This server is called CaveMC and it is on Season 2. It is a semi anarchy survival server where the whole overworld is underground. There is no surface at all. Everything is caves with different biomes resources and structures.
The gameplay feels way harder than normal survival. You have to be really smart to survive because it is brutal and there is not much safety. It is still kind of vanilla but it has a lot of custom world generation made by real Minecraft developers so it feels unique.
They are adding a new place called the Wasteland Dimension. It is a huge new area not just a normal biome. In the Wasteland you can get brand new powerful gear and there are massive structures to explore. These mega structures hide secrets and good loot so people will fight over them.
The Wasteland also has its own special currency so there is a new type of economy where players can trade in a different way. There is a brand new spawn made for this update so when you join you start in a place that fits the Wasteland theme.
The map in the Wasteland is custom made and looks really cool. It is also built to be challenging with special features that change how you play. Overall it feels like a dangerous underground world for players who like harsh survival and exploring new dimensions.
