WMG: Metal Gear 2: Solid Snake
In Metal Gear Solid
, Campbell states that he and Snake are the only ones who know the real truth of what happened in Zanzibar Land. Couple this with the lack of Big Boss' revelation to Snake
within the game and the original version of the game's use of celebrity portraits for the characters. The reason that Snake looks like Mel Gibson
and Big Boss appears as Sean Connery
amongst others is that they are being portrayed by those actors in universe.
