The wraparound jacket band and insert included with the 11th volume of Hajime Isayama's Attack on Titan manga is announcing this week that a Nintendo 3DS game has been green-lit for this year. Spike Chunsoft is developing the game. More details will be in the October issue of Kodansha's Bessatsu Shōnen Magazine on September 9. Strategy & Partners is developing a separate browser game for personal computers, and it already launched a social game, Shingeki no Kyojin -Hangeki no Tsubasa- (Attack on Titan: The Wings of Counterattack), on the GREE mobile platform. The manga's official Twitter account had revealed in April that a console or portable video game was planned, and producer George Wada had said that it was planned for next year.
