Sub-ZER0's Anarchy World
Thanks to contributions from @SubZER0, we've open up a 3rd free world!
Sub-ZER0's Anarchy World will be an open world with no rules—you can really do ask you wish. Use bombs, drills, spawn enemies, and more. Hell on Earth (Terraria?).
We only ask that you be respectful to others and refrain from doing things you know will crash the server.
