I'm sure this has been brought up before but I think zombies with different body types should be added into the game. I know the developers are against adding special infected, but I think zombies that were more muscled, fat or skinny before they turned would add some much needed variety to the zombie population. Different zombie types could have their own unique attribute, such as fat zombies having more HP and being slower, muscled zombies hitting harder and more likely to bring you down and skinny zombies moving faster. This would also tie in with the obese/extremely underweight perks, with the player model visually showing these traits.
