Hardcore Mode

Hardcore Mode is the highest difficulty level a player can choose in Minecraft.

Features
“Hardcore” only differs from “Hard” difficulty in that it cannot be changed to another difficulty while playing in the world. There is no bonus chest, and cheats are not allowed. When a player dies, the "game over" screen offers a button to delete the world, instead of the respawn and title menu buttons which appear in Survival mode. However, since update 1.9, another button is available, allowing a player to enter Spectator Mode when they die, so they can explore the world one last time. Technically, the saved world file still exists until the "Delete World" button is pressed, allowing a player to switch between apps and save the world with third-party tools. Closing the client and loading the world again only reloads the game at the "game over" screen.

Hardcore is also available in Multiplayer, but if a player dies, he/she cannot connect to the server again. Instead, a player will see a message stating: "You're banned from this server".
