GregTech-Planetfall

  # GregTech: Planetfall
  ### Every mod follows the GregTech tiers - and every planet has something you can only get there

**Minecraft 1.20.1 · Forge 47.4.10 · GregTech CEu Modern 7.5.3 · ~175 mods**

Almost every mod in this pack has been reworked with KubeJS so it **unlocks at the matching GregTech voltage tier**. AE2, Mekanism, Ad Astra, Productive Bees, Draconic Evolution, Thermal, jetpacks and more all follow your progress from Steam to ZPM and beyond. No shortcuts around GregTech, but plenty of reasons to use every mod along the way.

> ⚠️ **Early release - looking for feedback!** The pack is playable through EV/IV and still growing. Bug reports, balance opinions and ideas are very welcome (see the bottom of this page).

## ✨ Highlights

### 🔧 Everything on GregTech tiers
- **AE2** starts at LV and grows with your tiers. Wireless, MEGA cells and cross-dimension storage come later.
- **Mekanism** circuits, machines, generators and the nuclear reactor are all made in GregTech machines.
- **Ad Astra rockets** are built from GT parts: Tier 1 at HV, Tier 4 at LuV, each with its own GT rocket fuel.
- **Productive Bees** run in GT multiblocks (Apiary, Advanced Apiary, Industrial Comb Centrifuge).
- **FE generators** (Mekanism, Thermal...) are gated so they can't skip GT power progression.

### 🧪 New chemistry chains
- **Zircon → zirconium & hafnium → Zircaloy.** Moon ore, carbochlorination, solvent extraction, Kroll process. Needed for Mekanism fission fuel and control rods.
- **Lithium-ion cells.** Cathode, LiPF₆ electrolyte and solvent, all made in GT. Needed for Mekanism induction matrices.
- **Rare earth separation.** Solvent extraction replaces the quick centrifuge recipe. Your only samarium source.
- **Polyimide (Kapton).** A full organic chain for IV circuit boards.
- **Plutonium & radon** have a real EV route (seed + breeder) for the Quantum Eye.

### 🪐 Planetary Industry
Every planet has something you can **only** get there:
- **Planet air** for the Gas Collector: argon-rich Martian Air, sulfurous Venusian Air, Solar Wind (helium-3) on Mercury, krypton and xenon on Glacio.
- **Mars perchlorate** is the oxidizer for tier 3 and 4 rocket fuel.
- **Space alloys** each smelt on one world only: Desh Steel (Moon), Ostrum-Titanium Composite (Mercury), Calorite Superalloy (Venus). They're used in rockets, fusion and turbine rotors.
- **Bonuses for building off-world:** vacuum smelting on the Moon and in orbit, and orbital crystal growth.
- **Planetary Environment Simulator** runs planet recipes at home, at a cost, using samples brought from the planet.

### ⚛️ Nuclear, balanced for GregTech
- Mekanism **fission** uses GT fuel processing (UF₆, enrichment, waste → plutonium / polonium). It's strong but can melt down.
- The **Industrial Turbine** and **Fusion Reactor** are tuned to GT numbers: rewarding, but no longer pack-breaking.

### 🏭 Custom multiblocks & tools
- **Mekanized Ore Refinery** (EV/IV) does the whole Mekanism-style ore line in one multiblock.
- **GregMek ore line** in GT machines, also for Mekanism osmium and Ad Astra metals.
- **Neutron Activator**, **Neural Simulator** (lag-free mob farming), **Industrial Inscriber**, **Parallel Fusion Reactors**.
- **Bedrock Ore Miners**: every chunk has an infinite bedrock ore vein.
- **GT: Nexus** with the Nexus Structure Terminal for auto-building multiblocks (AE2-linked).

### 📖 Full quest book
Main progression chapters from **Stone Age to UV**, plus side chapters for AE2, Mekanism, Nuclear, Bees, Space, Planetary Industry, Draconic and Utilities. Start with the **"What's New"** quests.

## 💬 Feedback wanted!
This is my first public pack and I'd love to hear:
- What felt **too grindy** or **too easy**?
- Which tier or chain was **confusing**? Did the quests help?
- **Ideas** for new chains, multiblocks or planet content
- Any **crashes or broken recipes** (please include the log!)

Leave a comment on this page. Every suggestion gets read.
