@ Look for anyone carrying a Zombie Survival Guide Handbook. Just be mindful of the constant 'I KNEW THIS WAS COMING!' crazy rants that this person is most likely to splew out.
@ Run! (Silently, though) Stairs are your friend, zombies will often have trouble with stairs and can easily be destroyed, you must cover all potential openings in the house with sheet metal and wood on your side of the window for added support. If you don't run, expect to be eaten alive by your former friends and neighbors.
@ Possibly the smartest thing you could do is sit tight, watch your favorite soap opera, eat everything you have in the kitchen and try to ignore the never ending pounding on the walls, doors, windows and some shrieks and slaughtering sounds coming from the outside.
@ Walk into a dark dark room or mysterious building. There will always be zombies in there, ALWAYS! If you do go inside, usually about half of your group will be picked off by the zombies and other crap that is waiting for you inside.
@ Follow the sound of a woman crying. You will eventually find a woman in ragged clothes crouched in the corner. If you poke her or shine light at her, she will turn around, and she will always turn out to be a super zombie-bitch who will then proceed to rip you into 54 equally sized pieces.
@ For God's sake people, how many scenes in zombie movies do you see one of the characters getting killed because they were standing in front of a window? Never sit in front of a window, your also walking into a fatal cut-scene at any moment.
