Welcome to Apocalyptic Difficulty! This mod makes your game harder by implementing evolved zombies and new entities.
Enraged zombies:
A 10% of the zombies are Enraged, they have flame particles, more health and are overall stronger than the normal ones, watch out for them! A 75% more zombies spawn anytime too!
New entities:
Zombie Golem: This guy is a pretty tough zombie, it will grab another zombie, and will throw it at you! 
Causing an explosion
Self-proclaimed chosen zombie: A silly zombie that holds a huge excalibur, be not afraid though, It's a selfish coward, and it will attempt to run away with a zombie-helicopter on low HP!
Comically-sized Zombie Golem: as It's name says, it's a bigger version of the zombie golem, this one is a boss though that usually spawns in the END, it is capable of grabbing you, cause earthquakes and etc
Elite Zombie Caller: Despite missing half of it's body, it calls other zombies, some being explosive! To 
attack you.
