Kojima Productions is working on a new "super confidential project" in addition to Metal Gear Solid 5: Ground Zeroes and Metal Gear Solid 5: The Phantom Pain, Hideo Kojima has revealed.

Announcing the project on Twitter, Kojima posted a photo of three Kojima Productions employees in a meeting room along with the caption: "Kojima Production SUPER CONFIDENTIAL PROJECT's experiment presentation & meeting".

A Metal Gear Solid 4 poster features in the background but the series isn't necessarily related.

So, what could it be? A return of Zone of the Enders? Metal Gear Solid 5 DLC? An all-new IP?

Given Kojima's knack for spilling the beans on Twitter, fingers crossed we find out sooner rather than later.
