At the Ballroom, you will be pushed by wind. Now, what you have to do is try to get pulled by the spiders web, and when you get pulled to the spider you shoot it,and then another spider might pull you right after that. Keep recently doing this
until you get to the mother spider. Hold in L1,and keep on using the powerful attacks. Eventually, you'll beat the spider and you'll have to face Atticus Thorn. One of the ways you can beat him is, to hide behind a wall, charge up your attack,and keep on shooting him. Remember, after every shot,go behind the wall and charge your attack again.
