Infection Of Unhuh
by Unhuh
Infection Of Unhuh is a Forge mob mod in which mysterious beings called Unhuh spread a world-changing infection that grows harder to stop over time.
What it does
Players meet the Unhuh, extremely hostile entities that infect everything around them and turn the world into something else. Once the infection starts, it spreads, evolves and becomes harder to stop as days pass, and fighting back is only possible when a player is prepared. Start Mob beings are meant to infect the early stages of a world, and they infect ordinary mobs, some of which evolve into Mutant Mob enemies.
The mod lists more than 60 mob enemies, more than 10 mini bosses, more than 100 items and more than 50 achievements, along with a Plan Phase system, world infection and new structures. A Class Core system lets players change class through a Creative-exclusive item, and a Red Unhuh Apple can grant immunity to the Error Unhuh effect that triggers the infection. The mod runs on client and server, so the server and every player need it, and it is published for Forge 1.20.1 with 3.4.9 as the latest file, under All rights reserved.
