OOUndeadExpansion
OOUndeadExpansion turns the animal life of your world into part of the undead threat.
Zombies and zombie animals can infect supported animals, creating hostile undead variants with their own behavior, visuals, and configurable stats. Infected animals use vanilla friendly yet deadly abilities and can easily become a formidable source of danger in the world. With the right items, they can also be cured back into living animals.
The mod was commissioned for the Ominous Odyssey modpack and is built for hostile survival gameplay, horror-leaning packs, and worlds where infection should feel like an active part of the ecosystem.
