Historically, the Guitar Hero and Rock Band games have used a traditional means of progression: a linear list of songs that you complete one at a time, permanently unlocking them for future use. Rock Band 2, however, won't have any such list: to unlock songs, you'll have to play either the game's World Tour mode, or play through the new Tour Challenges, where you play several sets of songs at a time. With the game's release less than two weeks away, it seemed like a good time to take a closer look at the Tour Challenges.
The mode is split up into seven tiers, which roughly correspond to the seven difficulty rankings in the game:
• The Impossible Challenges (Impossible)
• Legendary Act (Nightmare)
• Headliner (Challenging)
• Chart Topper (Moderate)
• Opening Act (Solid)
• Underground Favorite (Apprentice)
• Local Upstart (Warmup)
