All The Mods 9 TTS: Skyblock Just Got More Sky

If you've ever looked at a regular Minecraft world and thought, "You know what? That's way too much land," you're probably a skyblock player. The challenge of starting from a single island of dirt and turning it into a factory of automation is a genre all its own. And now, with the All The Mods 9 TTS (Skyblock) pack, that experience is available for Minecraft 1.20.1.

This isn't just another skyblock pack. ATM9 TTS takes the well-known All The Mods 9 collection and drops it onto a single piece of floating dirt. It's for players who want the complexity of a massive modpack without the distraction of an entire overworld.

What It Does

All The Mods 9 TTS is a curated modpack for Minecraft 1.20.1, built on the popular All The Mods 9 framework. The core concept is simple: you start on a tiny island in the void with a few basic resources. Your goal? Use modded mechanics to expand your island, automate resource generation, and eventually build something ridiculous.

Key mods like Mekanism, Thermal Series, Create, and Applied Energistics 2 are all present. But the skyblock twist means you'll rely heavily on resource generation mods like Ex Nihilo and Sky Resources to get raw materials from nothing. It's automation from day one, or you're stuck.

Why It's Cool

This pack hits a sweet spot between "vanilla skyblock" and "full kitchen sink." Here's what makes it stand out:

  • True Progression Without Tedium: You don't have to spend hours manually sifting gravel. The early game is streamlined so you can quickly set up basic automation. The pack includes custom quests that guide you from a wood hammer to a nuclear reactor.
  • Performance Matters: Since the world is mostly void, and the pack is optimized for 1.20.1, performance is surprisingly good compared to other large skyblock packs. Fewer chunks loaded, less lag.
  • All The QoL: The pack includes JEI, Jade, and a host of optimization mods. You don't fight the UI. You fight the logistics.
  • Create Focused Questline: If you love making mechanical contraptions, there's a dedicated quest branch for Create. It's not just an afterthought; it's a core gameplay loop.

How to Try It

You can grab the pack directly from the official GitHub repo:

AllTheMods/All-the-mods-9-Sky

Installation steps:

  1. Download the pack from the GitHub releases page or use a launcher like Prism Launcher or CurseForge (if it's listed there).
  2. Import the .zip or .mrpack file into your launcher.
  3. Allocate enough RAM (at least 4GB, 6GB is safer).
  4. Launch and create a new world. The pack will generate a standard skyblock island.
  5. Follow the quest book (press Q by default) for the intended progression path.

If you're on a server, the repo includes a serverpack folder with the needed files for a dedicated server.

Final Thoughts

Developer-wise, there's not much to "build" here unless you're contributing to the pack. But as a player, this is a great example of how to take a massive modpack and turn it into a focused, playable experience. It's not for beginners — you'll want to know your way around Mekanism or Thermal to get the most out of it. But if you love logistics and hate walking, give it a shot.
