After making your Rock Band 2 purchase, you may be wondering exactly how you can experience the entire rockin' setlist without having to actually do all the "work". Because, as you're well aware, having to play the game through completion in order to unlock all songs is so 2007.
Thankfully, Harmonix included a "game modifier" option where, with a few presses of the colorful guitar buttons, players can alter the game including a modifier that unlocks the entire setlist. Simply make your way to the RB2 game modifier screen and enter the sequence - Red, Yellow, Blue, Red, Red, Blue, Blue, Red, Yellow, Blue. Tada! Instant setlist unlock! You rebel.
