What kind of zombie we talking about though? Resident Evil T-Virus/C-Virus? Dead Island mutated prion? Left 4 Dead Green Flu? Dead Space Necromorphs? It does matter you know.
Blades for arms, spitting acid, can survive in the vacuum of space, can make themselves explode, must be dismembered to kill them and they come in all shapes and sizes from the size of a child to the size of a moon.
The zombies will wish I was that polite to them.
