Kojima Productions are working on a “Super Confidential Project” according to Metal Gear Solid director Hideo Kojima.

Earlier tonight, Kojima teased via Twitter: “An experimental progress presentation and meeting for Kojima Productions’ ‘Super Confidential Project’.”

Kojima attached the photograph above with his tweet, but shared no further details as to what this project is. Judging by the wording, it isn’t related to Metal Gear Solid V or Ground Zeroes, as Kojima tends to tweet rather openly about those games, but one can never be to sure.

Presumably, it isn’t a new Zone of the Enders either, since that project was shelved and the team disbanded. Assuming the tease isn’t connected to Metal Gear Solid V, perhaps it’s another Metal Gear Rising game.
