ok well for close range your gona wana use a shotgun or a assualt rifle with a high rate of fire...the military shotgun or the ak-47 is good for close range...pick a gun with power and fire rate of accuracy because at close range it doesnt really matter...alot of people at close range want to bunny hop but dont its just annoying move around and crouch but keep moving because its harder to shot something moving than if it was still...
