This is a mod that adds a special dimension, in that dimension special zombies and buildings spawn, there is bearly any grass, so you will have to find abonded stores and buildings and houses to find food and weapons, no animals without the grass blocks, and if there are some, they won't spread with the coarse dirt, so good luck in surviving friend.
3 tipes of zombies added so far; The runner, the tank, and the regular zombie., They will spawn even in daytime and in the night other things will spawn...
Trees are harder to come by, and they no more leaves for sapplings.
To make the portal build like a neather portal out of dirt, and light it with the tool called Wastelands Igniter Tool or something like that (Looks like a bottle) in the tools section.
Added a new sub-biom, more structures and 1 mob you do not need to worry about.
