It was the end. The zombie apocalypse had wiped out over half the population, leaving stragglers to survive on scraps of remaining humanity. The streets are either run down or infested with clickers and runners.

As you were fleeing a group of runners, you trip over a wired trap, causing the runners to catch up with you. Right before they reach you: Bang. A shot rang out, diverting them away from you.

As you look up, you see a hooded man with a 9mm. He had saved you.
