Just a few hours before E3 starts and the new Metal Gear Solid trailer would have been revealed, a Konami member accidentally leaked the trailer. The trailer has since been taken down, but there are still videos up.
This 5 minute trailer starts after the horrific ending of Ground Zeroes and gives us a glimpse at The Phantom Pains story. In the trailers opening scene you can see Big Boss walking through a waste land before transitioning to Boss smearing his face with the ashes of a fallen comrade. Also, throughout the trailer we get a glimpse of a tank battle, a shooting helicopter(Hind-D?), the Diamond Dog soldiers practicing CQC and shooting. We also get cameo’s from Ocelot, Zero and a head scratching scene of Big Boss and Skull Face.
