If you missed it the first time around and are having difficulty locating a physical copy, we got good news.
Today, NIS America has announced that Hyperdimension Neptunia Mk2 will become available as a digital title on the PlayStation Network on August 7 in North America and a day later in Europe. …yeah, long name.
The cool part is that the PSN version will be "fully compatible with preexisting trophy and save data," so you could go back and forth between physical and digital versions if you needed to (for some reason). This sequel focuses on the young sisters of the four heroines from the first title; they're out to take down the Criminal of the Free World, Arfoire, who has defeated the four CPUs of Gamindustri. …okay, it's a bizarre plot but that should intrigue you, right?
Anyway, apologies on not getting the review done earlier. Things were a little hectic at the time; I'll try to review it when it hits the PSN.
