you need to cut his head off??? zombies are still humens, the need blood to life, and btw, you could take the shotgun too, i think it hurts much more then a basball bat... oh you think shotguns can only shoot? idiot -.- and the home... uhm a good survivor can call his home fortress now, so you shouldn't go to the mall, a big open place, where could be millions of zombies.
If you make a zombie test, you should think logic, realistic and may you shouldn't belive all what you saw in the TV.
