I'm alternating between playing DMC2 on hard and continuing to play DMC3 on hard. Furiatarus got me worked up so much with that suctioning air current, that even though the moth was quite easy later on, I just couldn't bring myself to start the mission with first Bolverk fight. That crazy skeleton will turn me into a shish kebab, I can just see it.
At least Bolverk looks stylish as all get out while doing it. He's probably one of the coolest bosses in the game, honestly.
