Minecraft wiki entry for Difficulty, associated text: In Java Edition, at the world creation screen, selecting Hardcore from among the game mode options causes the player to spawn in Hard difficulty, does not allow it to be changed, and allows the player only one life. In a single player world, a player who dies can choose to respawn in Spectator mode or return to the title screen. In multiplayer, upon death, the player's game mode is automatically set to Spectator mode.
