Oneblock Ultimate
A modern recreation of the classic Oneblock experience — rebuilt for NeoForge 1.21.1.
Oneblock Ultimate is a polished, stable, and flexible Oneblock modpack, recreated entirely from scratch. The original from TL Mods was never republished, so this is a fresh take — redesigned for modern systems and built to run any Oneblock map you want to play.
Getting started
- Install the pack with the Modrinth app
- On first launch, a FancyMenu prompt offers recommended Oneblock maps — pick one and you're in
- Later, swap in any map you like. Classic, modded, themed, or challenge-based — it all works
The pack doesn't bundle maps on purpose: we can't redistribute other people's work without their consent, and that respect is exactly what sets us apart. Oneblock Ultimate is the only pack built around that principle — and the in-game helper makes setting up your map effortless instead of a chore.
