Hyperdimension Neptunia Re;Birth2 was developed based on Hyperdimension Neptunia mk2 for the PlayStation 3 entertainment computer system
Releasing a video, Idea Factory International announced that Hyperdimension Neptunia Re;Birth2: Sisters Generation on PlayStation Vita will be released physically and digitally in both North American and European markets in early 2015. The second installment of the Neptunia Re;Birth series will feature the HDD candidates, Nepgear, Uni, Rom, and Ram. IF and Compa, along with other familiar faces, will return to support the young ones' journey.
The biggest difference between this title and Re;Birth1 is that now you can have 4 members in your battle party.
