In addition to costumes from Tales of Vesperia, the upcoming Tales of Symphonia Chronicles HD will also contain Tales of Xillia costumes.
Tale Tale Source reports that Kratos will be able to don a Ludger outfit, while Zalos will be able to put on an Alvin outfit. Meanwhile, Presea will get an Elize costume.
Similar to the Tales of Vesperia costumes, you’ll be able to unlock these optional outfits on your second playthrough of Tales of Symhponia Chronicles. However, if you have a Tales of Xillia save file on your PS3, they’ll be available right away.
