I love the title of the article, Hideo Kojima's Fox Engine Has Amazing Bra Technology It looks very unfinished, but from the first picture, the only thing I can really say it seems pretty generic. I like the bra detail though, it shows thoroughness, I think.
I'll trust there is more than meets the eye to what we're seeing. Though I am hoping this is Alpha footage, or something like that.
I....honestly have no clue about what to say. It's....average. I'm not very excited, but it is just prototype images.
The reason they show the back is because they have made the bra visible. I think they want to show off the detail/customizability they have put in.
I think prototype means Pre-Alpha. The lack of information makes me think that, at least. Also, it seems like a first person shooter, but I don't think they would go that into detail with customization of characters if it were so. I think it may be an Action Adventure or an RPG, perhaps along the lines of Uncharted?
