Nether Expansion
by BrayDaGamer1
Nether Expansion, a NeoForge mod, adds several new biomes, dimensions, mobs, blocks and ores to the Nether, including variants that mix in overworld or End terrain.
What it does
The mod expands the Nether dimension with nine new biomes, among them Wet Forest, a water-filled biome, and Acidic Nether, a toxic Delta-style biome that adds two more biomes called Acidic Plains. Several Nether variants come with it: Overnether, a corrupted version with overworld terrain and no Nether roof, Dark Nether, a darker take on the alpha look, Floating Nether with floating islands, and Tropical Nether, which is lush and bears little resemblance to the vanilla dimension. Amplified Nether doubles the original height.
Four new ores are included: Aventurine, Infernal, Acidic and Sapphire. The mod also adds one new structure, a Nether Tower, and the author plans further additions. It is built with MCreator and is published for NeoForge only. Client and server both need it, so the server and every player must install it. The code is released under the MIT License, but the project is not open source.
