Today at the AOU Amusement Expo, Namco revealed Tekken Unlimited Tag Tournament, an update to the arcade title released last year. This update will probably add various balance changes and other things, but the most notable additions are 1-on-1 battles, handicap battles and four player pair play.

They haven't revealed everything that the update will add, but they do know that it should be finished by Spring. Hopefully, the console version of Tekken Tag Tournament 2 will include all of the content introduced in Unlimited when it hits this Winter. Be sure to hit the break for the new AOU trailer.
