Underworld Mod

What is Underworld Mod



Underworld Mod is created by eAndPi that makes use of the Nether's terrain to create a massive cave-world that has overtaken the "Overworld".

Naught but stone, ice cold water, and Monsters en-masse hunting you down in this forever dark place.

Can you survive and thrive in this place where the sun has never shone?


To generate an Underworld map:

SinglePlayer: Just select "Underworld" in the available maps, just like you would select a flat map.

Multiplayer: In the server.properties file, change the line: level-type=DEFAULT to level-type=CAVES, and be sure to delete the level.dat & overworld region files.


Underworld also brings (very) few new blocks & items to help:

  • The Brazier is a decorative light-source, but requires flint-and-steel to be smacked on it to light up.
  • The Lantern is a dynamic light-source to help you as you venture around in the eternal night of Underworld.
  • Hang Vines spawn in the ceiling of this massive cave-system, and are Ore-Dictionaried to vanilla string.

Underworld is extremely young, so there will be bugs and issues. Please help by finding them all!
