You use the flamethrower on the plate, and the hole expands at the same rate as the plate! Eventually it is large enough to fit through, and you hop through. You can see the helicopter ahead! You're almost home free!

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?
