Geo Expansion
by MtCrafter1
Geo Expansion, a geology world-generation mod for NeoForge, adds over 50 stone types and more than 1000 variants spread through new biomes.
What it does
Geo Expansion is a geology mod and biome mod. Its generated stone layers and biomes are arranged so that different rocks appear in different parts of the world, and new crafting recipes use the stone it adds. The mod is based on the Bettergeo and UnEarthed mods, which were themselves based on Terrafirmacraft, and it takes some inspiration from the Vintage Story game.
The mod suits survival worlds where players want to explore a more varied underground and surface. Geo Expansion runs on the server only, so players join without installing anything, and it is released under All rights reserved as a closed-source project.
