What it does

Players start a round from the game list in the server browser, where UHC appears as one of the available game modes. UHC is a multiplayer minigame that runs on the server, so players join it without installing anything, though the server owner must install it. Fabric API and Plasmid are required dependencies. Builds cover 1.19.3 – 1.21.4, and the latest files target 1.21.4.

Key features

  2. Game mode browser
