This may sound like one of those posts asking for zombies in general to get smarter, but this post is a suggestion for a different kind specific of zombie.
Let’s start, this turn has had its brain mutated, although it’s even dumber than an NPC has certain different abilities that make it smarter than other types of turns.
A hunting zombie. .
This zombie can spawn anywhere, if he is wandering around and seeing players or some construction he will be gone for a while, but he will come back attracting a larger group of turneds to help get food and invade.
A sneaky zombie
This zombie is weaker than the others, so it prefers not to attack alone and not even ahead, this zombie prefers to hide and wait for the player to be distracted to attack,if injured or disadvantaged he may run away.
These zombies can handle certain things like sticks, stones, frying pans and hammers, they don’t use them to attack directly, they just throw it at their target as a player, or something they want to break like a glass window.
They prefer to be in larger groups with strong zombie types, getting a kind of escort and protection.
