Dawn of the Dead
At the begining of the game (Iceland), get to the second checkpoint and turn the lever next to you, then go through the door and up the pole so the guy comes to the edge (kill or knock him out, really doesnt matter now does it?). After that turn on your heat vision then go a little further and look up, you should see a guy there. Shoot him in the head and continue, when you get to the part with the guy you shot he will be standing there but it will say he is dead (upper corner box says pick up body), weird isnt it? You can even walk through him but it wont do anything and he just keeps looking around, "Hey look a fly."
