I would like to see some sort of an armor crafting system. There are a lot of zombie books and movies that show survivors creating various types of zombie armor. In Max Brooke's "World War Z" the book not the movie, the author goes into detail about the US Government creating bite proof clothing for our military personnel to wear while fighting off the zombie armies. In The Walking Dead, characters have wrapped thick fashion magazines around their arms as a kind of shield, I remember one guy in season 3 or 4, whenever they were fighting the governor, use a jacket with the sleeves covered in a really thick layer of duct tape, making his arms bite proof. In "Rot & Ruin" by Jonathan Maberry the survivors use what they call carpet coats, they are literally carpets cut up and sewn back together as a bite proof jacket. There are many examples of this, and I think it would be a pretty cool addition to the game.
