CaveMC is a survival server that feels like vanilla but way more intense. The big twist is the entire overworld is underground so there is no surface at all. It is just caves forever with biomes resources and structures to find.
It is semi anarchy so survival is brutal and you have to be smart to last. Season 2 is out now with a fresh start and more stuff added.
A new expansion called the Wasteland Dimension is opening on November 8th. It brings new gear to fight over huge mega structures with secrets and its own currency for a player driven economy. There is also a new spawn and the dimension has a custom generated map with special features you will not see in normal Minecraft.
