In this datapack you are spawned in a world that generates COMPLETELY underground. Much like the nether there is a bedrock ceiling, thus preventing you from ever reaching the surface.

Your goal?
Survive underground!


The world will provide you all the resources you need to survive in this claustrophobic environment but can you thrive? The only biomes that generate are Dripstone, Lush caves, The deep dark and stony shores but do not be deceived, It turns out that certain structures that would otherwise not be able to generate in these conditions still manage to spawn in, providing you with a bunch of resources that you would not otherwise be able to obtain, and of course the nether and end are still accessible.


  Can you make it to the end?

  Can you sustain yourself?

  There's only one way to find out...



Good Luck Cave Dweller!


Here's a list of some fun challenges/milestone to achieve:
  • Make a chicken farm
  • Obtain Grass blocks
  • Get a sapling of every type
  • Cure and trade with villagers  
  • Get every crop type
  • Find a Trail Ruin

BV1E54y1p7WR Cascades This reminds me of a server. Are you planning to bring the Nether back to life and turn the End into floating islands? Could you make the terrain similar to the old Nether from 1.15? I prefer sparse vegetation and medium-sized caves, or maybe add rivers and grasslands with fruits that grant night vision. I just want to go back to that summer—all these great ideas kept me happy with every update.

Because of this datapack, it's always night in my world...

Does this include special cave generation like higher frequency of the underground biomes or larger caves?

Played in on my 1.21.8 world, it's quite challenging an fun! However, i tried to load it on 1.21.9 snapshots it seems the datapack no longer works,

It looks amazing. I want to play it as soon as possible. Does it only work in 1.21 or some older versions too?

I haven't tested it but the world gen tweaks are fairly simple so I imagine it will probably be fine!
