Apocalypse World

I'm thinking of an apocalypse world where, after a player has completed every dimension and achieved a lot of things in their world in Minecraft, they should be able to go to an apocalypse world where they can be judged by a boss. Depending on whether they lose, they should get thrown into lava. If they win they could decide if they want to stay in the apocalypse world or go back to the overworld.
