The last two bosses were pretty damn tough at the end but it was all about Julius for me. On Abbadon, I just whipped him to death and held the whip button down when he summoned the locusts. There's one type of formation though where the come from above, and I did his burning cross attack which RAVAGED the boss' health. Oh the final boss I pretty much did the same thing...whipped him like mad and abused that burning cross attack...did so much damage ;D.
Such a damn good game! First time I've actually gone through the "classic" castlevania style all the way through in a SOTN style title. The CVIII character switching was awesome. I think this is the best 25 bucks I've spent this whole year!
