Well, that was quick. Just hours after Arc System Works released the Version 1.03 update patch for BlazBlue: Continuum Shift in Japan, Aksys have the U.S. version ready to go, too.
The U.S. Version 1.03 patch — including the Platinum the Trinity DLC character — for Continuum Shift is now up on Xbox Live. This patch updates the game to the current version of Continuum Shift II. You can view a more in-depth list of changes the patch makes here.
