Mildly derailing, but I’d like to see animal breeding and ability to have litters/young added in, for helpful and harmful animals alike… Would be good destroying spider eggs and domesticating chickens and cows (whose constant noise would obviously draw zombies…)
Also the ability to name tamed animals just like vehicles… Just thought it’d be a good dynamic, espescially if more domestic and farm animals are added… Zombies banging on the door and you’ve got a mother cat (Floofles), and her three babies (Tash, Ween, and Chuck Woolery) to think about defending too… I’d just like to be able to go on forums and tell the tale of the zombies that mauled poor baby Chuck Woolery…
As far as other animals… My current most hated living thing is god-awful bedbugs Doubt even a nuclear apocalypse would do them in, they’re basically roaches that don’t want anything but you… Would be terrifying, though, to wake up in the morning and find six or seven cat-sized bedbugs gorged on pints of your blood (you’d wake up woozy from that one)…
Really, though, most bugs and wildlife that spring to mind immediately are the stereotypical over-used ones, some of which are already in… (nuisance/phobia/poisonous creatures like spider, snake, scorpion, roach, rat, bat, or any animal capable of winning against a human in one-on-one combat, like dogs, cougar, bear etc)…
What really needs done is some good dynamic action each creature participates in (dogs are peaceful until five+ are around, and then they form a pack. Bats that infest houses during the day, predator animals lying in ambush in shrubbery, spiders that hide in cabinets or dressers). One that me and some other folks discussed that’d be good are feral pigs… Are alligators or crocodiles in (since natural water sources aren’t dangerous enough already!)??
Addition of a large zoo, or endangered wildlife preserves/dog-training facilities/animal pounds/kennels (maybe even taxidermist shop) would be helpful as well… Zoo/circus alone adds realistic reason to bumping into the rare stray tiger or gorilla or elephant…
