You are in a mall when the zombies attack. You have: one weapon, one song blasting on the speakers, one famous person to fight alongside you. (Weapon can be real or fictional; you may assume endless ammo if applicable. Person can be real or fictional.)
Weapon: A really big gun, automatic, with unlimited ammo. I know nothing about weapons, or I would be more specific. :~P
Song: "Uprising" by Muse
Famous Person: Jack Harkness. Period.
