We’ve known about Guitar Hero: On Tour for a while now, but until today, we had no clue how the popular series could possibly translate to the Nintendo DS. Apparently, the game comes with a peripheral that attaches to the DS, which you hold Brain Age-style. You strum the touch screen while pressing the buttons on the peripheral.

It appears that the game will only have four color-coded buttons rather than the standard five, but whather that means the game will actually be easier remains to be seen.

No songs have been officially announced for the game yet, but there is an OK Go song playing during the teaser video, which you can view below.
