Familiarize with GregTech: Community Edition Unofficial before playing. This is not a beginner-friendly modpack!

GregTech: Supra - Transcendent offers a challenging playthrough on an Skyblock island in the middle of nowhere, with realistic chemistry and long strenuous processing lines throughout the entire modpack.

Gregtech is the spotlight of the game, progressing through various tiers of technology. From the Steam age, then Low Voltage (LV) to Overpowered Voltage (OpV). Gregtech alone is boring, so multiple additional mods have been added, such as:

Ex Nihilo Creatio adds a sieve from which you obtain resources
Thermal Expansion featuring new technology helpful throught your playthrough
Flux Networks which allows you to transfer energy for your machines wirelessly
Solar Flux Reborn allowing you to make very powerful Solar Panels for easy power generation
Simple Storage Network adds a simple Digital Storage System
Refined Storage albeit unlocked in the later stages of the game, allows very easy automation
Botania in case you want to try out some gardening with Mana Flowers
Astral Sorcery for when you want to harness some Starlight from the cosmos

No Gregtech modpack would be complete without a guide of some sorts. FTB Quests serves just for that. With a detailed and throughly-developed questbook which documents your every step. If you ever feel lost while playing, just consult the questbook.

The modpack is an Expert modpack, which means the progression is strict and the recipes are very diffcult. The final goal is to get the Creative Quantum Chest which grants infinite items. Many custom items and machines have been added to make your playthough both harder and easier. While creating the world, set the world type to Garden of Glass.

This modpack is finished until ZPM, but theoretically playable until UHV. If, while playing the game, you encounter any bugs, please do not hesitate to report them, and I will gladly fix them.
