Apparently Halo 4 leaked almost a month in advance. Supposedly someone swiped a few discs off the production line as they were being printed, and on other forums, images, videos are being shown. I won't post any link nor will I discuss it, but this always apparently happens for Microsoft. If it wasn't Halo 4, it was Gears of War 3, and before that Halo:Reach. I'd advise you folks to go "dark" as the vids are already on youtube and people have already livestreamed the entirety of the campaign, including the endings. [Edited on 10.13.2012 8:49 AM PDT]
