We’ve gotten an insider report of a strange new collaboration between Sega and Atlus: Attack on Miku for the Nintendo 3DS.

The game is coming to Japan some time later this year. It’s not directly based on the TV anime, Shingeki no Kyojin, as it’s a spinoff set in the near future, when humanity has started to experiment with genetic augmentation, in an effort to create the greatest weapon.

Promotional art for the game was also revealed:

Quite terrifying.

The experiments resulted in a freak accident, giant sized-Miku, who can manipulate the world through song. Gameplay is described as a mix of music rhythm and total destruction, where you control Miku and wreak havoc upon the helpless citizens via physical attacks and vocaloid songs.

The reveal for the game is coming later today during Nintendo’s latest Nintendo Direct broadcast, where Atlus is reportedly going to reveal something Attack on Titan-related. We’ll keep you guys posted.
