Peacewalker, and the anime-mech-loving geek inside us has read hints that it could be none other than Zone of the Enders 3.
Kojima made several tweets over the weekend regarding work on his "next title", but as far as clues go there was really only one:
“The project plan still hasn’t reached a detailed level, but everything is advancing simultaneously in my head.
“Title, game design, story, characters, setting research, the mecha that appear, casting, graphic direction, sound, beginning and ending, the major story sequences. It comes together naturally in my head.”
Yeah, we know... we're writing a story based on 'mecha'. But how many other Kojima games do you know that have mecha in them? Besides, the gaming guru has already gone on record to say that Z.O.E. 3 was on the top of his list, so it's not a complete stretch.
Can't wait, if true.
