((You're walking along the long, abandoned city of Atlanta; it's nighttime and very dark out. Suddenly you hear a horde of zombies. You get scared and run away to one of the big buildings in the city. You run all the way to the rooftop, and once there, you block the door up with anything you can find, and you turn to see a woman holding a double-barreled shotgun right at you.))

The woman looks very terrified, and she's shaking while holding the gun right at you.

Who are you? Tell me now! Why are you here?
