Edit: after a few years playing many Zombie games i must say state of decay is one of the backward games out there, just play Zomboid and you have everything you ever want like:
-Finite Zombies
-Looting
-Building
-Character Customization
-Multiplayer
-Many Mods
-Weapons on mass
-Brutal Zombie Chases
-Cars
-Car Repairs
and More is to Come in an mega Update like NPCs, Animals "farming" and new Crafting system
