How to Play Hardcore Mode in Minecraft

Guide Java Bedrock

Quick answer: Create a new world and set Game Mode to Hardcore (Java: the creation screen; Bedrock: the world settings since 1.21). Difficulty locks to Hard and death is permanent - you can only spectate the world afterwards.

What you need

A new world - Hardcore is chosen at creation
Java: creation screen; Bedrock: world settings (1.21+)
Nerves: death deletes your access to the world

Step by step

Java: Create New World > Game Mode: Hardcore. The difficulty locks to Hard and cannot be changed.
Bedrock: world settings > toggle Hardcore on (added in 1.21) - same one-life rules.
Die once and the world offers Spectator mode only: fly around your builds forever, but never play in that world again.
Cheats and bonus chests are off by default in Hardcore; the Open to LAN cheat trick still works on Java if you enable it.
Survival priorities: a bed before night one, a shield before caves, totems of undying before anything risky, and never dig straight down.
Totems of undying from evokers (woodland mansions and raids) are the only in-game second chance.
Back up the world folder if you want a personal 'checkpoint' - it is your world, nobody judges.

Java vs Bedrock

Both editions have Hardcore today. Java Hardcore worlds can be reopened in Spectator only; Bedrock shows the same one-life behavior.

Versions: Hardcore has been in Java since 2011 and arrived on Bedrock in 1.21 (2024). Rules are identical on both editions now.

Frequently asked questions

Can I revive a Hardcore world?

Not officially - death is permanent. On Java, editing the world's level.dat with external tools can un-hardcore it, but that is your call.

Does Hardcore cost anything?

No - it is a built-in game mode on both editions, completely free.
