⬇ Download on CurseForgeThe author built this one for Minecraft 1.20.1 on Forge. On other versions it may install and then do nothing.
Under the surface of the overworld, metallic structures with great treasures lie in wait to be discovered... along with the creatures they contain...
Discover buried structures with rewarding loot, but be careful... there are alien dangers within. If you find yourself infected with alien spores, get ready for a really bad stomach ache (and an alien birth). God help you if whatever pops out grows up.
This mod requires GeckoLib!
This mod is inspired by the Gigeresque mod as well as the Alien franchise as a whole. Expect more aliens, structures and blocks to come in future updates!
