Oneblock Ultimate

A modern recreation of a classic Oneblock experience — rebuilt for NeoForge 1.21.1.

Oneblock Ultimate aims to deliver a polished, flexible, and stable environment for Oneblock gameplay.
Inspired by the original Oneblock Ultimate from TL Mods (which was never republished), this version is recreated entirely from scratch, redesigned for modern systems, and built to support any Oneblock map you choose to play.

Important Notice

This modpack does not include any maps.
You must supply your own Oneblock world.
To simplify setup, the pack includes a custom FancyMenu startup prompt that appears when the game launches, offering links to download recommended maps.

Why Oneblock Ultimate?

A clean, modern Oneblock base Designed specifically for Oneblock gameplay — no unnecessary extras, no forced worlds. Just a stable, optimized platform for the map you prefer.

NeoForge 1.21.1 optimized
Built on the latest NeoForge ecosystem for modern performance, compatibility, and stability.

Flexible and customizable
Since maps aren't bundled, you're free to pick any Oneblock version: classic, modded, themed, or challenge-based.

Lightweight and stable
Carefully selected mods enhance progression, QoL, performance, and long-term world stability.

Built with the last two miligrams of sanity I had

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

1. Install the pack with the Modrinth app
2. On first launch, a FancyMenu prompt offers recommended Oneblock maps — pick one and you're in
3. 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.
