Guitar Hero is set to go all Rock Band, as the mega-popular video game is adding drums and vocals for the upcoming Guitar Hero: World Tour. The game's new guitar will feature a touch pad that allows note sliding, and the ax will larger, nearly replicating the size of an actual guitar. The drum kit is more sophisticated than the existing Rock Band model — the drums are wider in diameter, touch sensitive (so hitting harder produces a louder note) and include dual adjustable cymbals. Van Halen, Linkin Park and the Foo Fighters are among the initial artists that will have playable songs. Plus, players will be able to make their own music tracks (without vocals) by starting with premade bass or drum loops, then using the various instruments to play with tempo, pitch and sustaining notes.
