Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

Bieluuu's Hard Dungeons

🕳️ Late-Game Dungeons – A New Challenge Awaits

This datapack introduces brand-new, challenging dungeons designed for late-game Minecraft players. These structures spawn naturally with visible surface entrances—easy to find but brutally tough to conquer.

Features:

✔️ Unique layouts – No two dungeons feel the same.
✔️ Deadly mobs & rewarding loot – Test your skills and gear.
✔️ Vanilla-friendly – No mods needed, just pure Minecraft adventure.
✔️ Multiplayer-ready – Works flawlessly on servers and singleplayer.

🎨 Coming Soon:

A custom resource pack with unique weapon textures to make your loot even more special! (Optional, but highly recommended for the full experience.)

🔹 Credits & Thanks

A massive shoutout to Timsmak, who built nearly every structure in this datapack! Without his incredible work, this project wouldn’t exist. (Sadly, he doesn’t have a Modrinth account, so I can’t credit him properly here.)
