Welcome to

Think you know modded Minecraft? Forget everything. GregTech: New Horizons is a hardcore journey through one of the most ambitious, complex, and rewarding modpacks ever created.

You begin with a stick and a rock and you will end up building quantum machines, space stations, and even interdimensional bases. Every step forward is earned. Every achievement, hard-won.

GT:NH isn’t for those who want instant gratification. It’s for players who love understanding systems, optimizing builds, and slowly building a technological empire. If you crave challenge, this is it.

With over 300 carefully integrated mods, dense tech trees, a logical progression system, and deeply interconnected mechanics, GT:NH offers a truly unique experience.

But you’ll never feel lost. A detailed questbook with over 3900 quests will guides you through complex systems, goals, and unlocks, making learning part of the fun.

In GT:NH, there is never just one way to progress in the game. Whether you are a fan of complex production chains and advanced optimizations, a renowned thaumaturge, an advocate of renewable production, an outstanding beekeeper, or a master of botany, GT:NH has something to offer you.

What's more, even for your play style, GT:NH offers you various ways to solve a problem, imposing only the milestones of your progress.

Be the sole master of your progress!

GT:NH isn't a bunch of JARs dumped into /mods, it's a big project with deliberate vision that doesn't limit itself to off-the-shelf solutions.

We develop and maintain:

• Dozens of forks of popular mods
• Many exclusive mods, made for GT:NH from the ground up
• Resource packs, shader packs, localizations and more!
• We are even compatible with LWJGL3 and Java 25!

As a result, GT:NH is able to run on modest computers!

The GT:NH community is made up of highly technical and passionate players: engineers, science enthusiasts, and logic lovers who thrive on complexity and optimization. While the community is generally helpful and welcoming, it expects you to make an effort and do your research before asking for help.

Most discussions, guides, and spreadsheets are in English, but we also have dedicated channels for Chinese, French, German, Polish, Portuguese, Russian and Spanish speakers. If you enjoy learning, problem-solving, and engaging with like-minded players, you’ll feel right at home.
