The Sculk Horde unleashes an ultimate end-game challenge that will push you to your limits. Once triggered, the ancient Sculk Horde awakens from its slumber, hungering for the assimilation of all life forms in your world. This highly intelligent and adaptive horde will stop at nothing to grow stronger and more powerful, making it your sworn duty to eradicate them before they consume everything in their path. Are you ready to take on this perilous mission and emerge victorious?

A Bioweapon gone wrong, this mod adds a hostile fungal infection to your peaceful Minecraft world. Face off against bloodthirsty mutated mycelium beasts as you fight back against a dormant bioweapon reawakened at the smell of fresh blood. Reemerging from centuries of slumber, this ancient project of a bygone era is ready to retake the world. Fight tooth-and-nail against an infection built to work against mankind, and try to get your own foothold and uncover the secrets of the infection's backstory before the infection takes over.
Infection: As you start your world, you'll find infected humans emerge, ready to spread the infection. Their bite inflicts Mycelium Infection, and upon a suitable host falling, they will rise again, as a pawn of the infection. This... thing is a bioweapon, built to eradiate mankind, and will only infect other humans.
Mutation: As the horrific infecteds eat and consume more biomass, they'll begin to undergo an evolution, mutating into new stronger forms, with the sole goal of elimination... and the reconstruction of a fallen hivemind.
The Hivemind: The infection wishes, beyond the culling of mankind, to rebuilt their hivemind. They have improved A.I. compared to vanilla mobs, and will attempt to group up into hordes, request back-up, build a hierarchy, and even begin the reconstruction of the hivemind, an interconnected network of minds. Be prepared, for as the infection begins to take root in this peaceful Minecraft world, you might just encounter horrific constructs of fallen humans, constructed by the contorted minds of their fallen brethren.
Adds everyone's favourite alien shapeshifter to Minecraft 1.20.1!
Requires AzureLib and FromAnotherLibrary (and Fabric API if you're using the fabric version)

This mod has a unique take on the concept of invasion and infection mods:

-The mobs have a consistent presence - they cannot spawn or despawn randomly. They spread through your world like a real organism with a consistent method of reproduction and never "cheat."

-Survival is the focus - everything is balanced and tested for survival mode with no other mods installed. If something is unfair/unfun, this is not intended, please report it.

The Flesh That Hates

Experience the true horror behind an assimilating infection!

Face the unstoppable carnage that has been awakened in the world of Minecraft. You don't know exactly what it is, you don't know how strong it is, you don't even know if you'll be able to fight it back. But one thing is sure: THE FLESH MUST DIE!

Infect your world!

The Flesh That Hates will infect your world. As soon as you hear a terrifying hum, it indicates the birth of a new Incubator. The longer an Incubator exists, the stronger the infection and the Incubator itself become. Fear will not save you, escape will not help, they will find you anyway.

Incubators!

Incubators are the beginning and the end of the entire infection. Incubators are capable of evolving, creating armies of flesh creatures, and much more unpleasantness.

Biomass

Biomass is a dynamic difficulty system which will affect the entire infection, punishes the players who ignore the infection and rewards the one who fight it. The Flesh will gain Biomass by doing different activities. Biomass enhances the flesh creatures in various ways, and it's up to you to find out how!

The Flesh has many ways to acquire biomass, at least through the killing of mobs.

Fight it back!

However, the Flesh will lose Biomass by destroying it: Breaking blocks, killing flesh creatures or killing Incubators. Each action will vary differently in how much Biomass you take fron the Flesh. There's also a way to fight the Flesh back, but you'll need to find it. Don't worry, it is actually quite obvious
