The zombies in this game don't look scary enough

The zombies in this game look like super fresh just turned zombies pale skin, none have any damage on their bodies or look withered at all.

So what i am saying is that the zombies don't look scary enough. Their screams are scary for an hour or so until you get used to their waling.

Will the devs ever add more scary looking withered or mutated zombies in any future update?
