Minecraft: Ultra Hardcore is a gamemode originally created by Guude and the group Mindcrack. In UHC mode, health does not automatically regenerate, so players must eat a golden apple, golden head, or use health/regen potions. In addition, the version is on 1.9, FFA (Free-For-All), and smelting is instant but will still require smelting materials plus a furnace. Golden heads obtained from your opponents can be combined into an even more powerful head. UHC Participants:. Ant -.
