Rotted
by TheASEStefan
Rotted adds new zombie-type creatures to Minecraft, with animations, sounds and attacks meant to look realistic, for players on Forge 1.20.1 and 1.20.2.
What it does
The mod expands and revamps the zombie branch with several new zombie types. Rotted zombies use a more involved AI than vanilla zombies: they are weaker to fire, they follow players, and they stay in groups. When a player hurts one of them while others are nearby, the nearby zombies react and come after the attacker.
Difficulty can be tuned in the config file, which controls the health and damage of the rotted zombies for players who find them too strong. Geckolib is required and must be installed alongside Rotted on Forge. The mod is compatible with many other mods and runs well with shaders, although some shaders or mods may change how the mobs look. Rotted runs on client and server, so the server and every player need it. Files are published for 1.20.1 and 1.20.2, and the latest Forge build is 1.20.1_1.0.5 from November 15, 2023, under the MIT License as open source code.

Use cases
Who it’s for: Players who want more varied and more dangerous zombies on Forge 1.20.1 or 1.20.2, and server owners who run the mod with shared worlds.
How it compares
Zombies are strong together is a server-side only Forge mod for 1.20.1, released under All rights reserved and not open source, so players join without installing it. Hard Zombie runs on client and server for Forge files 1.19 – 1.20.6 under the MIT License, but it is not open source. Egg's Zombies is also client and server on Forge 1.20.1 under the MIT License, and it is open source. Rotted differs from these by targeting 1.20.1 and 1.20.2 on Forge only, with the MIT License and open source code.
