In Nintendo’s never ending quest to bolster every part of your mind and body, the company has revealed the next step in its DS-based conquest in the form of Otona No DS - or Adult Face Training.

The title includes a camera that plugs into the Game Boy Advance slot at the base of the Nintendo DS, which videos your face as you play the game. The concept behind the title is what the Japanese call “facening” or facial exercises. By performing certain contortions, you can exercise the muscles under the skin around your skull, making it more taught and appearing younger.

Facening expert Fumiko Inudo lends her ‘facepertice’ to the game, which is co-developed by Fire Emblem makers Intelligent Systems. In the illustration below, the game asks the player to close her right eye while her mouth is scrunched up to the same side. This is probably to give her fuller, rosier cheeks.

Check out the handy little stand boxed in with the software.

What do you guys think? Is Face Training taking Nintendo’s appeal with the DS to non-gamers a little too far, or is it just a natural progression? Can you see yourself performing painful gestures with your forehead, lips and cheeks with your portable in order to retain (or regain) a youthful complexion?

On another note, we wonder how the camera add-on might be used for future projects.

Adult Face Training will be released in Japan on August 2 for 4,800 Yen (about $40 USD), though no release in Western regions has yet been confirmed.
