The brand new Guitar Hero is set to come out July 17th
So y I here you ask is this in the Handheld's section??
That is because it is the Very first Guitar Hero to be made for the DS
Vicarious Visions have said that they have been planning a DS Guitar Hero since early 2007 even though it wasn't actually announced until 7th September 2007
Guitar Hero On Tour's interface consists of a little Guitar hero button cartridge to be inserted into the GBA slot on the DS. As having all five Buttons (Green, Red, Yellow, Blue & Orange) would be a bit cramped they decided to opt for the easier option of removing the Orange button for this game. To strum instead of flicking a little Strum Bar you get a special stylus shaped like a pic to use on the touch screen. To use Star Power you shout into the Mic & they have added new battle power ups for the Guitar Battles including making your Guitar go on fire & Having to blow into the Stylus to put it out so you can play.
