Catherine: Full Body is a remake/enhanced port of the 2011 Catherine video game. Full Body will be developed and published by Atlus' Studio Zero Team for PlayStation 4 and PlayStation Vita.
The reason the developers chose the subtitle Full Body is due to its relation to full-bodied wine. Full Body is Catherine with more content (or depth), like a full-bodied wine. It also sounded more erotic, possibly implying the developers are going to increase the eroticness of the game.
