Looks like the mysterious Kojima Productions project has something to do with the Metal Gear series. Scans from the next issue of Famitsu discuss the project with lots of whited out text. Kojima loves to tease! One thing for sure is the countdown has Big Boss now and will show Raiden later.
Raiden and Big Boss in the same game? Is this Metal Gear Solid: Time Trip? Or Metal Gear Solid: Existence?
