I got this idea after i began building vaults under earth. if you could make a plugin which rewrote all Blocks at top to be remade as sand or sandstone to make a Wasteland Look-a-like world. also if ppl then get slowly hurt when they are up on the surface in that way ppl is forced to live in the Vaults. ... Yes yes i know i just could go play some Fallout. But hey that ain't Multiplayer. Thank you beforehand.
