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.

Ampz is a mod pack built around Minecraft 1.21. It is available both on the Curseforge and on the Technic Launcher. The Ampz modpack consists of various mods that use the Electrodynamics electricity API in addition to several others compatible with it. It intends to be as similar as the original Voltz way back from 1.4.7 as possible.

Bring the world at your knees with missiles, bombs, machinery, and all of the creations you can figure with your mind!
