Publisher Activision has issued five new screenshots of Guitar Hero: On Tour, further illustrating what Guitar Hero looks like when it's running on a Nintendo DS.

Among the shots are glimpses of the game's local wireless multiplayer and its use of the DS' microphone to blow out on-stage fires.

According to GameSpot, the game will feature over 25 tracks, including OK Go's "Do What You Want," Blink 182's "All the Small Things," No Doubt's "Spiderwebs," Jet's "Are You Gonna Be My Girl," Twisted Sister's "We're Not Gonna Take It," and an unknown Nirvana song.

Developed by Vicarious Visions and utilizing a special guitar grip add-on that plugs into the DS' Game Boy Advance cartridge slot, Guitar Hero: On Tour is expected to arrive this summer.

Following up on yesterday's announcement, publisher Activision has issued two teeny-tiny screenshots of the first Guitar Hero entry on the Nintendo DS, along with a piece of character art and clearer images of the guitar grip controller. Developed by Vicarious Visions, Guitar Hero: On Tour utilizes a special guitar grip that plugs into the DS's Game Boy Advance cartridge slot, with players strumming via the touch screen and a pick-shaped stylus.

Guitar Hero: On Tour is expected to release this summer. No price point has been announced for the game, which will feature tracks from Nirvana, OK Go, and No Doubt.

Activision has revealed the long-rumored DS rendition of its Guitar Hero franchise and its accompanying peripheral, IGN reports.

Entitled Guitar Hero: On Tour, the game utilizes a peripheral called the Guitar Grip to recreate the Guitar Hero experience. The peripheral plugs into the Nintendo DS's Game Boy Advance slot on the bottom of the system and features four buttons versus the traditional guitar controller's five.

With the peripheral in place, the DS is held in a book-style orientation in which the touch screen is used to strum. The Guitar Grip also features a strap to secure the peripheral and system to gamers' sweaty mitts.

Guitar Hero: On Tour will feature more than 20 licensed songs from bands such as Nirvana, OK Go, and No Doubt, along with the usual slew of unlockable guitarists and other bonuses that gamers expect from the series. The game is developed by Vicarious Visions, and is scheduled for release this summer.

The announcement confirms Guitar Hero: On Tour as one of two Guitar Hero titles revealed by Activision to be due out before the summer, the other being the recently announced Guitar Hero: Aerosmith. A third Guitar Hero title, which is rumored to be Guitar Hero IV, is scheduled for release in the fall.
