GROWTH is the third and final Level of BIT.TRIP BEAT. It takes place within CommanderVideo's mental faculties. We witness the construction of his brain, facilitating complex thought. It culminates in the debut of CV's Core, which witnesses the final boss battle. IT has eight Stages, the last one being a boss fight, as usual, and features the music track, "Growth".
In MEGA, the Beats make a sound more akin to modern-bitpop compositions. Possessing a retro sound with modern augmentations, in this case an echo.
