DMC4, but I'm on a crusade for gun only percent PART 1

similar to the DmC: DmC gun only crusade, I will be playing through and completing DMC4 on every difficulty with every character, and a special run where i am only allowed to use guns (Lady may or may not be the saving grace for gun percent) I will also be doing a special playthrough of gun only on LDK (Legendary Dark Knight) if I manage to beat the normal game with gun/buster only (because throwing enemies at other enemies kinda counts as not using a melee attack)
