There is no TU yet as far as I know and I'm playing the game everyday on retail live and RGH, for future reference you can get all your TU's from the below links http://www.xbuc.net/ http://marketplace.jqe360.com/
I don't think there is still an update. Game seems real buggy to me. The X and Y keeps stop working within is kind of a problem since you can't fight then. JR
