Stop me if you've heard this one before. It's the middle of the night, and the streets are deserted. You're trying to get to your destination, but suddenly, screams fill the air and the ground shakes beneath you. A horde of creepy figures is headed your way, and though you run as fast as you can, you are overwhelmed. The crowd tramples over you, and you black out. Nope, it's not Left 4 Dead 2, it's just Black Friday once again!
