This June, FuRyu will publish UnchainBlades ReXX for the PSP and Nintendo 3DS, a first-person dungeon crawler starring a dragon emperor turned human. Today, they released a trailer for the game, which you can check about above.
They also revealed retail goodies with the usual fan-service. For example, Amazon are giving away a postcard set (left), while Animate have hand-drawn phone cards (right). More of these can be found at 4Gamer.
