Don't really care if anyone belives a word i say i have the data in front of me. So here we go...
Upon browsing the Deception xbox disc i noticed that every playable character has two files like say raiden.ssf and raiden_alt.ssf
I found all the normal characters plus three not in the line up i have now. They are cassius, skab, and just noob. Not noob smoke, just noob.
Now if you belive or not is up to you but i trust the data so only time will tell.
Just gotta figure out how to unlock them.
