Hyperdimension Neptunia Re;Birth2: Sisters Generation is a comedic sci-fi role playing game developed by Felistella for the PlayStation Vita. It is a remake of Hyperdimension Neptunia mk2, with new features and content, and a somewhat different cast.
It was released in Japan on March 20, 2014, and and in the west in January 2015. A PC port was released on Steam on June 2, 2015.
While the main plot of the game remains the same as in the original PS3 game, Re;Birth2's cast of characters is somewhat different. Most notably, core party members Gust and Nisa will not be returning. Instead, several characters from Neptunia Victory, like Broccoli, MarvelousAQL, CyberConnect2 and Tekken have been added. The four NPC oracles will also be playable, and the game features the return of Red - the dating sim obsessed girl based on Red Entertainment from the original Hyperdimension Neptunia game. The game also features one new ending compared to the original release.
