People think it's tricky for this Boss Fight, but i managed to Defeat Him in 3 minutes!(also there's some invincible frames on Hansen that i can't deal damage to him. sad!) i have Apogee Sandevistan and Errata(+ Neurotoxin Knife)
i found this useful to survive is to take cover and flanking around the Football Team Statue! of course the Boss has two phases, the first one is he wields his Machine Gun... then the phase two as Kurt is resorting into only melee attacks and throwing knife attacks, it gets a bit tricky... the unavoidable grab/knife attack animations on player is kinda annoying.(but in experience, it didn't bother me)
