Northstar Structures
A small addon for the Northstar mod that adds natural formations and dungeons to the planet's surface. This mod is still in early development — content is limited for now, but more structures are on the way!
It is not compatible with Northstar 0.6.0 yet.
Always back up your world before installing this mod. This mod generates new structures in your world. Installing it on an existing save without a backup may cause unexpected changes to already-explored chunks.
Features
New craters and dungeons generated naturally across the Northstar planet Multiple crater variants: Huge, Old Huge, and the massive Aitken crater More structures planned for future updates
