When your at the main screen hold down L1+L2+R1+R2 and rotate the left anolog stick. You should hear "Devil may cry." After once your at the last boss. Which should be virgil #3. Go onto mission selact and press L1 and R1 in until you see dante with all of his clothes on and a purple flame on him. Select him and pick the mission that vergil's on and your style quicksilver or whatever it's called. Equip agni+rudra and bolwulf or whatever that's called. Then when you fight him use your devil trigger(dt) and your dt will never go down. Also have at least 2 vital stars L your first time battling him and 1 your second time. So put on dt and have agni+rudra ready. Then use your ability to slow time and kick his but. Again your dt will never go down. When he uses his dt just attack until he jumps and then run. Just keep attacking him even when he's not in dt. If take's down your health then use you vital stars. Only when there's 2 bars or lower do you use one. Otherwise your wasting. You should destroy him. Dill man.
