I'll definitely be first to admit that I'm skeptical with Nexon, Ghost in the Shell is a tricky IP and I'm not quite sure Nexon will find the talent to do the series justice. With the half-assed F2P FPS Combat Arms it's hard to imagine this turning out well, but I'll hold my judgements. The game has been described to emphasize heavily on hacking and will allow players to customize their body, talk about vague.
Other than the fantastic concept art released, all we know is the game is set for an early 2014 release for Japan which means we'll most likely see this title localized never. For a few more pieces from the games announcement hit the jump, the art is definitely fantastic.
