Hands-On Mobile is following up its bestselling "Guitar Hero: Mobile" and "Guitar Hero: Backstage Pass" mobile games with a mobile version of the upcoming "Guitar Hero World Tour."

While the console version of the new game comes out over the holidays, the mobile version won't be available until the new year.

However, Hands-On says the game will allow players to compete against other mobile users from other operators, download new music, and add drums as a playable "instrument" for the first time.
