How do I install Gray Goo?

Install the matching mod loader (Forge, Fabric or NeoForge) for your Minecraft version. Download the .jar. Put it in the .minecraft/mods folder and launch that loader profile. Opens on CurseForge — not every file is mirrored on our own servers.

The listing gives Minecraft 1.20.2, 1.20.1, 1.19.4, among others. This is the version stated by the author or source site, not something we verified ourselves.

Gray Goo

Java mod listed for Minecraft 1.19–1.20. Downloads from the MC Java Mods app on Android.

by Jaggwagg · on CurseForge

A Minecraft mod which adds destructive nanotechnology! This mod adds machines, blocks, and items to DESTROY your world! Fabric only for now.

Which Minecraft do you have?

Every version of the game needs its own build. Pick yours, then download — the wrong build installs fine and then does nothing in the game. This mod is built for Fabric only.

Minecraft 1.20.2Newest
Minecraft 1.20.1
Minecraft 1.19.4
Minecraft 1.19.3
Minecraft 1.19.2

⬇ Download for 1.20.2 ⬇ Download for 1.20.1 ⬇ Download for 1.19.4 ⬇ Download for 1.19.3 ⬇ Download for 1.19.2

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.

Gray Goo Mod

Have you ever wanted to bring nanotechnology into Minecraft? What if that nanotechnology self-replicated out of control? The gray goo mod has answers to all of these questions!

Fabric only right now. NeoForge will be codeveloped alongside Fabric for the 1.21 and future versions.

Due to past events, Gray Goo will never be supported on Forge.
