Had to post
A good name for these would be “biders”, zombies smart enough to understand the weaknesses of the average human (being surrounded, starving to death, etc) and will wait on you to slip up or sleep, basically… Could start spawning after five days or maybe a season to explain how they developed human-hunting skills… They could jump in any time you get pinned/trapped or blinded, or maybe when your wounds reach a certain severity or move speed gets low, or combat stats drop too low…
Any way to make an enemy target structures specifically, like setting traps off on purpose, breaking windows/barriers, pelting buildings with rocks, disabling traps and sabotaging vehicles, damaging crops, things like that… Guess they’d only be vandals at night though, and then they could hide away inside a nearby structure during the daytime and will return to cause more property damage every night until dealt with.
(Here’s the copy-paste of my original idea, though it was for Project Zomboid:
Zombies called Talkers? borrowed from I Am Legend book, where a zombie still faintly remembers you from its past life and becomes fixated on you, but flees/hides when hunted (can study structural weak points and target them, can shout (your name) in the night and wake you up and decrease mood (why you’d want to kill it) can maybe even use advanced tactics like pit traps or fire (poorly) if left alive long enough) These could show up in emptied towns you keep a safehouse in to add some spice to your otherwise threatless existence…
Also, reading this thread is the first thing to make me even realize all Cataclysm characters have a strange 360 degree eyeball ring around their heads
I guess having a facing would add tension, but we’d need to be able to walk backwards, sure there are other technicalities involved I can’t think of 
And lastly, please forgive me for wishlisting! I’ve apparently got a problem
But I do believe that getting an idea out there, even in a crude form, can land it into able hands where it gets fleshed out into pure magic… So beware my wishlist!!
Skinnies? suburban country zombies that have only been around other zombies
their whole zombielives and have never got to eat, making them emaciated
and dry, thinner and faster than other zombies, but easier to kill as well…
(skinnies would be dangerous on fire…)
Blood bottles as attractants, to be used to bait zombies into traps, or
distract to escape
Wilderness zones like natural orchards/glades and freshwater pools (plus associated dangers)
Live traps/snares/cages for hunting (and maybe zombies too) plus taming creatures based on survival skill 
Celebrity zombies? (elvis/fictional or spoofy movie stars, or even local weathermen/personalities/
mascots from businesses)
Diablo type boss-augmented enemies?
Assorted fireworks and firework stands?
Aaaaannd… BACK ON TOPIC, GO! WEEPING ANGELS!
