CaveMC is a semi anarchy survival server with an enhanced vanilla feel and it is all underground. The overworld has no surface at all so you live in a huge cave world with biomes resources and structures. It is made with custom world generation built by real Minecraft developers.
Season 2 is live so it is a fresh start and the survival is meant to be brutal. You basically have to be smart and tough to last.
There is also a big expansion called the Wasteland Dimension. It adds exclusive gear mega structures to explore and mysteries to figure out. It also brings a unique currency so players can trade and build a new economy. There is a new spawn too and the dimension uses a custom generated map with special features.
