#4 Six Shooters

Sure they can pack a punch, but they also create a false sense of security that Zombie hoards love to take advantage of. They're aware that some of them might get a golf ball sized hole in their head, but it can only fire 6 times and it takes almost twice as long to load than a clip based pistol.

#3 Flat Terrain

I don't care about the "updates" on the Zombie mythology, Zombies can't run or move fast for that matter, period. So given their diminished mobility there's nothing more kosher for a hungry Zombie than an obstacle free surface for them to slowly pounce on your tasty ass. They can't handle going on a steep downhill terrain very well tough, flat or not.

#2 Moan/Grunt (Not "stuff" but they like it anyway)

Since they are the walking (I know, not always) dead, focus on the "dead" part, their brain usage is reduced to an average of 0.5% to 0.9% capacity. This pretty much renders their verbal communication to "grrrrowl", "ahhhhhhh", "hmmmmm", or the ever popular "bbbbrrrnnnsss", etc.

What you didn't know is that they love to do it, oh yeah, they can't get enough of moaning and grunting. The only time they won't do it is when they're sneaking up on a potential kill. Surprisingly they are able to sneak up on people, haven't you noticed whenever someone thinks they got away from them, the second they feel safe and turn around they find a gory death by a quick chomp from a Zombie.

#1 The Living (You)

There should be no debate on this one, I think everyone can agree that the main purpose in lif... death for a Zombie is to eat, taste, maim, devour, gut, and in a very few cases, fall in love with, a living human.

To sum it up, to them you're just a source of nourishment with limbs, limbs that they seem more than happy to chew or bite off (more on that later).
