How do you beat mission 5 in Devil May Cry 3 special edition

In mission 5, there's two missions. One is defeating The Jester and the other is Defeating Agni and Rudra.

Defeating the Jester: This one is quite easy. I am a girl and I myself found it pretty easy lol. Well, basically, you have to just use Ebony&Ivory guns and just keep shooting the Jester and WHILE you are shooting him, move closer to him. This way, you're doing 2 things at the same time. So, once you've shot him and got closer to him, use your Cerberus(the chain thingy) and attack him. All in a sudden, he'll move away from you and start to defend himself in a bubble and use his powers to attack you. This is when you'll have to move around or jump to prevent getting touched by his powers aimed at you. After he has stopped, continue doing the same thing I told you above.

Deafeating Agni and Rudra: I've just defeated them somehow. This is quite hard. This part, you have to continously use your Cerberus on both of them, once you get the hang of it, then, it'll be easy as BUT one thing, when you fight both of them, don't leave one brother with long life and other one with short, for example, as you attack Agni and the life decreases, attack Rudra and get it's life to the same level as decreased as Agni's, this is 'cos when you only let one die, the other will use the brother's weapon and attack you, this will make it harder for you. So, when Agni's life level is about to die, start attacking Rudra to Agni's level. Also, prevent them from attacking you! This is by keeping short distance away from both. Also, when your life level decreases, remember to have extra green orb so you can gain it all again. :)
