Guitar Hero is making it’s way to the handheld market, with Guitar Hero On Tour. Instead of using a full on plastic guitar, a more DS friendly fret board attachment plugs into the GBA Expansion slot. You use a guitar pick stylus to strum on the touch screen.
The game is set to feature over 20 songs (80% of which will be master tracks). The game is set to come out this Summer, but no price was announced.
