Packing "more than 26" new songs, Guitar Hero On Tour: Decades takes players on a whirlwind trip across various musical eras with their Nintendo DS Guitar Grip in hand.

"People are asking for songs, and that's what we're giving them," producer David Nathanielsz told Shacknews during a recent interview. "You mention milking the franchise--I don't think we're doing that."

Along with the new tunes, Decades is multiplayer-compatible with the the original On Tour, which arrived during the summer, allowing duels and multiplayer-only song sharing between the two games.
