1. The Series' History
MGS has such a long and rich history that Konami released a downloadable encyclopaedia of its characters, affiliations and events to consolidate everything Hideo Kojima has been throwing at fans over the past 25 years. With a continuity and expansive universe to rival that of Star Wars, the movie has a mammoth task on its hands if it is to do the series any justice. From the Philosophers to the Wisemen's Committee to the Patriots and from Zero, Paramedic and The Boss to Sons of The Patriots, there's probably too much history to cover in just one film. My advice: stick to MGS3's story and the tragic betrayal of Naked Snake by his country which sets into motion his transformation into Big Boss.
