Mod required!
This mod requires the Caveworld Flora Mod in order to work. Please, ensure you have it installed and on a higher position in the mods list.

The Cave Biome Mod adds a new biome: Caves! Explore and settle a new colony inside the deep and labyrinthic tunnels found underground.

Cave Biome Mod features

  • Adds a new biome with custom caveworld flora.
  • Permanent darkness so growing will be hard.
  • Plants can serve different purposes: food, wood…
  • Most events can still happen (you will get raided!).
  • Adds a new mineral: cold crystal. Can be used as a permanent torch but it drains surrounding temperature.
  • Adds underwater power conduit (so you can build a colony across the river).
