The Nether



Hell is part of the Minecraft Halloween Update. Not much is known about it; only these things are sure:


 * Used for fast travel (More about this in the section below)


 * The only way to get in or out of it is by using portals, players can't just mine straight down and hit hell.


 * Special mob types (at least 2):
 * Ghasts - hostile, flying, jellyfish-like monsters which shoot fireballs and are immune to fire.
 * Pigmen - peaceful, humanoid creatures. Currently they won't serve a purpose.


 * Special block types (at least 6):
 * Red Mossy Cobblestone - burns indefinitely, the main block forming Hell.
 * "Australium" - a golden block. Australium is not the official name, it was nicknamed so by PCGamer.
 * Unnamed - a currently unnamed grey block resembling a creeper face.

Portals and Fast Travel
The portals are made by creating a 4x5 (2x3 on inside) door frame out of obsidian and then lighting the inside of the frame on fire. When you walk through the portal for the first time, it will create a portal in its equivalent Hell area.

When re-entering the normal world, any distance covered in the hell world is multiplied by 16 times, effectively making the hell a fast travel zone that allows for greater distances to be covered in short amount of time in the normal world.
