Metal Gear is one of the most recognizable franchises in videogames. The series is still wildly popular after more than 33 years since the launch of the very first title, and out of all the boss fights and various antagonists Hideo Kojima has cooked up over the years, Solid Snake’s confrontation with Psycho Mantis is the most memorable. In fact, many believe it to be one of the best boss fights in videogame history.
