Old Mutant More

The mod adds a large group of new mutant mobs inspired by the Mutant Creatures and Mutant Beasts projects. Some are found naturally in the world, while others are created with new items such as Formula Y Compound Z. Most of these mobs are tough opponents, and defeating them yields strong items and rewards. A number of new advancements are granted through specific special means.

The Mutant Husk is a stronger version of the Husk and resembles the original Mutant Zombie in behavior. It can spawn in the wild, where a small share of Husks become Mutant Husks. A config file can change how it looks, giving it a more cactus-covered appearance, and can also alter its behavior. Its ground slam sends a shockwave through the area, and its sand throw deals heavy damage and blinds the target.

The mod requires Geckolib, which must be installed alongside it. Old Mutant More is client and server, so the server and every player need it. Files are published for Forge only, for Minecraft 1.16.5. The mod is All rights reserved and is not open source. Some mob animations do not play correctly, an issue the author notes cannot be solved with the GeckoLib in use. The author has stopped issuing updates, and the later Mutant More mod is a separate continuation.
