My search turned up nothing, but disregard if old. :)
Some of you may remember the Modern War Gear Solid series, a bunch of live-action shorts that pit Solid Snake and Modern Warfare's Ghost against the evil ActivistSun and Bobby Kotickovitch. The Master Chief made an appearance during the latter episodes, too, and he's here now, in the finale. Which is pretty awesome, including a nice Red vs Blue reference at the end.
If you've got the time, definitely check the series out. There's some great videogame-related humor in there. :lol
