A tweet by Hideo Kojima appears to have confirmed the rumors that he is indeed the man behind the mysterious The Phantom Pain.

Earlier today Kojima tweeted a picture showing a video editing suite which features a still from the end of a recently cut trailer with the file name “TPP_GDC 2013_720p_esrb.” The ESRB is the U.S. rating board, for those wondering. The most interesting part is the TPP which can only stand for The Phantom Pain, and the fact that it clearly lists Kojima as Producer, Game Designer, and Director.

The trailer in the image is apparently due to be shown during Kojima’s GDC presentation that was recently extended from 60 to 90 minutes in length. The session is titled “Photorealism through the eyes of a ‘Fox’ – The core of Metal Gear Solid: Ground Zeroes.”

This could easily be just a new Ground Zeroes trailer, but why use the initials TPP? Is Kojima just trying to mess with our heads or is he trying to confirm what we all already assume to be true–that he is indeed the man behind this mysterious project?
