真正的极限模式
Java mod listed for Minecraft 1.21. Downloads from the MC Java Mods app on Android.
⬇ Download on ModrinthTrue Hardcore Fix
A lightweight Fabric mod for Minecraft 1.21.11 that makes Hardcore mode truly hardcore.
Features:
- Locks the "Allow Cheats" and "Game Mode" buttons in the Open to LAN screen when playing in Hardcore mode. You cannot enable cheats or change game mode no matter what.
- Automatically encrypts your level.dat file when you save and quit. This means the world cannot be loaded if the mod is removed. Re-install the mod and the world works normally again.
- Rollback protection: if you try to replace your world with an old backup after dying, the mod will detect the rollback and permanently mark the world as cheated. The world can never be loaded again.
This mod gives you three layers of protection, making Hardcore survival truly fair and unforgiving.
No configuration required. Just install and play.
