Only head shots count, they attack in hordes, and are attracted by noise. My zombie gun is the one in the middle, at least until I retire and have to give it back. Then I'll have the fun of picking something else.
I enjoy all the zombie stuff. I can't wait for the next season of The Walking Dead, and am looking forward to World War Z (though the alleged PG-13 rating makes me wonder).
I'm glad the gun and ammo companies are cashing in, and I couldn't possibly care less how it makes gun owners look. Whoever doesn't like us isn't going change their opinion based on the availability of zombie ammo, and if it brings in younger shooters I'm all for it.
I'm 53, by the way, and have been a zombie fan since "They're coming to get you, Barbara .........."
