With the way the current map looks, it’s pretty suburban looking. However later on in development I suggest the map being split up into 3 large zones representing Urban, Suburban, and Rural environments.
Rural: Low amounts of loot in exchange for low zombie density, but higher amounts of potentially dangerous wildlife. All you’re going to see are rolling fields, farmhouses, gas stations, as well as the occasional lab, bunker, or other secret stuff you’re going to found out in the middle of bumf&%$ nowhere.
Suburban: The way things are now. Small towns and wilderness spread across a large area along with all the other goody bits.
Urban: Insane zombie density in exchange for enormous amounts of loot to be found for those brave or crazy enough to fight through an ocean of undead. A late-game playground for powerful characters, where clearing an entire urban city will be a feat worthy of song or squelching shits of terror as we all lay eyes upon the unstoppable behemoth who did such a thing.
I’m tired.
