Vanilla zombies are boring. All they do is just stick out their arms and swing them at you. Nothing special
Now it's pretty much the same, but with more life put into it.
Better Animations
All animations are made with the intent of making it look more like a zombie, while barely keeping that vanilla style.
More bloodshed
Everything, from the sounds, textures, and animations feel like rotting flesh.
Faithful
There are quite a lot of variety* in the skins and yet none of them will ever look modded in any way, shape, or form.
*there aren't many skins in the early stages of this resource pack, but skins are added every update!
--> Requires optifine for vanilla players! <--
