Finally got around to playing Postal 2 after snagging it on the cheap a few months back.
How the hell does the Krotchy fight work? I shot him with my gun a lot, but he seemed immune to bullets. I set him on fire, but it did a grand total of 7 damage out of his 500 health. I figured maybe he worked like Metalman, so I threw a Krotchy grenade at him which killed him more or less instantly.
How is the fight actually supposed to go?
