In BO2, the difference between each map was clear

You have 3 types of survival maps on Tranzit:

-Bus Depot (Most barebone experience, only the box and some wall weapons)

-Farm (You had the 4 original perks and the box, etc)

-Town (More perks and the addition of Pack a Punch)

Those type of changes made each survival map standout in BO2

What changes could be done in BO7 so every map feels different and its not just a different setting?

I know there's already some differences between those maps like the spores in Farm or only having traps in Farm and Exit 115 and not in the cosmodrome

But these little differences are not enough, for a instance they could change the special enemies like instead of having bears in cosmodrome, why not use uber klaus? or dopplegasters appearing in exit 115 earlier and more frequently
