Basically, awesome guy with lame teammates who only fought melee.
So, what Hiro and I did was only fight him with melee.
Only, his teammates and our teammates weren't cool, and fired at him/us when were were having epic duels.
Hiro also lit me on fire once when I was having an epic duel with the guy, but I didn't mind since he was going for an achievement.
In one battle, I decapitated him with my sword. Most of the other times were fish kills [beating him to death with a mackerel in news paper].
