About this Modpack

The most recent version might not be what you want. Go to versions to find what you are looking for.

Adds many mods that are similar to the ones used on the Unstable SMP (and some that just make sense to have)

Most important mods:

Unstable Generation (Only in versions 2.0+ of the modpack)

This mod adds the amplified, the great sea, the farlands (Wemmbu and Spoke versions), the mist, and the underworld. This mod is insanely well made and accurate and it deserves way more attention!

Orbital+ (Only in versions 2.0+ of the modpack)

Adds the most accurate version of the Unstable SMP's orbital strike cannons that I have seen. This also has a few more features, such as changing fishing rod mechanics so that the bobber is tied to the rod instead of the player, allowing multiple fishing rods to be used to activate different things, playing the wither spawn sound when players die, and setting a distance from deaths in which death messages will be shown.

Yes, but check compatibility: only use mods for the same loader (fabric) and same Minecraft version (1.21.11). Common issues: ID conflicts with recipe mods and incompatible coremod versions. The Mado dashboard mod browser only shows compatible mods and warns about known conflicts.
