Saving Vergil | 12: Under Siege DMC: Devil May Cry Guide

Only now you begin a normal game. Your first task is defeating a new Butcher. As you probably remember, crucial thing is to avoid his attacks with chainsaws. Aim at his orange bump.

Be careful at the end of the encounter, because Butcher will get furious. Move away before he explodes. Watch a new cut scene with Vergil and Kat. You'll get to know that you'll have to fight in Limbo while they'll be busy deleting some data.
