You wake up in a dark forest, with no recollection of when or how you got there. You look around, seeing nothing but trees for what seems like miles.

As you come to your senses, a sort of primordial fear washes over you, though you can't explain why. The only thing your brain is telling you?

Survive.

You hear some sort of low, guttural growl behind you. You whip around only to be face-to-face with what appears to be a zombie. You don't have much time to think, only react. What do you do?
