Primary:d) Shotguns are the strongest out of those four so I'd pick that for my primary.
You don't want a rocket launcher or anything explosive because
-it doesn't hold enough ammo
-in close combat you will blow yourself to bits
-chunks of zombie would fly everywhere
Secondary:c) I would pick the silenced pistol, just in case I don't want to alert the zombies. :p
Melee:b) I want a fucking nihonto or whatever that second japanese sword is. A chainsaw is too heavy and a baseball bat is inefficient.
Gadget:d) I want a swiss army knife for sho

not sure what a rope would be used for..
Vehicle:c) I WANT A FUCKING TANK NEED I SPEAK MORE? and what is up with the blow up boat at the bottom :dumb:
