The First 15 Minutes of Hatsune Miku: Project Diva F 2nd (Vita)

Copied from MobyGames:Hatsune Miku: Project DIVA F 2nd is the sequel to Project DIVA F, featuring many of the same gameplay elements with a few additions, including sliding notes and double scratch notes (done on the Vita's touch screen and the PlayStation 3 controller's analog sticks). The majority of the songs in F 2nd are returning from previous entries in the series, though there is a number of new songs with original videos.
