I got the game yesterday and I managed to unlock Zero today. I'm hopin' to unlock the others over the weekend, but I'm having some trouble beat Yami, and I don't want to be reduced to setting the game to easy mode just to unlock the characters. Part of the problem is when he spams his freakin' health absorbing move which is unblockable in the first form, and then the most damaging move in the third form is a grabbing attack, which can't be blocked and without enough sp, you can't use a Mega Crush to break out of. Any particular regular character that's effective against Yami without having to switch so much?
Frank's kinda odd to use, since most of his attacks are using the funky combination that's hard to register just right. The Onimusha guy's pretty good, I think I've managed to use his rising attack move just right to start an air combo (now I just have to master it then go through with an actual combo ><)
