UHC (abbreviation for Ultra HardCore) is a popular Minecraft survival minigame that can be played alone or with a team. This mod also includes UHCRun, a variant of UHC that tweaks the game in many ways to make it 2x faster.

UHC is one of the minigames made for the Nucleoid Project, an effort to build an open source ecosystem for server-side Minecraft minigames. You may even be interested in playing some of them over on our testing Minecraft server at nucleoid.xyz! You can also find us on our Discord if you have any troubles or queries, or would like to get involved.


UHC can be installed on a client or a server. As this is a multiplayer minigame though, it is recommended to install it on a server.

⚠ UHC needs the following mods to be installed:


To start a game of UHC, use /game open and browse the list of available game modes.
