sorry but i'm going to ruin it for you, basically, in the end, snake reveals that darth vader was in fact his father (not big boss) and his real name is darth snake, meryl actually turns out to be a man, raiden is actually gay and takes it up the bum and enjoys it, big mama was a 34DD, the patriots were in fact massimo moratti, zlatan, james bond, tony blair, molinaro, bumble bee man from the simpsons and batman (it was all a setup) and liquid ocelot was just 'pretending'

to be liquid all along.....................
