New Hardcore Mode

A new level or "version" of Minecraft Hardcore where you are still able to respawn initially after dying, but a dead body will be left behind after you die. Exactly three minutes after you respawn, that body will reanimate with three times your hearts, the ability to break blocks, and will pursue you. If you are able to continuously run from it or kill it, you get to live. If it ever kills you, your game is over and you are left to spectate.
