Zombie Survival Tip #1 -> Avoid Crowded Places - Places that were crowded in the world before zombies will still be crowded after--with the undead.  You need to avoid crowded citys, shopping centers, and any areas where large numbers of people regularly go. Survival in a zombie infested world is not about weapons and killing mass numbers of zombies, it is instead about avoiding confrontation.  When one mistake can be your last, dealing with the least number of undead you can gives you the best chance for survival.  Stay hidden, avoid crowded areas, and be safe.
