Rule #1 - Shoot them in the head.
Rule #2 - Bring a machete. Works better for close encounters.
Rule #3 - Illegal narcotics are now your friends.
Rule #4 - Camp with Claymores.
Rule #5 - Get a dog. Very helpful for alerting you to a zombie breach. Just make sure he is obedient, otherwise you might end up with a zombie-mutt.
Rule #6 - Equip your dog with a self-destruct collar, just in case.
Rule #7 - Drive a truck. Preferably one with a mounted .50 cal.
Rule #8 - If you didn't kill it, don't eat it. You don't want zombie leftovers.
