"Shoot them in the head!" I shout, as I hand out ammunition.
I don't know why the dead have risen up, but thanks to years of zombie films and TV shows, I know exactly what to do.
A flurry of shots ring out. "It's not working!"
I look out at the approaching horde of undead. Did we all miss? No, I can clearly see bullet-holes through some of their skulls.
"Destroy their brains completely!" I yell, releasing a spray of bullets that decapitates the nearest zombie.
"I think we're in trouble..." someone says, as the headless corpse continues to advance.
