DJ Max Portable 2 introduces one more gameplay mode and offers a song selection of more than 60 tunes. In the new Fever Mode, you fill up your Fever ability which, when activated, speeds up the notes and applies a 2x score multiplier. By filling up yet another Fever, you can activate it again for a 3x multiplier, so on and so forth.
