Zombie Night Hordes

This lightweight datapack adds zombie hordes at night. When night comes, all zombies become faster, and if you kill too many, you will summon a horde. Careful though, they can smell you from very far away and will find their way to you. They aren’t slow either. If you do manage to beat or escape the horde, you can breathe easy, only one will spawn every night.
This datapack is best experienced with zombie apocalypse mods or modpacks to add to the atmosphere.
