Atlus is brave.
The love triangle is going to become a love square, as the previous game (which launched on PlayStation 3 and Xbox 360) had Vincent decide between Catherine and Katherine. However, Full Body introduces a third character (called Rin… who is a trap, let’s put it bluntly) into the mix. You can see the new addition in the trailer.
The puzzle platformer will launch in Japan in roughly a year (next winter) on PlayStation 4 and PlayStation Vita. We wouldn’t be surprised if the localized version (confirmed by the website) would skip the six-year-old Sony handheld. It has no release window yet. We would put it around early 2019 or so.
So if you skipped the original release in 2011 (or 2012 if you are from Europe…), you could now catch up. We also embedded a video from the original game to help you understand how the gameplay works – the trailer barely focuses on that aspect.
