How would you even kill a zombie? Magic?
I heard it takes brain dmage to kill a zombie, and a gun would do just that. Except, do they even have brains? I mean, zombies are the living dead.
Well, most current zombie theories say that a zombie could be produced by a virus that reanimates dead bodies, or affects peoples minds, like rabies, in both cases they would probably need brains. Now, if they were zombies proper, summoned by a necromancer and bent to his will, then they'll keep at it 'till the necromancer is killed. Either way, a shotgun and a flamethrower are the way to go, a shotgun'll take them apart as quickly as possible and in the right order, and as for the flamethrower...I don't know, but fire and explosions are very satisfying.
