Bandai Namco have confirmed a Japanese launch date for Assassination Classroom: Grand Siege on Kurosensei.
Based on the hit manga (and forthcoming anime series), the game focuses on Class 3-E at Kunugigaoka Junior High School, who are taught the ways of assassination by the mysterious "Kurosensei".
Rather than an Assassin's Creed style game, however, Grand Siege on Kurosensei appears to be more of a 3D fighter. The game also features character creation. You can check out the trailer right here.
Assassination Classroom: Grand Siege on Kurosensei hits Japan on 12th March. The anime series launches on 9th January and will be streamed on Funimation as it airs overseas.
