About this project
What does Extreme Monsters (EM) add?
Official Downloads The only two platforms where I officially publish this mod are CurseForge and Modrinth. Downloads from other websites don't really support me, so please download the mod from one of the official pages if possible. :') Any listings on websites other than CurseForge and Modrinth are not uploaded or managed by me.
⚠️ WARNING ⚠️
Do NOT install this mod carelessly! If you haven’t made a backup, a Flying Tracker may hunt you down and ruin your precious world. It’s strongly recommended to either:
-Start in a new world, or
-If you want to keep play in your current world, disable Flying Tracker spawns in the config first.
This mod no longer supports version 1.20.1.
Previous 1.20.1 builds made before the migration no longer include the latest features.
This mod places emphasis not only on combat but also on technology, so be sure to keep that in mind as you play.
E xtreme Monsters takes Minecraft survival to the next level with a full progression system built around powerful new materials, deadly Hyper mobs, and massive late-game challenges.
Your journey begins simple: gather resources, build your first industrial machines, and prepare yourself for what’s coming. But danger is always close—linger too long in one spot, and Trackers will find you. Defeat them to earn the mysterious Black Hole Matter, the very first step in a chain of progression that changes everything.
From there, you’ll unlock new tiers of Matter by taking down increasingly dangerous Hyper bosses:
- Craft with Dark Matter to push past the early game.
- Face the Hyper Magma Cube and claim Inferno Matter.
- Challenge the mighty Hyper Ender Dragon for Dragon Matter.
- Conquer the Hyper Wither and obtain the rarest Wither Matter.
Every victory opens the door to stronger gear, more advanced machines, and incredible automation. Collect souls, power up your Simulation Chamber, and push toward the ultimate goal: forging the near-mythical Perfect Matter. With it, you can craft devastating weapons, unbreakable armor, and legendary machines like the Infinity Matrix—capable of replicating entire Matters.
Extreme Monsters isn’t just about survival—it’s about escalation. Each step forward unlocks new dangers, bigger rewards, and a sense of power unlike any
