Thankfully, there’s a way around that.
Harmonix has introduced “game modifiers” into “Rock Band 2,” which includes such options as a long-needed no fail mode — and a secret song-unlock code.
The catch? You need to know the code! But we’ve already figured that out for you. You simply input the original “Rock Band” unlock code — Red, Yellow, Blue, Red, Red, Blue, Blue, Red, Yellow, Blue — in the game modifier screen.
Once the code is entered, the unlock song modifier will be unlocked. Voila! You have just unlocked all of the songs available in “Rock Band 2.”
