How to Enable Hardcore Mode in Your Minecraft Server

What is Hardcore Mode?

Hardcore mode is Minecraft's ultimate challenge where players have one life. Upon death, players are permanently banned or forced into spectator mode. The difficulty is locked to hard, making survival more challenging.

Quick Guide for New Worlds

Stop your server
Open server.properties
Change hardcore=false to hardcore=true
Save and restart your server

For Existing Worlds (NBTExplorer Required)

Changing server.properties alone isn't enough for existing worlds. You must also edit the level.dat file:

Stop your server and download the level.dat file
Open it with NBTExplorer
Find the "hardcore" tag and change its value from 0 to 1
Save and upload the modified file back to your server
Restart your server

Recommended Settings

Set difficulty=hard for the full experience
Consider natural-regeneration=false for extra challenge
Use plugins to modify the death penalty if desired
