This week's edition of Japanese magazine Famitsu touched upon a new 3DS project from Capcom that requires everything but your hands!
Translating to Nazo Waku Yakata, the game makes use of the 3DS gyro sensors, microphone and touch features but doesn't require the use of your bone-filled digits. Sound also gets a boost with a 3D sound scheme via headphones or, according to Andriasang your PC (presumably through a hi-fi speaker system through the headphone jack).
Tadahiro Uesugi will pen character designs, Yukinori Kitajima the scenarios and direction by Minoru Nakai.
