Honest Hardcore is a gameplay mod that enforces real consequences in Minecraft's Hardcore mode.
It disables the "Spectate World" button after death and replaces it with a "Statistics" button. You can no longer escape death by switching to Spectator or Survival mode.
In addition, the mod tracks the world's honesty status. If you ever enable cheats or enter Creative mode — the world becomes marked as dishonest. From that moment:
All advancements are permanently blocked
A single crossed-out advancement ("Honesty") remains as a reminder of your actions
For honest players, a chain of special advancements becomes available — one for creating the world, and more for surviving without cheating.
This mod is designed for singleplayer only. No server support.
