XSEED Games has announced that FuRyu's first-person dungeon-crawler RPG Unchained Blades will be arriving on PlayStation Portable for $29.99 via PlayStation Network on Tuesday, June 26. There's no specific date for the 3DS version of the game other than the always fun "later this year."
As for whether or not Unchained Blades will make an appearance on Vita, that remains to be seen. XSEED says that, at this point, the decision is up to Sony Computer Entertainment America. I'm hopeful it will appear on the store before long, but there might be some waiting involved. (When isn't there?)
If you haven't been following the game, it sounds very promising. As a dragon stripped of his powers, you'll run around on titans, fighting through dungeons with your party and even collecting enemy creatures along the way. The aforementioned price might initially sound steep, but this is promised to provide somewhere in the neighborhood of 60 hours of gameplay.
