>>9Catapults are on the Free version. There is a free Sandbox server that had them. But people griefed others with them and took it out of that server. Same with Bombs/Grenades/Kegs.
Also you can change the Gravity of each portable item, so you can have flying kegs.
Imagine this idea. Sticky Kegs that stick to people even when not lit. It sticks to them and makes them fly off when it has the gravity of that keg changed.
