A brushbased medieval Trebuchet I made for one of my maps. It's not an actual working sling, just static. I also know it's missing a sling, but that would be harder to model with brushes and since it's static it doesn't really need that.
At the moment I don't even know how to make this in to a working catapult, perhaps if I find out I'll update this in to a fully working Trebuchet.
Credit me when using this in a map.
