This is a simple datapack that replaces most overworld mobs with different zombie variants. Creepers, Skeletons, Strays, Spiders, Cave Spiders, Endermen, Guardians, Elder Guardians, and Witches are removed and replaced by zombies. This datapack also includes blood particles to make the gameplay a little more fun and brutal.
It's recommended to use Tissou's Zombie Pack, and Fresh animations, as well as a gun mod of your choice to make the experience way more fun, but it's not required.

Going to the nether or end with this datapack is not recommended at the moment.
