Minecraft UHC Servers
UHC is a game mode on Minecraft servers where you and your team are teleported randomly into the map, along with all other players playing the same map. You are then given a set time to prepare, usually that's between 10 and 25 minutes, after this time PvP is enabled and the world border of UHC map starts to slowly shrink forcing you to retreat to the middle of the map.
The aim of UHC gamemode is to be the last player standing alive. Usually there are also a few exceptions, for example you will not regenerate health when get hurt so be careful. Once you die, you're out and you're placed into spectator mode to watch the other player’s journey to victory on that UHC map.
