Frequently asked

Does UnstableSMP - 2v1000 Fight work on Minecraft 1.21.11?

Yes. 1.21.11 is the newest Minecraft version UnstableSMP - 2v1000 Fight declares support for, and the claim comes from the author's own release metadata rather than from a compatibility list somebody maintains by hand.

Which Minecraft versions does UnstableSMP - 2v1000 Fight support?

Everything the author has declared, from 1.21 up to 1.21.11. The full list is in the table above, with the Java runtime each version needs next to it.

Do I need to install UnstableSMP - 2v1000 Fight on the client or the server?

Both. Every player needs it installed and so does the server, so anyone joining without it will be refused.

Which loader does UnstableSMP - 2v1000 Fight need?

Fabric. A build for one loader will not load on another, so this is the first thing to check before the Minecraft version.

Which Java version do I need for UnstableSMP - 2v1000 Fight?

On the newest Minecraft release it supports, Java 21 or newer. The requirement comes from the Minecraft version you run rather than from the modpack itself, so on an older supported Minecraft the answer is that version's Java, not this one.

What licence is UnstableSMP - 2v1000 Fight under?

LicenseRef-All-Rights-Reserved, as stated by the author on the platform we synced it from. Check the project's own page before redistributing or bundling it.

How do I install UnstableSMP - 2v1000 Fight?

Use a launcher that imports packs, such as Prism Launcher, the Modrinth App or the CurseForge app, and open the pack file with it. The launcher installs the right loader and mods for you; installing a pack's mods by hand is the error-prone way.

Where do I download UnstableSMP - 2v1000 Fight safely?

From the author's own page on Modrinth, which is where the data here is synced from. MCReference never mirrors, re-hosts or repackages a file: every download button points at the original source, so you get exactly what the author published.
