WTF with this tower thing man... Some of these missions are very tough... The current one is killing me. I am allowed to select one character. I must defeat 11 people in a row... The hard part is they can not be knocked out the ring, they can not be thrown and they each have the freaking auto deflect crap on... My god...
Sounds like they want the player to use some kind of reversal or critical attack move. I recommend sucking back the frustration and train on the hardest level, then do the challenge on the hardest level, then when you feel you've improved, soften up the level again. This can take days but in the end it'll be worth it.
After unlocking everything in Soul Calibur games, All i do is play it in free training mode on Ultra Hard when I haven't anyone to play against.
I hope I can get a copy tomorrow I wish I can play now.
