For killin' zombies? Ain't they dead already? How do you kill dead things, anyway?
I always tell my friends they will know the direction I am headed by the way the headless burned corpses are pointing.
Decapitate, point headless body like an arrow set on fire. It’s the only way to be sure. Nothing without a head is a threat anymore. Thermite > white phosphorus > napalm in this case.

Double tap.
