Red's Mutants
by RedSkeleton
Red's Mutants brings three hostile mutant creatures into Forge worlds for players on Minecraft 1.20.1, the Headcrab Mutant, the Spitter Mutant and the Tall Mutant.
What it does
Each of the three mutants is built to unsettle a player rather than fight on equal terms. The Headcrab Mutant is a fast, skittering creature that lurks in shadows, drawing on the look of its Half-Life source. The Spitter Mutant attacks at range by spitting acid, and the Tall Mutant is the largest and rarest of the set, a hulking beast that keeps coming until it is defeated.
The mod is for survival and adventure players who want more horror-style threats in their world, and for server owners who want the mutants to appear alongside their existing mobs. Its creatures are animated with Geckolib, which must be installed alongside it on Forge for 1.20.1. Red's Mutants runs on client and server, so the server and every player need the mod. It is published only for Forge, with a single file for 1.20.1, and it is released under All rights reserved, so it is not open source.

Horror survival worlds
Players who want their survival world to feel more threatening can add the mutants as tougher encounters beyond vanilla mobs.
Adventure maps
Map makers can place the mutants in scenarios that rely on the tension of a creature hiding in the dark or a relentless pursuer.
Who it’s for: Players and server owners on Minecraft 1.20.1 with Forge who want hostile horror-themed mobs, and who are willing to install Geckolib on both client and server.
How it compares
Mutant Addition Mod is a Forge mod for 1.20.1 released under the MIT License, and it can be installed on either side or both, so neither the client nor the server needs it. Nocturnia is a Forge mod for 1.20.1 that requires both client and server, with All rights reserved licensing. Mutants and Zombies is a Fabric, Forge and NeoForge mod covering 1.12.2 – 26.3 with the same client and server environment, but Red's Mutants is Forge-only and limited to 1.20.1.
