Cless---Look at the avatar/sig. I wholeheartedly recommend this game. It's tied for my favorite of all time. But to like it, I think you'll have to be fairly open minded. I've never played anything like it before. It's dark, disturbing, depressing---all that good stuff. The voice acting, in my opinion, is also some of the best I've ever heard. I've also got my precious soundtrack---orchestrated techno---I love it.
Thank you for the recommendation kikimm. I purchased the game a few days after reading that and it has been in my Playstation ever since. I have really enjoyed playing it and am currently collecting all the weapons in order to obtain the fifth ending. Since you seem passionate about this game, I was hoping that you could answer some questions for me:

1. Have you got the fifth ending?
2. If you have, without spoiling it for me, could you tell me if it's worth collecting all the weapons for? Would you consider it to be the best ending?
3. What is the name of the song that plays on the second "demo" bit on the title screen and during (I think) the second ending? I really like it.

Overall, I am definitly glad I bought this game. I didn't realise just how "dark" it would be. In particular, I was quite shocked at the bit involving the (SPOILER)child soldiers. It shocked me because it's kind of taboo and I felt strange as my sword was ripping through them as they screamed. But that's alright because I'm a sadist! (joke)
My favourite character was Arioch followed closely by Caim. I really liked Caim because he was a very unconventional protagonist and liked the whole "is he fighting to save lives, or to take them" thing that he had going on. It's a refreshing change to see a main character that can be described as a vengful, bloodthirsty, remorsless, sadistic psycopath!

But even that can't top the sheer lunacy of the mentally ill Arioch! She lusts after children's blood for crying out loud! Does that make me sick that she is my favourite character though?

Goodness, sorry I'm going on a bit but I really think that this game is very good!

sephiroth9006---I beat her with my level in the 30's so your level shouldn't be a concern. It took me a fair number of attempts though. I'm sorry but this is just quite a tough boss! The way to beat her is persistance! Keep trying! Then try again! Then try again! See where this is going?

However, if it's tactical advice you want then that's what you shall recieve. Make good use of R1, L1 and X. In other words strafe and dash. If you perfect that then you should have no problem dodging her standard projectile attacks though the main worry is when she surrounds herself with swords. I sugest saving all your specials for this moment to make life easier.

All in all though, the greatest thing I can tell you is to not give up. From repeated attempts, you will learn how to beat it from experience. Each atempt is not a waste of time if you look at it like this. This is the mindset that I use for bosses that I find tough. You should too.
