The meaning behind Konami's "Piece Walker" teaser from last month was revealed today. And it's not a portal, nor a demo or a new project. It's just some jigsaw puzzle.
Well, the puzzle hasn't launched just yet, but that's what it'll be, likely a Flash game. It gets going at 3pm Thursday (Japan time, which is 5pm AEDT). There seems to be some sort of head-to-head component to the puzzle too, like a race to solve it first.
