don’t use guns unless you need to, they attract the damn things. Don’t go running in there, or you best be prepared for a struggle. Zombies feel no pain, and have no limits to their body like humans. They will grip you until their fingers break, and will continue until you bleed. They will claw at you until their nails fall off, and will keep doing it. If one manages to fall on top of you, they will use all their weight, and are near impossible to push off. Whilst trying to kill one, always aim for the head. Also, don’t think “Oh, but that will hurt them badly.” That will only make you insane.
They don’t feel pain. They don’t bleed. They don’t die.

Also, here are some of my last tips:

Don’t throw a grenade into a crowd of zombies. The dense crowd will only muffle the blast, and the immense amount of bodies will only reduce damage. Travel in small groups, defend in large groups. Make sure to have a vehicle, most likely one with passenger seats, one that travels far, and one that is relatively silent.

Hope this helped, trust me, I’m an expert. Also, visit our website, http://www.zombieresearchsociety.com for more information of zombies, merchandise, and social activities.
