Harmonix has announced the release dates for Rock Band Blitz (or as we like to call it, because it uses a controller rather than instrument peripherals, Frequency 3/Amplitude 2). It arrives on the PlayStation Network on the 28th of August and will retail for $14.99. Blitz will roll onto Xbox Live Arcade on the next day and retail for 1200 Microsoft Points. Rock Band Blitz is apparently compatible with thousands of songs in the Rock Band Music store and all of Blitz’s songs will work with Rock Band 3, which is promising if you are a fan of the Rock Band franchise (and Amplitude). Read on for a trailer and a list of all tracks announced so far.Read More
