Revolver/Pistol, Sniper Rifle, Shotgun and Melee knife. I like the firing rate of a revolver/pistol for close range encounters. Long range sniper rifle.. my most favorite area of armed combat, helps keep a safe distance. Shotgun for arc damage just encase I have to kill more than one close encounter. Finally Melee knife, for a quick and silent kill.. remaining undetected by possible surrounding hostiles.
