, complete with its red tips.
