I'm prety sure The Phantom Pain is a Viral video for MGS Ground Zero...The graphics are incredibly similar if you watch both trailers, the MC of Phantom Pain looks A LOT like Big Boss.
Also, Moby Dick Studio's...doesnt actually exist :)
...uhh...ill just put my favorite quote of all time here.
"Welcome to Pain, the second of three...You have dealt the first...now deal with me!!"
