It is beautiful photo-shopping, though.
I've played Gravity Rush and its one of my favorite games 'ever' right now. I've also beaten it. I've also come up with my own moveset for her. I've also done unspeakable things to my Vita but we won't go into that.
She deserves a spot.
Also, as Glidethefirst said:
Well this pic looked fake, simply because it was something that could be reproducable, the other pic, however, seemed completely legit. it would have taken a photoshop master days to do something like the franzea pic properly. that one is the reason why it seems Kat will be appearing in this game.
This is another big reason why Kat might be in the game.
