Start a new character and find a white rarity hand cannon which can hold three bullets. This will be your weapon. You may not use special weapons, heavy weapons, grenades, melee, and definitely not supers. Also, no aiming down the sights. Sighters are filthy, cheating noobs. If you can't get at least a 5.0 kdr with this loadout, you're a -blam!-ing scrub and should go play COD.
