I honestly couldn't believe that was Raiden...I actually went back to the part again just to reconfirm it...I mean, c'mon from MGS2 to this? Unbelievable! He is pretty badass and I think it was a good thing that Raiden becomes the "Ninja" for the game. Also, my blood went cold when I saw Snake point the gun to his mouth...I really didn't expect this for some reason...
