What is the Hack The Planet ATM9: Sky server?

The Hack The Planet ATM9: Sky server is a custom-optimized multiplayer skyblock experience based on the All The Mods 9: Sky modpack.

It reimagines the classic ATM9 adventure — but set in the sky! Start from a floating island, expand your base, and automate your world from nothing into a thriving high-tech empire.

This isn’t a simple skyblock — it’s massive, community-driven, and performance-tuned for long-term play.
