This item is very old and has not received maintenance, but nonetheless still appears to work.
General
This mod overhauls moon generation to make exploring them more rewarding and interesting, while keeping a vanilla feel. It adds several new biomes, expands the ore profile, and in general adds more variety and value, particularly to greater depths. In addition to new ores, it makes erchius spawns gradually denser the deeper you go.
Biomes
Blasted
This surface biome is a cratered wasteland, covered in meteor remnants. As a result, it also has a high quantity of metal ores, including some not found elsewhere.
Carbonaceous
Deposits of organic material are common on the surface here, kept warm by tar and a small amount of lava.
Junkyard
The surface here is littered with debris and waste, used as a dumping ground in some distant past.
Ice Caves
These shallow caves are mostly devoid of ores, but small pools of liquid water are common.
Shadow Caves
Just beneath the surface in some areas, a few shiny things here and there dot jet-black caverns.
Erchius Sea
At a mid-level depth, you can find massive seams of liquid erchius.
Geode
Deep underground in this region, the terrain consists of lots of obsidian and magmarock shells, some still full of lava. Valuable gems are found here.
Crystal Caves
These deep caves are rocky but abundant with glittering crystal.
Metallic Core
Some moons will have a core studded with the sunken remains of ancient meteoritic bombardment; this rare find is very rich in both metals or crystal erchius.
