Unchained Blades is due for the 3DS in December, "hopefully," XSEED writes on its Facebook page. After that launch, XSEED might start localizing the sequel, Unchained Blades EXXIV, for western audiences.
"We're still struggling to get the original out on 3DS first," XSEED writes. "After that's finally out the door (hopefully December), then maybe we can start thinking about the sequel."
Unchained Blades hit PSP on June 26, for $30, and it is available now on the Vita via the PlayStation Store.
