So for maybe the next update, i was thinking of it being about more entities, like lethal company creature feature and the repo monster update. Along with new western buildings (such as the big double floor buildings) from some shows such as Sherrif Callies wild west, which the small ones can stay and exterior assets. This is because theres already a bunch of zombies and animals and to make it like the others games such as lethal, repo, mimesis, etc. heres the entities what I had in mine (make such to block the text for spoilers) also the * means their behavior is using the mechanics like never before seen:
1.spider: drops onto a players head & bites. will show it dangling on the UI and the webs will tell you when it spawned.
2.bat: sleeps upside down in buildings, wakes up if it hears any noise. If it wakes up, it will do a sonic scream dealing lots of damage.
3.Train jacker: sneaks into the front of the train and starts it.
4.sniper: hides in or behind assets sniping a player it targets.
5.buff zombie: a tougher version of a regular zombie.
6.Infected zombie: bites when it gets close to you or throws a syringe at a distance to infect & turn a player into a zombie.
7.baby zombie: faster and smaller version of a regular zombie.
8.Blind entity
9.sight mechanic entity (like the bracken from lethal)
10.a entity that doesnt like sound
11.a entity that doesnt like light
12.Robbers (like the hoarding bugs from lethal and other entities that behave like that in the other games)
13.sandworm (like the worms from the other games like lethal company)
14.a weeping angel like entity

the others that i set aside for another update:
1.vulture
2.zombie that summons lightning
3.mummy
4.frankenstein
5.zombie that has protection against sunlight
