Will zombies in the city be any less starved than ones in the countryside, since there will have been more food for them, or will the distribution of healthy/normal/starving zombies be the same for all places?
Also: Will different footwear have any effect on your stats? (Such as trainers allowing you to sprint better, but hiking boots letting you stay on your feet without tiring for longer, army boots letting you kick harder, etc.)
Zombie health has nothing to do with 'food' intake. Zombies don't actually receive any nourishment from your flesh. They still rot.
It's sad, really.
