The Metal Gear series is famous for its inventive boss battles, from Psycho Mantis’ memory card reading in the original Metal Gear Solid to discerning Laughing Octopus’ disguises in Metal Gear Solid 4 among others. Some could even be quite difficult, like taking care of the Harrier jet in Metal Gear Solid 2 or taking care of The End in Metal Gear Solid 3.
