It was the end of the world. Zombies. Zombies were everywhere eating any survivor they found. You and your girlfriend were running down a street from a horde of zombies chasing you both. You both ran and ran until she saw a abandoned shack. She pushes you inside and locked you in.

"Stay in here. I'll lead the zombies away. I promise ill come back for you."

As soon as she said that she turned away from the door and yelled at the zombies grabbing their attention and chases after her. She ran.
