EPIC FAIL
You clearly know nothing of zombies. you probably just watch the movies l=L, ive done the homework buddy an mp5 and a shotgun would do well, you always need a primary and secondary weapon.
There are many types of zombies
Type A- The solanum virus, the virus travels through your bloodstream to the brain once their it infects your brain and destroys most of the frontal lobe and weakening and strengthening different sense. The virus only needs the brain to thrive so destroy the brain destroys the ghoul. decapitation works but its still alive, watch out for the teeth! Type A's also feel no pain fear or can be educate or think in any WAY, besides me hungry UGGGGGGH and no they dont eat brains they eat flesh.
Type B- They can run fast! not super fast but they can run, They feel pain. and you can make them bleed out so if you say shoot its heart it will die. anywhere that'd kill a person would kill a type B. Did i mention They LEARN, Not much though, Sat they accidentally fire off a round, from a gun, they'll try and do it again and again. They wont have the fine motor skills we do but they'll still shoot in your general direction chances of getting hit are slim.
Type C- Basically a disease from another planet so its unknown.
and lastly Type D- Theres no more room in heaven or hell so they come to earth, if you die in any way you become a zombie and you cant kill them because they already died. so no room in heaven or hell..... yeah
