Konami showed two MGS4 "trailers" at TGS. One was the real MGS4 trailer and the other was a sequel to the E3 MGS4 teaser. Titled Metal Gear Raiden: Snake Eraser, it shows Raiden once again trying to snatch the main character role from Solid Snake. The trailer is not available for download, but it will be included as a bonus material in MGS3: Subsistence.
