Ultra Hardcore Gamemode

by ferdinandkeller · on Modrinth

Which Minecraft do you have?

Every version of the game needs its own build. Pick yours, then download — the wrong build installs fine and then does nothing in the game. This mod is built for Fabric only.

Minecraft 1.21.6–1.21.8Newest
Minecraft 1.20.5–1.21.5
Minecraft 1.20.2–1.20.4
Minecraft 1.20–1.20.1

⬇ Download for 1.21.6–1.21.8 ⬇ Download for 1.20.5–1.21.5 ⬇ Download for 1.20.2–1.20.4 ⬇ Download for 1.20–1.20.1

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

Ever wished the game had a 'Ultra Hardcore' gamemode button ?

Well now it does.

What the new UI looks like: Minecraft Game Mode selector.

FAQ

Can I remove the mod after the world is generated?

Yes you can, adding/removing the mod has absolutely no effect on existing worlds. The mod works by automatically setting the naturalRegeneration gamerule to false. No need to feedle with settings. It's just a QoL mod.

The button doesn't translate to my locale

Currently only a few languages are supported. If you want to add your language to the mix, you can either ping me to make it available to everyone, or just make a resource pack with a selectWorld.gameMode.ultra_hardcore language key.
