According to some leaked images on the Bessatsu Shonen Magazine, Spike Chunsoft is developing a game based on the "Attack on Titan" manga series. The game is currently in development for the 3DS and will be released sometime this year.
At the moment, no details about it's gameplay or genre were revealed, but the Bessatsu Shonen Magazine said that more will be revealed in September on the magazine's next issue. It also revealed that the game's site will be available really soon.
Attack on Titan takes place in a world in which giant humanoid creatures, known as Titans, have appeared on Earth, forcing humanity to live in walled cities. The story centers on three young characters who fight the Titans, seeking revenge after a massive one destroyed their hometown.
