The 11th volume of the Attack on Titan (Shingeki no Kyojin) manga is set for release in Japan tomorrow, but many Japanese enthusiasts already got their hands on it, and it comes packed with a surprise in the form of the teaser for a 3DS Attack on Titan game.

According to the teaser the game is set for release in 2013, published by Spike Chunsoft. It will be fully unveiled on the October issue of Bessatsu Shonen Magazine, where the comic is serialized.

This comes just a day after the reveal of the browser game Attack on Titan: Wings of Counterattack Online. Looks like this time around we're getting a proper game.
