Slyer109 is spot on. When I started playing, I admit I was a battlefield/splintercell type player. I assumed I could crouch run everywhere at first. You can't. You have to prone and you have to be patient. If there are too many zombies, and you're unarmed, chances are it's in your best interest to move along. Also, the more you play, the more you realize what buildings are more likely to have what you want. Along the railway stations there are sometimes hatchets, for example, and they are pretty easy to sneak onto. And finally, listen. If you approach a building and hear zombies close, don't go in. You have no weapon and you're just going to end up getting maimed tripping over the door frame. Door frames kill 95% of beginner survivors.
