Following on from light novel series by Reki Kawahara and the anime series – both of which are currently ongoing, Namco Bandai is set to join the fray by releasing a video game based on the franchise, set for release in March 2013.
After a number of smaller trailers, the company has recently unveiled their first proper preview trailer for the game, viewable above. The game is set to be released exclusively for the Playstation Portable, with presumably Playstation Vita support.
