Forgoing the traditional peripheral-based input, the upcoming downloadable title channels Amplitude and Frequency.
Today, Harmonix officially announced Rock Band Blitz for both Xbox Live Arcade and the PlayStation Network. Rather than utilize the peripheral instruments that have made the series a hit, Blitz requires players only have a controller on the ready to play the beat-match title. Just like Amplitude and Frequency, Rock Band Blitz brings multi-track arcade gameplay that has players switching between instruments on-the-fly to replicate the song.
