NetherEx Mod 1.15.2/1.14.4/1.12.2 is a big remake of the Nether with three core ideas, Expansion, Experience, and Exploration. It has added four strange Nether biomes to the game.

What does NetherEx contain?
It is a large reworking that only focuses on the ideas above. Each new Nether biome will come with its specific goal. Everything will happen within the Nether.
In fact, every biome is unique and has a different approach.
These communities will introduce newer creatures. Blocks not existing before will be their decoration items. Not only that, you can find out numerous objects that you have never seen before.
