Hey I was kind of wondering if a Nu player could kind of show me the how to play her online via 360? I'm pretty new I dabbled in GG (meaning I turned it on a couple of times and button mashed my way through as Testament) but I really liked GG and I think BB is pretty awesome so far. I went to the combos and tried a few of them out online but man, that stuff is pretty effin hard and so I dunno, maybe I'm doing em wrong? Just wondering if someone could show me the basics of BB.
