Apparently you should get a Kasumi and/or Ayane gamerpic upon first bootup. I haven't played the game myself though and am referring to the unlockable gamer pics concept page for confirmation. Google around a bit more and I'm sure you'll find your answer to this.
yeah i been trying to look it up but i think the only way to get it is to have one of the OG white Xbox like what @Demoskinos said. ): man i bought this game for no reason?
Yeah I've got gamerpics of Ayane, Kasumi, Tina and Lei Fang that were on my HDD when I purchased my launch 360 along with some other themes and gamer pics that you can't really get anywhere else except if you had a launch window 360.
