Meta Gear creator Hideo Kojima has explained the decision to hand-off development duties of Metal Gear Rising to Bayonetta dev Platinum Games.
Responding to queries from fans on Twitter (via Andriasang), Kojima said the original development team ran into trouble narrowing down what the core of the game should be.
Believing the project would not get completed, Kojima secretly cancelled it. At this point the Kojima team had already fleshed out many areas of the game such as story and motion capture work, and eventually Bayonetta and Vanquish developer Platinum expressed its passion for the project and offered its services in reinventing and completing Rising.
The game's title was changed to Metal Gear Rising: Revengeance to reflect that it isn't part of the main Metal Gear Solid seris, but is instead a spinoff that takes place after Metal Gear Solid 4.
"We've only said that the period setting is several years after MGS4. Metal Gear Rising is not part of the Metal Gear Solid series. At present, we can't say more than this," Kojima posted on Twitter.
Kojima has also confirmed Rising will run at 60 frames per second, a requirement he personally requested..
"I made one request of Platinum: a cool Raiden who moves nice and smooth at 60 frames per second."
"The old Rising that was being prototyped at Kojima Productions looked visually like Metal Gear, but it was 30 frames per second and required complicated controls."
Over the weekend Bayonetta, Devil May Cry and Okami director Hideki Kamiya also said on Twitter that he's not involved in the project.
"Hey everyone, I said 100000000000000000000000000000000000000000000000000000000000000 times that I have nothing to do with Metal Gear Rising."
The VGA Metal Gear Rising trailer leaked all over the internet before its official reveal at the event.
