Vampire Apocalypse

You're hiding in an alleyway behind a dumpster after going on a supply run. You hold onto your bag of food and drinks as you pull down the apartment ladder. The sound draws unwanted attention, and the vampires start to circle. "I smell human!" You're now cornered, and you close your eyes. You hear shrieking and see several humans killing vampires. Austin holds his hand to you, "Come on, more will be here soon. We have to go now!"
