I saw some people wanted Community events were everyone needs to be involed so here some of mine feel free to add your own.
Attack of Ol West
A gang of bandits attack Ol West and everyone needs to work as fast as possiable to kill all the bandits. They would be npcs some on horses some not and they would be spread out somewhere(for example start). The bandits would have special names and a gang tag(the name of there bandit gang). They should not heal but have a pretty high amount of hp. Once all the bandits are killed a Bandit leader spawns and has a ton of hp(should of a big hitbox so everyone can hit him) but once he dies a stand appears with a reward on it for example a toy or hat etc.
Rock Slides(could work with trees fallening after a storm to)
A tons of rocks fall off the cliff and have hidden something mine them out to see what it is. Somewhere near a cliff there should be a big pile of rocks from the rock slide. These rocks should have a huge amount of hp so it take a while for every player to mine. This rock should be big enough to allow a lot of people mine it. After everyone mines the rock a stand appears with the reward(hat,toy,weapon,etc.)
Sheriff Hunt
The sheriff is trying to find evidence to solve the crime help him out.
The sheriff gives everyone a hint on how to find an item off his list(he would have a list everyone could see and it would say if the item was found or not). But everyone has a hint for a different item so you need to work together and tell everyone your hints to succesfuly find all the items. Once the sheriff recives all the items a reward will spawn(hat,toy,mele,etc.)
Hope you guys liked my ideas please tell me anything you think should be different and feel free to post any of your ideas here.
