and walk down into it. 

Secret of the Graveyard
At the Graveyard, you have to find the Head's brothers. There will be alot of fake 
heads that are wanna bees. Now,from the begging you'll have a choice to go 
straight or go left. Go left and press square on the one on the left. Ok,now keep on 
going that way, and then you'll find 2 more heads. Choose the one on the left. 
Finally, you'll find three heads on the hill. Stand in front of the heads so that you 
see a backwards triangle. Choose the head in the upper left. If you do this 
correctly, lights will come on, and a huge Castle will come out of the ground.

Ballroom hint
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.

Ballroom gusts
In the ballroom(220 souls needed) when you beat the ghosts go to the front of the 
room and a gust of wind will come you need to the front of the room again so you 
need to let the spiders get you in their web and wait till two spiders have you the 
kill one and then let another one get you when you get to the top you will fight a 
giant spider go as far back as possible then shoot.
