@dude33369 You have to shove the shotgun down chuck norris's throat and shoot to stun him, then run as FAST AS YOU CAN, it pays to have a high speed stat at this lvl, and it also helps if you have stun grenades to stun him while you run away lol
DEFINITELY needs more potions, you get so many things out of chests that you dont need and nothing you DO need, other than that, it needs an autosave feature for after each floor and i think you should probably regain some health for free once you get to a shop, those improvements would help out a lot
