Amplitude has a fairly open structure as far as which portions of the game can be played at what time. For the most part this section will simply explain the requirements for unlocking the songs at various difficulty levels.
Boss songs are unlocked by completing each of the previous songs in the arena. Bonus songs are unlocked by achieving a minimum number of points on the previous songs in the arena.
Boss songs and Bonus songs unlock new Freq Prefabs and new parts for custom Freqs.
Please note that the content below may contain spoilers for some people. The Artist and Song names are hidden behind spoiler tags for Boss and Bonus songs, but the rewards for completing these stages are not. If this is something you don't wish to read, you may want to skip these stages.
