Nice shot! You fire at the weasels, and each time when they fall, your bullet falls at the same rate, hitting the weasels dead on. Soon they are all dead, and you breathe a sigh of relief. You continue toward the helicopter landing zone, map in hand. Soon you can see the wings of the helicopter just up the road.

You hear a loud, constant pitch scream behind you. As you run, the scream seems to be getting lower in pitch by a slight degree. Figuring it is a screaming zombie, you decide that if it is running away you can safely continue on. But if it is coming closer you should hide in the bushes. There might be horrible things in the bushes, but surely they are better than a zombie. What do you do?
