In what has become one of the most legendary boss fights in all of video games, Naked Nake’s fight with The End in Metal Gear Solid 3: Snake Eater allowed the player to leave the fight and come back later to discover the “father of sniping” had died of old age.
In another memorable boss fight dating back to the original Metal Gear Solid, Psycho Mantis is able to “read” the player’s mind by reading off the various Konami games present on their memory card. “So you like Castlevania?”
In an amazing penultimate finale in Europe, Liquid Ocelot gathers his forces along a river and demonstrate his control of the AI’s that run the world. In doing so, he simply turned off everybody’s guns, and let them have it.
In an early example of Kojima giving the player many ways to approach a situation, Snake is able to trick a guard into entering his cell by faking an injury and laying over a spilled ketchup packet. So wonderfully dumb.
In one of the biggest (and most wonderfully Kojim) twists in the series, it is revealed that the entirey of MGS2 has been a staged simulation to repeat the actions of MGS1. Part of that freakout is AI Campell slowly deteriorating before your eyes. It’s amazing.
Following the torture sequence meant to mirror Solid Snakes in MGS, Raiden is left with nothing but the skin on his back to escape with. The next 10 minutes of sneaking around guards while Raiden hides his nether regions is something too insane to make up.
Remember that time in Metal Gear Solid 3 when young Ocelot revealed that he summons his ocelot soldiers by literally meowing loudly into the forest? No? You gotta see this.
Vamp, Metal Gear’s resident vampire powered by nanomachines, is nothing if not a walking stereotype, but he’s also pretty awesome. Especially in the several instances between MGS2 and MGS4 in which he gets shot right in the forehead and gets back up. So goofy.
In one of the more genuinely strange Metal Gear Solid moments, the fight with Fat Man is hard not to laugh at. The man is gracefully skating around planting explosives and occasionally shooting at you and it’s just the best. And his eventual exit is also great.
At the end of Snake Eater’s dark middle chapter, Snake plunges hundreds of feet into a river. When he awakes, The Sorrow (a ghost formerly a part of The Boss’ crew/The Boss’ lover/Ocelot’s father) haunts him and must be fought off while avoiding the ghosts of every guard you’ve killed thus far.
In easily the most wholey badass sequence of MGS4, Vamp and Raiden have their final battle while Snake fends off encroaching Metal Gears with a railgun. The twist? Both happen on-screen at once with you controlling the Snake portion. It sounds distracting, but the results are one of the coolest fights in games.
Kojima just couldn’t let go of Metal Gear Solid 4 without the ultimate callback to the first game, a one-on-one, fist-to-cuff brawl between two old brothers that takes a tour through each of the past games via UI and musical references.
The ending to Metal Gear Solid V is great or horrible depending on who you ask, but everyone can agree that it is absolutely insane. The implications of a second Big Boss date all the way back to Metal Gear 1 and 2. The new canon now states that the Big Boss of Metal Gear 1 was not him at all, but instead MGSV’s protagonist, Venom Snake. This mostly explains why “Big Boss” is able to come back in Metal Gear 2, a question that nobody was asking in 1990.
