'Guitar Hero: World Tour' Adds Drums And Music Creation, Challenges 'Rock Band'

Guitar Hero: World TourThe battle for music game supremacy is officially on.

Today, Activision revealed details on the latest installment in their juggernaut franchise, "Guitar Hero: World Tour."

"Guitar Hero: World Tour" adds drums and vocals to the mix. Previously, the "Guitar Hero" series had only centered on the instrument in its title. Feature for feature, it matches almost everything the "Rock Band" experience provides -- and them some.

Activision's peripherals are once again courtesy of Red Octane. "Guitar Hero"'s drums are slightly more complicated than "Rock Band"'s. There are only three drum pads, compared to "Rock Band"'s four, but with the addition of two cymbals. Both sets feature a kick pedal.

The most significant new addition, however, is the implementation of user generated content in the game's "Music Studio" mode. Shareable online via a new service called GHTunes, the press release states Music Studio includes "a full compliment of tools to create digital music from scratch, utilizing all of the instruments."

For music fans, this could be a game changer, but it remains to be seen how complicated the tools are, in addition to attitudes towards copyrighted content.

Additionally, Activision says the Wii version will have in-game dowloadable content. That could just mean user songs, however. We've asked Activision for clarification.

Gamers, are you ready to introduce more plastic instruments into your house? And how does this influence your thoughts on Konami's recently revealed "Rock Revolution"?
