Frank Jaeger, Gray Fox, being Naomi's adoptive brother may seem to come out of nowhere, but there are hints. Firstly there's her extensive knowledge of how he was cyberized, and look at her last name, "Hunter." "Jaeger" is German for "Hunter."
This technically only applies to The Twin Snakes, although this was also mentioned in the Japanese script for Metal Gear Solid, as well. Anyways, Psycho Mantis's line of "It feels so... nostalgic" in regards to performing a good deed for Solid Snake and Meryl Silverburgh before dying seemed very confusing to some fans... until you remember that Psycho Mantis's mother died while giving birth to him, which meant he was referring to what his mother did for him before dying.
Not to be bursting bubbles, but the line "It feels so... nostalgic" was actually in the Japanese version of the original game, and it refers to something from Metal Gear 2: Solid Snake. The line was changed to "kinda... nice." for the US localization because that game never was released here.
Actually, Hideo Kojima stated in the director's commentary for Metal Gear Solid that Mantis's line was actually in reference to his mother's last moments being used to give birth to him. Read it here: http://muni_shinobu.webs.com/mgs/commentary2.html
I know that it isn't the real reason, but the "feels good" and the "nostalgic feeling" set off a different bell for me. See Mantis constantly breaks the fourth wall, right? Well, what's stopping him from doing that while dying? To me, Mantis felt nostalgic in Twin Snakes because he already had done a good deed before: In the Playstation version.
Also, it seems odd that it required a bribe to persuade Donald Anderson to build Metal Gear REX, especially when he believed in nuclear deterrence and would have allowed for it to be built anyways even without the bribe. However, when you remember that he was Sigint, and that he had a nightmare referring to Metal Gear, it suddenly makes a whole lot more sense as to why he'd have to be bribed.
Well, actually, there are plenty of reasons he could have been bribed. It could be that they didn't have to bribe him, but he took it because they were offering (ie. simple greed). Or maybe the bribe wasn't about Metal Gear specifically but about allowing ARMS Tech to be the company who built it, or to ignore their financial troubles. That is assuming he was bribed at all- bribes were definitely going around, but that does not mean that he was one of the people collecting them. For all we know, the whole thing was Anderson's idea in the first place.
At one point, Revolver Ocelot mentions being impressed by Snake's skills, and says something to the effect of "Just what I'd expect from someone with the same code name as the boss." The first time you play the game, it's obvious that "the boss" refers to Liquid Snake, who Ocelot was working for at the time. Then comes Metal Gear Solid 3, where we learn that Big Boss (who Solid Snake is cloned from) once went by the codename "Naked Snake"... and that Ocelot knew him during this time. Maybe it was intentional, maybe not.
It probably refers to Liquid Snake. Whenever Mantis or Raven refer to Liquid, they usually call him "boss". At best it would be a double meaning, because both Liquid and Solid have the same code name as Big Boss, and both were cloned from him.
Not to mention the sheer, and utter mixture of Hilarity and Horror that the entire Shadow Moses Incident can be caused by someone having a major jealousy-inducedtemper tantrum taken up to eleven, hilarious because the motive was because Liquid didn't like being the "inferior" brother, and horrifying because of just how easily someone that unstable can take over a nuclear disposal site and hijack a Metal Gear - Shini
Ocelot's hidden conversation at the end implies this was all part of the plan. Sprangitudinous
This not-troper always liked the MGS games, even with the long and wordy cutscenes, but always felt that some elements were a bit... off. Then he realized that MGS is a Deconstruction, not just of movie and video game tropes, but of the entire medium of video games. Everything from the fourth wall-breaking Codec calls to the perfectly straight tutorials to Psycho Mantis' mind reading and psychokinesis to GW urging Raiden to turn off the console is part of an attempt to show what games can get away with in the name of fun, without banging the players head with it or turning into a total parody. And the way the endings for each entry in the series got steadily more depressing was an incredible setup to the amazingly heroic finale of MGS 4. —Not a troper, but I use the screenname "Bad Username" frequently.
MGS 2 gets even more mind screwy when you consider not only the actual plot being a deconstruction but also an allegory to the player-character relationship. The Patriots plotted perfectly to get Raiden to do what they wanted him to. Even though you're trying to help Raiden, you're controlling to make the plot fit while looking at him from a 3rd person view. Guess what that means? I must fight The Patriots! No player, you ARE The Patriots.
I see it as the opposite. In MGS3, The Boss' tragedy, and indeed a recurring theme throughout the series, is the Patriots manipulating soldiers to do what they want them to do. Just like the player is 'manipulated' into doing what the game wants you to do. Similarly, the trend of the player-character being mocked for blindly following orders can be seen as a Take That to the player doing whatever the game tells them to do.
In Metal Gear Solid, Snake talked about how virtual training is no substitute for real life experiences. At first, I thought it was just him talking about how he had actual battlefield experience, making him more skilled. Then I realized: what is the definition of a Video Game? This line is basically Hideo Kojima saying that just because you can do surgery or practice law in video games doesn't mean you can do it in real life. The game is basically telling us to not play it too much.
After playing MGS 1-3, and reading the comics for 1 & 2, I read this page, lo and behold the light shines brightly. What the troper above mentions about Liquid's tantrum, makes it weirdly plausible that Solidus anticipated that the two most dangerous individuals to his plans were unlikely to be easily eliminated-unless the killer was one of the brothers. Given that Liquid and Solid are on a whole new level compared to any other soldier alive at the time, it makes sense for Solidus to set them up to kill each other. The only way he could pull this was to isolate them from society, place them in a perceived high stakes situation, wait for a body, and nuke an already irradiated island, safely in the knowledge that he could blame the detonation on terrorists mishandling the warheads. It further makes more sense when we examine the presence of a Metal Gear, its the only prize big enough to get Liquid there, and scarier enough for Solid to come out of retirement. The sheer size of Rex makes covert transport from such an isolated area, quite difficult, and despite the complexity only the plans are necessary for Solidus to build a Rex in new location. Nuking the island destroys any records of Rex. Kills the CEO and DARPA representatives who knew about Rex. Removes the Next Generation Special Forces who were slowly coming apart genetically(covering up that little not so legal experiment), wipes out Fox Hound which seems to be a pointless liability given its tendency to do The Starscream to the US GovernmentUnited Nations unlucky bastards stuck with telling them what to do. Foxdie is the chancy bit however, as Solidus's ace in the hole required someone he did not have complete control over to seek vengeance at a jeopardise-the-entire-mission level. Ocelot's selling of the plans is just his Chronic Backstabbing Disorder, something Solidus could not stop (and probably anticipated) as he needed Ocelot to rig this Gambit Roulette, hence why Ocelot does not show signs of Foxdie (Haven't played MGS 4 but if he does turn out have Foxdie then it kind of changes Ocelot into Snake Plisskin from the second movie...). I nearly wrote off my computer with a glass of coke when this clicked ;)- Eyclonus** And the phrase "code". It refers to both codename, and genetic code. - pinkdalek
A bit of fridge creepiness. Before the the Psycho Mantis fight in MGS, there are a couple of unsettling details. 1. The door at the end is closed. 2. Once Meryl becomes possessed, you notice that the first person view is.. third person - through a mask of sorts. That leads me to conclude that Psycho mantis is in that hallway, stalking you. It also points it out as when you enter the commander's room, the door waits for a second (perhaps someone's in the doorway?) until he comes inside. Creepy.
That's exactly what's happening, yeah. The 'third person' view you mentioned is Mantis's view, which is exactly what happens if you use first person during the boss fight.
