This is the only good boss fight of the game.
And no, I'm not doing pistol/knife only for the whole game but it's just to showcase how to deal with his move set and how to punish his weakspot.
I set to level 3 since on hardcore that's the highest level you can upgrade to in case you're looking to apply this on hardcore.
