Guitar Hero is already one of the biggest games ever on home consoles, but can it really be made to work on a portable like the DS? A lot of effort has certainly gone into ensuring it does, with the Guitar Hero - On Tour coming bundled with a special Guitar Grip attachment of four plastic fret buttons. There might be only four fret buttons, but the game can be as hard as ever Blow into the microphone to put out a fire during an axe battle Guitar Duels work a lot better than the boss battles in Guitar Hero III

With the Guitar Grip in place, you hold the game horizontally and watch as the notes you have to play scroll down on the top screen. You then have to press the appropriate fret buttons and strum along on the touchscreen with the included plectrum shaped stylus.

Its a clever way to get around the fact that theres no actual guitar controller, but watch how long you play, or you may get a case of hand cramp. You'll also want a set of headphones for maximum sound quality. No, Guitar Hero - On Tour isn't quite the same as jamming in your living room with a full guitar controller. But for the Guitar Hero-fan on the move though, this is as good as it gets.

Key Features
