A NeoForge 1.21.1 remake of the 1.12.2 Nether Overload idea for Dimension Survival. You wake in the Nether. The Overworld stays sealed until you use a Rift Key.
Requires a new world. Worldgen and the spawn camp do not retrofit existing chunks.
Download also available on GitHub Releases.
Nether Overload was created by MCJediYoda. This is a from-scratch remake, not a continuation of that CurseForge project. https://www.curseforge.com/minecraft/mc-mods/nether-overload
