Guitar Hero World Tour Mobile: Rock While You Commute

Vocals aren't practical for the mobile version--which still rocks, by the way--but a drum track is. Activision and game-maker Hands-On Mobile have introduced a drum choice for every song.

There's a lot more news here--the updated game, which has a new look and two fresh game-playing features (can you say "battle mode"?). There are also technical details that could make a difference to how the game looks and sounds on your individual phone. Finally, there's all the practical stuff about when your carrier will stock the game and how much it'll cost you. Let's take one at a time.

Also new to the mobile game is the multiplayer battle mode, where Hands-On Mobile has created a good way to pair you up with similar players all over the world.
