World Corrupted City/Town

I think that making villages or even some cities have a rare chance to become corrupted would be very cool. It is based on the old swarms and now worldevents. At a random time a village or city will get a countdown of about 10 to 15 minutes. In this time players will have the chance to run or prepare. After the countdown ends there will spawn corruption spikes or you will get a flashback from the corruption war. After that the guard golems will be disabled and loads of mobs will invade the village. All the players in the village have to work together to defend the village. So basically a worldevent in a village or city.

 

We played around with this idea but ultimately didn't do it. It would require some additional technology w/ world events to work well that we don't currently have
