Banpresto must be the king of this with its Super Robot Wars multiverse, where things will be foreshadowed that usually don't even happen in the same universe. The big one of which is the Axel Almer and Kyosuke Nanbu rivalry, which was foreshadowed before either of them even appeared. "Throwaway" lines across three games where neither actually met each other (or, in one case, showed up at all) ended up being a game-long theme of Original Generation 2.
Another version happens in Original Generation 2. Ryusei mentions substitute names for his Humongous Mecha, and comes up with DaiRaiOh, partially naming it after one of his teammates. Another character mentions that the name may already be taken. Sure enough, in Alpha 3 (an Alternate Universe), a Super Robot named RaiOh is introduced, and later gets rebuilt/upgraded to DaiRaiOh.
Which then comes back in Original Generation Gaiden, when the guy who ends up piloting DaiRaiOh makes an Early-Bird Cameo.
Axel takes this even further in Original Generation Gaiden. He mentions a predecessor of Lamia, W-07, which is said to have some exclusive devices installed in only Lamia and W-07. Surely enough, later on, Banpresto worked on a spin-off game and introduced Aschen Brodel, a somewhat regular Lamia Expy... only to later (recently) reveal that she is W-07.
Another far more direct version in the same game, which featured missions that made up the prologue of Super Robot Wars MX. A more humorous version when MX's female protagonist makes a cameo of her own, and remarks that she would never wear an outfit as Stripperiffic as Lamia's... of course, the outfit she wears in MX is even more so.
In Third Super Robot Wars Z: Jigoku Hen, Shikuu's Leitmotif has hidden lyrics based on possible events in Tengoku-Hen. spoiler alert He who bares the spheres He who will become the King Praise to him, Praise to him He will return the ends of times are near He who bares the spheres The 12 chosen their cruel fates will meet They will meet again, all the spheres He who bares the spheres He who will become the King He will free the universe
Naomi Hunter's surname is a huge clue to her relationship with a certain Frank Jaeger: "Jaeger" is German for Hunter and Naomi is Frank's adoptive sister.
This plot twist is also used in Metal Gear 2: Solid Snake when Gustava Heffner talks about her old lover "Frank Hunter". However, the manual spoils this twist by mentioning that her lover's name is "Frank Jaeger".
If you try and contact Master Miller when fighting Liquid in the Hind-D, you will get no response.
Ghost Trick has no end of hints leading to the ending, when you find out the character you've been playing as is actually a cat.
The main one being that Sissel can't read!
Also, he's decidedly mean to rats and likes cramped dark places.
The Ace Attorney games have a lot of this, particularly Trials and Tribulations and the bonus case 'Rise from the Ashes' in the first game, which was created as part of an Updated Re-release with the writers knowing what was going to happen in later games, leading to lines foreshadowing Trials and Tribulations ("We certainly can't get a dead person to testify") and Apollo Justice (when Phoenix shows Lana his attorney's badge, her response is something along the lines of "The paint's flaking off. Give it three more years, then we'll see the real you." Three years later, between Trials and Tribulations and Apollo Justice, Phoenix is disbarred. The last one is subtle because many characters make comments on the badge aging.
In 1-5, you can inspect a pile of items in the evidence room. Gumshoe will point out an electronics detector, saying it might become useful someday. This gets used in Justice For All when you try and find the spy camera and mic that Matt Engarde used.
Also in the second case of Trials and Tribulations, when talking about Mask DeMasque Phoenix says that when you're famous there are always imitators. Pearl then says that if Phoenix works hard, someday he'll have his own imitators. The next case revolves around Furio Tigre impersonating Phoenix to cover a crime.
Even further the three cases that Phoenix handles during the game (2,3,5) all have a duplicate theme which is echoed slightly by alliteration in the subtitle (T & T) and parallel meanings of the words. In case five, Dahlia acts as an imposter Iris.
Lana's line is quite subtle, as the paint on his badge is something a quite a few NPCs mention; the time it will finish is not.
Investigations has an odd case of reverse-foreshadowing. Specifically case four. It's a flashback to four years before the first game and six months before Edgeworth's first trial, and contains multiple references to future events. If you hadn't played the first few games you wouldn't get the meaning behind von Karma's comments (he killed Edgeworth's father), the fire extinguisher being used in a crime (later used to bash Phoenix on the head and give him temporary amnesia), or Edgeworth mentioning his badge won't stay shiny forever (his reputation will eventually be tarnished).
A comment from Manfred von Karma is that case is actually both reverse-foreshadowing and genuine foreshadowing. von Karma mentions that there are some people who are above the law. Initially the reader assumes that he's referring to himself, and his crime of killing Edgeworth's father. However, in the next case, Edgeworth faces off against a criminal that has diplomatic immunity, making him "above the law".
In case five, the 'shadow of the Yatagarasu' is formed by more than one statue. This foreshadows the fact that the real Yatagarasu is more than one person.
Since we've already mentioned Rise from the Ashes, it's also worth noting a line from Gant, later in that trial, which may allude to Apollo Justice:
Gant: Defense attorneys can forge evidence too, isn't that right, Wrighto?
And again in the second case of the first game, Gumshoe remarks that the possibility of the victim writing the killer's name before death happens all the time. All the time as in once per game, twice in the first game.
Nine Hours, Nine Persons, Nine Doors: On certain routes, the team finds a bracelet with the number zero. Upon experimentation, they discover it actually represents the number six, foreshadowing the fact that Zero is actually June.
What looks like a "0" on the bracelet is actually the letter "O", whose digital root is 6. This is also a hint about another letter that looks a lot like a number...
There's foreshadowing all over the place; one particularly subtle bit is in a Panty Shot gag of all things.
When the group is looking for Snake, Junpei can talk to Ace, and remark that he's surprised that Clover and Snake are siblings. Ace asks why, and when Junpei replies it's because they look so different, Ace says he supposes so. Ace has prosopagnosia; he had no idea they looked different.
Not too important at first, but when you look at the lights in the 1st Class Cabin, Snake looks surprised until Junpei clarifies where they are. Light is Snake's real name.
In a bit of genius, during the safe ending you end up with the password 14383421, according to an interview with the director, he chose that number because if you multiply it by nine you get 129450789...
The detonators not being real,except for the one in the ninth man, and possibly the one in Ace, is hinted at in a couple of places, specifically when Junpei observes that one of the searches for the DEAD felt like a lot longer than 81 seconds.
In one of the puzzle, Seven will remark that water (H20) is made out of 2 hot orphans. Indeed, there are two orphans in this game. They are Akane and Aoi (Santa's real name) and they are siblings.
Like its predecessor, Virtue's Last Reward has a massive amount of foreshadowing hidden in easily-missed places. To start, look at the cover artwork on the game box - specifically, Sigma's weirdly gray hair and glowing right eye.
In Phantom Brave, Marona fantasizes Scarlet the Brave as a strong, masculine hero. Ash dismisses it with "Scarlet is a girl's name," and imagines him as effeminate. Scarlet turns out to actually be female.
One of the unlockables in Mega Man ZX Advent is a 1-level NES-style remake of the game. Shortly thereafter, Mega Man 9 came out.
In the ending of Mega Man X 4, the title character is asking Zero that if he (X) goes Maverick, then Zero must "take care of him". This actually foreshadows two events, although the circumstances have been twisted by the time they occured:
1) In X5, wherein their destined battle finally happens, although here it was X who thinks Zero has gone Maverick (or, in the non-canon path, Zero actually is).
2) And in the first Mega Man Zero game, it wasn't the real X that was a Maverick and who Zero must destroy, but actually a clone.
Another way to look at X's situation in X4 would be The reason why Copy X was created. X used his body to seal the Dark Elf following the Elf Wars. The first game hints at a nervous breakdown from the trauma of the fighting. Though never confirmed, it does explain why X never inhabited a new body since the Zero series confirms that his or Zero's body can be perfectly copied. Whatever the reason, since X abandoned his post without preparing someone to take over, humanity scrambled for a leader and put the unstable Copy X in charge. All the death and destruction that followed is partly X's fault, so he did become a Maverick.
Another subtle one from Megaman X5: part of the opening music and start menu theme is actually Zero's death theme from Megaman X. Guess what happens at the end of the game...
After you get the star force in Mega Man Star Force 1, there are two separate events that foreshadow the event of Luna Platz finding out that Geo Stelar and Mega Man Geo-Omega are the same person:
First when the kids do the class play that Luna came up with, Pat Sprigs Gemini Spark is absent, so she asks Geo to fill in and when he puts on the suit she imagines that she is seeing him in wave form.
Later when they get attacked by a jammer, he puts her in a classroom and orders her to stay there, and as he is leaving to take care of it she thinks that he is talking in Mega Man's voice, and of course he is as they are the same person.
Chop Chop's cryptic lyrics in the first song on Um Jammer Lammy ("Pick burnin' cry fly, chop choke!") actually foretell events that will happen in later stages.
The Chrono Cross opening have the camera zoom in to Kid's pupil, transitioning to the burning orphanage FMV.
The guy Aeris famously describes as "are sick" very early on in Final Fantasy VII has a mysterious tattoo, the meaning of which (as well as the meaning of his illness) will not be revealed for quite some time. This is the only hint of its kind during the game's first half that something much bigger than the conflict with Shinra is going on.
Final Fantasy IX, halfway through the game when the heroes meet the villain Kuja for the second time, he responds to Zidane's inquiries about his plots with the line "Oh, brother... But you're not ready yet!" On the first playthrough this just seems like uncharacterically crude choice of words from him (he speaks like he's in a Shakespearean play most of the time). After you play the game again, knowing that he and Zidane are brothers, the line seems like such an obvious hint.
Final Fantasy X has a shot of the penultimate boss, and the stage in which you fight him, within the first twenty minutes of the game.
The first half of the game is absolutely blatant about foreshadowing the fact that Yuna will have to sacrifice herself to stop Sin. It's hard to count the number of times Tidus suggests they come back to a place or do something after they beat Sin, and Yuna just looks sad.
Auron being an unsent is also foreshadowed a lot. He refuses to go into the Farplane, for one, and once the party returns and Yuna is forced to send Jyscal, he collapses and starts leaking pyreflies.
Final Fantasy X-2: After Yuna has a nightmare about herself and Tidus being killed by a firing squad at the start of Chapter 2, Rikku offhandedly tells Yuna to "Blame it on your new jammies!" (the Songstress Dressphere). Turns out a while later that this has real plot relevance: the Songstress Sphere was channeling Lenne's memories (and partially her appearance); hers and Shuyin's traumatic death was the fuel for the nightmare, and the main conflict in the game.
Grim Fandangoloves this. A lot of the dialogue, most of it optional, hints at what's going to happen as the game progresses, and the solutions to certain puzzles are foreshadowed early on.
Manny: I wonder if I'd be happier working on a ship. Then again, I'm so competitive, I wouldn't be able to relax until I was captain.
In Disgaea, when Flonne is introduced, she mentions she wants to be like a flower. At the end she's turned into a flower, although she's revived by Lamington or Laharl in the good and not-quite-so-bad endings.
In Disgaea 2, a mid-game encounter with the Prism Rangers has them identifying Adell as a demon, which is written off as a scouter malfunction. It isn't.
Also, Rozalin wondering if her father, Overlord Zenon is an imposter who tricked the real Zenon and has them locked away somewhere. It's revealed that Rozalin is the true Zenon's reincarnation; the fake Zenon kidnapped her and raised her as his daughter.
In Disgaea Infinite, the player finds out that Flonne is studying to become an Angel Trainee again. And in Disgaea 4, Angel Flonne saves the protagonists.
Strong Bad's Cool Game for Attractive People has lots of foreshadowing. For one, there's a Trogdor arcade cabinet sitting in Strong Bad's basement, but it doesn't work. The final episode has the machine being fixed as the first part of the plot. Also, the Videlectrix games in the first four episodes foreshadow the appearance of the characters from those games in the final episode.
The much-maligned plot twists of Final Fantasy VIII do get some foreshadowing during the game, although for the most part it's too sparse and hidden too well to be very effective. Most notably, Ultimecia's existence is heavily foreshadowed by the New Era Speech Edea makes when she takes control of Galbadia, but neither the player nor any of the characters have any way of understanding it since she's talking about events which will take place in the future. The orphanage reveal is likewise foreshadowed, albeit not very clearly, by both Cid and Irvine.
Psychonauts has two of these in the first level of the game, the mind of Coach Oleander. When you reach the white corridor at the end of his mind, the easiest to notice is the curtain, that hides the blueprint of the psychic tank Oleander wants to use to conquer the world, but there is another: if you look very closely, you'll find that the wall has a rabbit pattern. Oleander's Startof Darkness was the slaughter of his rabbits by his father, a butcher.
The Brain Tumbler Experiment has plenty of it. The passing under a bathtub labeled "Oblongata" (the name of the lake) to climb a tower covered in thorns trying to reach Loboto is obvious enough. The unique figments of a basket of milk bottles, a patch of flowers, a Napoleon hat, and a purple bull on the other hand are just figments until you make it to the real Thorney Towers.
Silent Hill 2 with some unsettling messages in the beginning parts of the game. "There was a HOLE here, It's gone now." and "The door that wakes in darkness, opening into nightmares." The messages point to psychological plot events later in the game.
Early on in the game when you meet Curtis Ackers he has a gas-powered circular saw in the back of his shop. Later, when the Order Soldiers abduct Alex's mother, one of them is armed with said saw, telling you ahead of time that Curtis is one of the bad guys.
In the opening stage, the doctor is sliced in half by Pyramid Head. The doctor is Alex's father, if you look closely, foreshadowing how he will die later.
The opening lyric of Soldier's Orders, Alex's theme song which plays early in the game, spoils the entire plot of the game.
Anyone with even a bit of military experience will be able to tell right away that Alex doesn't act at all like a soldier, and rather like someone who is faking the part. This was intentional, as it is meant as a hint that Alex was never actually a soldier to begin with.
Super Metroid foreshadows the final battle very subtly. Part of the world is the ruined Tourian from the first Metroid game, complete with Mother Brain's broken glass case. There is a secret room just beneath it with a few power ups to collect. Since there are hundreds of secret rooms in the game, the usual player won't give it a second thought, but after seeing Mother Brain's full body at the end of the game, it becomes clear that the room was there to house her huge body.
Metroid Prime does this much more directly with Meta Ridley's fight, not him appearing altogether - many of the scans describe what happened to Ridley, and of course, you SEE HIM right at the beginning of the game, then later on in Phendrana Drifts. Maybe it's obvious, but it worked very well as you knew eventually you would have to face off with him. Very well done indeed.
There is tons of foreshadowing throughout the Metroid Prime subseries towards the true nature of Phazon. Purportedly a meteor-borne mutagen, it's kind of weird that almost all Phazon-mutated creatures act with the same mindless aggression, and defend places of heavy Phazon concentration. The Chozo, the most advanced species in the galaxy, also act pretty afraid of something that's supposedly just a mindless material. All throughout the first Metroid Prime game, Phazon makes a distinct clicking noise. But in areas of heavy Phazon corruption, behind the clicking you can almost hear a sound like mocking laughter. And in the second Prime game, it becomes apparent that a Phazon meteor struck the Luminoth civilization. Isn't it an odd coincidence that the two planets hit by Phazon meteors both happened to be inhabited planets—and home to ancient, enlightened civilizations at that? Naturally, the third game reveals that Phazon is Sentient Phlebotinum bent on corrupting all life in the galaxy.
BioShock starts with the main character looking at a picture of his family, and he keeps seeing shots of his family in flashbacks throughout the game. It later turns out that his family isn't real.
"Would you kindly?"
There's some more subtle hints about Atlas earlier. If you take a moment to poke around the booby-trapped submarine that Ryan blew up, you'll notice a conspicuous lack of charred corpses for a vehicle that supposedly contained Atlas' family. There are also theater posters in Fort Frolic that bear the names Moira and Patrick, who coincidentally have the same names as Atlas' wife and child.
If you go poking around in the freezers in Neptune's bounty after defeating Peach Wilkins, you'll find the frozen bodies of two people stuck in a large chunk of ice. Melting the ice will reveal that they were tortured and murdered and attempted to write a message of warning that was cut short- "IT WAS F-". The first-time player won't think a lot of it until later when it becomes apparent that Frank Fontaine is alive. It's one of the first allusions to something especially unusual happening in Rapture, and is one of many instances in which Fontaine brutally eliminated anybody who discovered the truth in regards to his Atlas persona.
There's another one that occurs in two parts; when your first enter Rapture, there are signs on the wall that state that all bathysphere travel has been shut down. However, in the fisheries you can find an audio diary that mentions that anyone in the ballpark genetically to Andrew Ryan can utilize the bathyspheres regardless of a lockout. Later it turns out that the protagonist is very much in the ballpark - he's Ryan's son.
It gets better: In the opening cinematic, the player can faintly hear "Altitude. Altitude." as the plane goes down. This warning wouldn't be audible unless you were in the cockpit, forcing a crash. The biggest spoiler in the game, hinted at in the first minute.
Bioshock Infinite beating the game and playing through again is startling; almost the entire game is filled to the utter brim with foreshadowing that makes sense on replays or analysis.
When Booker first arrives at the tower, he sees a water tub with "Of Thy Sins Shall I Wash Thee" over it. Booker mutters under his breath "Good luck with that, pal." This doesn't become symbolic until later when you learn about Booker's rejected baptism. And, of course, the baptism that shortly follows sees Booker almost drown...
The blind preacher who baptizes Booker when he enters Columbia is the same one who tried to baptize Booker after Wounded Knee. The Booker we know refused the baptism; the one who accepted it took the name Comstock. For extra irony points, the preacher's first words to the player are "Is it someone new?" Answer: Nope!
Midway through the game when Booker is questioned by Elizabeth about Columbia, he says he never even knew about it before arriving. This is because in his universe, Comstock (and therefore Columbia) didn't exist.
When Booker first enters the Monument and finds the room with the Syphon, Elizabeth is humming an anachronistic version of Everybody Wants to Rule the World. Hmmm...
Songbird's eye cracks from the pressure of being underwater when it seeks out Booker. Note it's a relatively shallow depth, so when Songbird ends up at the floor of the ocean...
When Booker washes up on Battleship Bay he calls Elizabeth "Anna", which she refutes. Towards the end its revealed that she actually is Anna, given up by Booker to pay a debt. Maybe he subconsciously recognizes her?
While Booker and Elizabeth are walking through Battleship Bay a hot dog vendor offers a hot dog to Booker and his "daughter". Later we find out that Elizabeth is is fact Anna, the daughter he gave up.
The Columbia goon who gets Elizabeth to confirm her identity, so the Columbian Police can ambush Booker asks Elizabeth if her name is "Annabelle". She refutes this, too.
After being forced through a gauntlet of Slate's men, Booker denies the old soldier's claims that he's a hero, to which he responds "If you take away all the things that make Booker DeWitt, what's left?" The answer is: Comstock, that's what's left.
Throughout that entire area, Slate is constantly deriding Comstock because he believes that he was never the war hero he claimed to be. Slate is Right for the Wrong Reasons.
If Slate is given a Cruel Mercy by being left alive, Booker and Elizabeth later find him in the bottom floor of Finkton's police station, catatonic from lobotmization. Elizabeth, in the Bad Future, suffers this fate, but unlike Slate, turns just like her father.
Shortly before the nature of the Luteces is revealed, Rosalind can be seen posing for Robert, yet he's painting a self-portrait.
The true nature of the Luteces, the same person from two different universes, foreshadows that Booker and Comstock are just like them, except they're separated not by a single chromosome, but by a single decision.
In the bank, Elizabeth says Comstock's tithe is a whopping 50% of everything that comes in. Booker quips that he needs to get a job in the prophet business. Comstock, as it happens, is an alternate Booker who did just that.
Early in Columbia, the very first Voxophone Booker may find is Lady Comstock saying "Love the Prophet, for he loves the sinner. Love the sinner, for he is you." Accurate in more respects than you'll likely realise the first time you hear it.
When you meet Elizabeth face-to-face for the first time, the huge book she was about to smash your face with is titled The Principles of Quantum Mechanics.
There's one particularly telling dialogue between the two as they go to deal with Comstock.
Booker: I won't just abandon you! Elizabeth: You wouldn't. Would you?
Everything Comstock says to Booker. Comstock says Booker has a tendency toward self-destruction, and he's right in any reality - whether it's Booker drowning Comstock, Comstock abusing the Tears until he became sterile and sickly but absolutely at peace in the belief he would soon go to God, Booker gambling and drinking his life away, Booker allowing Elizabeth to drown him, and Comstock allowing himself to get beaten and drowned.
Everything Booker says to Comstock. Blind with rage, howling at Comstock for all his crimes against Elizabeth? Nothing but a pretext for Booker to express his profound self-loathing. Everything he says applies to him as much as Comstock. In that moment, Booker subconsciously wishes he could strangle and drown himself.
Following the first jump through to an alternate reality and finding Chen Lin alive, but disoriented to the point that he's unaware of anything happening around him, Elizabeth comments.
Elizabeth: Maybe... he also remembers not being alive. What would you do if that happened to you? Booker: I don't know. It already did.
Before that you encounter guards you had just killed in the previous dimension. They're disoriented, and all have nosebleeds. Chen Lin is shown to have one as well. After your second hop, Booker gets a nosebleed...
Comstock's prominent biography display in the center of the Hall of Heroes gives his birth year as 1874. Anyone who pauses to do the math on that will realize he's actually much younger than his appearance would indicate.
In the universe(s) where the Vox successfully rebel, you come across a sobbing, hysteric woman who is deathly afraid of leaping onto a barge, and possibly falling to her death below, while her husband tries to get her to take the risk, or she'll be left behind, which would be worse than falling to her doom. When the barge leaves, it's implied she did make it. When Booker's forced to relieve his attempt to get back his daughter from the Luteces, Rosalind is desperately trying to convince Robert to hop the small and unstable hole into the universe, and Robert is frozen up in fear and saying he can't go through with it, what if the gap closes and he's stuck between universes, or chopped in half...?
The song that Fink sings at the Raffle is "Goodnight, Irene". One of the lyrics contains "Sometimes, I've got a great notion / To jump in the river, and drown..."
When Daisy Fitzroy is about to kill Fink's son, she says "You see the Founders ain't nothing but weeds. Cut 'em down and they just grow back. If you wanna get rid of the weed, you gotta pull it up from the root. It's the only way to be sure—" right before Elizabeth plunges a large pair of scissors into her spine. In the end, this is exactly what Elizabeth and Booker do; they pull Comstock out by the roots to make sure he can never have existed.
In Fallout 3, you meet a Megaton citizen who is obsessed with the Enclave, believing that the American government will come and clean up the wasteland and restore it to it's former glory. Guess which government is corrupt and evil, and guess which citizen gets captured by them.
Your dad also says "Now I know you don't like it when daddy leaves you alone" to your Toddler self. The foreshadowing doesn't last very long, but it still fits the trope.
Leo Stahl has an addiction which he tries to keep secret. If you ask him what he does to entertain himself, he gets very awkward.
Galaxy News Radio often has news stories about sidequests that you can get. It's foreshadowing until you realize that he is talking about sidequests. He also makes references to meeting the player's Dad during the quest where you meet Three-Dog for the first time.
In the Point Lookout expansion, the tribal religion involves getting sprayed by hallucinatory spores from a plant and having a vision quest. While they're out, someone cuts open their heads and removes a chunk of brain. When the player does this, a chunk of his brain is removed as well. Later, someone else finds out that it wasn't a part of the religious ritual, it was just a madman taking advantage of their drugged state to have some fun. It was Tobar, the ferryman who brought you to Point Lookout. When you enter his shop menu to buy a ferry ticket, you may or may not notice that there's a scalpel, surgical tubing, a bonesaw, and tweezers in there for seemingly no reason.
Also, the vision quest itself involves a hallucination where a bonesaw cuts a rift in the ground in front of you, and then a needle and thread comes by to sew the ground back together again.
Knights of the Old Republic was very subtle. The Jedi masters say that normally they would not train anyone past a certain age, but you are a special case.
And that's only one instance. There are actually quite a few spoken lines that in retrospect aren't just coincidental foreshadowing, but in some cases actually talking about the event itself without actually spelling it out. When The Reveal is made, the cutscene flashes back to each character as they spoke these lines.
This is actually one of the brilliant things about Knights of the Old Republic which few people notice. The Jedi do not train past a certain age, but anyone playing this game will know about Luke Skywalker, trained when he was already a young man. The game plays on the players own expectations to make this moment less significant than it should be, meaning they don't have to try and hide the foreshadowing because the player has already hidden it themselves. They do say that they make very rare exceptions for adult recruits, but even then, the player is liable to assume this has more to do with the war thinning their numbers, the same way there would've been no more Jedi if Luke hadn't been trained.
In Ever17 it hardly seems worth pointing out the foreshadowing. If you play it, you'll look back from the final route and go OH! That's what that meant! Then if you play a second time, it's even more so because the entire story up to that route is foreshadowing. The lemur costume, the password, Tsugumi's jerkass status being inconsistent, the door she stopped Takeshi from touching, the pendant and even stuff like arguments over how many hot dogs there were. Everything. It's almost some type of one of the different aneurysm moment tropes except it's often minor and subtle.
Mass Effect did an excellent job with foreshadowing at the very first mission - when you talk to the insane scientist Manuel, it is very easy to dismiss what he's saying as the rant of a raving lunatic, but later on it becomes very obvious that the things he says are in fact visions of the reapers much like your own beacon-induced ones.Mass Effect 2 later did the same thing with a mad prophet, but in a more roundabout way.
In a much, much subtler example, it's mentioned in the Codex that turians wear facepaint to designate their clans. Those who wear no paint ("barefaced") are considered untrustworthy, as they don't make their allegiances clear. The Big Bad of the first game, a turian, is barefaced, but in the second game, the turian warden of the Purgatory has no paint, either, and soon betrays you.
In the beginning of the game, listen closely to the conversation you have with Doctor Chakwas and Lt. Jenkins. His comments are absolutely loaded with hints of what happens soon.
On your first visit to the Citadel, Ashley makes a comment about how the stairs leading up to the Council Chamber would make an excellent defensive position. During the endgame, you have to fight your way up those very steps to stop Saren from giving Sovereign control of the station.
Reading the codex reveals that biotics are sensitive to mass effect fields. Kaidan, a human biotic, gets an odd tingling in his teeth every time he goes near the statue of a mass relay. That's because it's not a statue. It's an inactive one-way relay created by the Protheans.
You probably won't notice it when you play the game for the first time, as it's not very visible when you don't know what you are looking at, but in Mass EffectSaren has the same blue glowing eye implants as the Ilusive Man in Mass Effect 2. Combined with the fact that the later is revealed as planning to use Reaper-technology to make humankind stronger, it's a very strong hint that he is already indoctrinated by the Reapers. Though he still seems to be able to fight it, as he still wants to destroy the Reapers in the second game.
In the same way, the weird visions Shepard gets from the beacon in the first game make a lot more sense after the big reveal at the end of the second. Reapers harvest sentient humanoids, dissolve them to paste, and use it as a building material to create new reapers. And that's pretty much what you are watching.
During Tali's Loyalty mission in Mass Effect 2, Admiral Zaal'Koris remarks that the other admirals would "see the fleet destroyed over the skies of their homeworld" if they went to war with the geth. In Mass Effect 3, if you choose the geth over the quarians, and are unable to broker peace, then this is exactly what happens.
For a more minor example, the Lair of the Shadow Broker DLC lists a song from the turian/quarian romance movie Fleet and Flotilla as a mainstay of your turian friend Garrus's combat playlist. In 3, if you aren't romancing either of them, he will have a Pair the Spares hookup with your quarian friend Tali.
In Mario & Luigi: Partners in Time, there is a secret room where the Baby Mario Bros. can visit Fawful, and listen to one of his long, maniacal rants. However, this could possibly be a foreshadowing of his role in Bowser's Inside Story.
Speaking of Partners in Time, there's one segment where the gate to the Star Shrine is getting on Luigi's case, refusing to let him past, and generally being a jerk. Turns out, he was just testing the brothers, and, before he lets them past, reassures Luigi that he's perfectly worthy to enter. One of the lines he uses is "Your heart is like a gemstone: multi-faceted and beautiful." I may be stretching it, but in Super Paper Mario you were carting around the dimension, collecting crystalline Pure Hearts... and the "ideal host" for the Chaos Heart is our plumber in green
Partners in Time also contains several hints that the Elder Princess Shroob is trapped inside the Cobalt Star. Toadbert's drawing is only the most blatant.
Super Mario Galaxy did this with the first two battles with Bowser. The first time you fight him, there's three small suns surrounding Bowser's arena. The second time you fight him, said arena is surrounded by dark matter that's disintegrating his castle. The third and final battle takes place inside a hollow Sun.
Shortly after Mario defeats Bowser for the last time by hurling him into that Sun, as he flies down to free Peach, in the background you can actually see Bowser Jr. fall into the Sun. The Sun immediately explodes and (almost) tears apart the entire universe.
Postal 2: Apocalypse Weekend. On Saturday, Postal Dude gets caught in the middle of a minor zombie invasion, which he jokingly suggests was caused by an outbreak of mad cow disease. Later, on Sunday, he gets a call from Running With Scissors head Vince Desi, saying that marketer Mike J has caught mad cow disease, and Dude has to take over marketing duties. At the end of Sunday, Dude faces the expansion's final boss: a giant zombie-cow-demon Mike J, or in his own words, "Kosher Mad Cow Zombie God of Hellfire!"
For fun times, take a drink whenever anyone says, "It's nothing." It's never nothing, it's something that if revealed would solve a lot of problems and make your life a lot easier. (Raine is so bad at this that her habit carries through to the sequel.)
Kratos being Lloyd's father is foreshadowed like crazy: Both of them dislike tomatoes. If you leave him controlled by the AI, he heals Lloyds at the drop of a hat. He is familiar with Lloyd's pet, Noishe. When visiting Lloyd's house, he will always be standing by his wife's grave. And so on.
The game hints that Botta and the Renegades aren't actually Desians using music cues. Normally when you fight a Desian commander it plays unique boss music, but when you face Botta it only plays the normal boss theme.
Tales of the Abyss has lots of lovely foreshadowing moments, many of them courtesy of Jade Curtiss, who knows more about the plot than you ever will. When Luke claims he was kidnapped and developed amnesia, Jade seems surprised and asks himself "could it be?" before insisting it's nothing. Later on he wonders if Luke and Ion are the same. And then, utterly without precedence, he says to Luke, "one day you may hate me so much you want to kill me." All of these together foreshadow the fact that Luke and Ion are replicas, created through the art of fomicry, which Jade himself invented.
The replica plot twist is also heavily hinted at by Asch. He looks quite similar to Luke, and has the same voice actor in English and Japanese. There's also a couple of conversations about replicas before the twist is revealed, including a detailed scientific explanation of how they work, and the moment where Van calls Luke a foolish replica.
Guy's origins are also very, very subtly hinted at. He has a conversation with Van that Luke overhears, but Guy won't tell him what it's about. It's a hint they're in cahoots. There's also the many, many times Jade calls him out on knowing extensive details about Malkuth's geography. It's because he's from Malkuth. By far the coolest one is a tiny background detail in his room in the Fabre mansion. There are banners with Kimlascan-looking heraldry hanging all around the manor. There's one over Guy's bed, but Guy has folded it so the emblem is blocked out. It foreshadows that he actually hates Kimlasca, and especially Duke Fabre.
The Tales Series is notorious for its Wham Episode addiction, so it's no surprise that Tales of Vesperia strikes again. The game heaps on the foreshadowing that Raven is Captain Schwann. There's a little Leitmotif associated with Raven that plays whenever he shows up. It plays in a scene in Heliord, for which he is not present... but Schwann is - Alexei asks him, presumably, to follow Estelle and Yuri. There's also the fact that he manages to stop the Schwann brigade by ordering them to attention - and they obey, recognizing his voice. And, of course, all of his weirdly existential musings about death make a lot more sense when it's revealed he's actually dead.
Tales of Graces continues the tradition. In the childhood arc, Hubert warns Asbel that he won't always be around to explain things to him. And he won't, because he's going to be adopted by the Oswells in Strahta, and won't see his brother for seven years. Sophie's true identity as a humanoid weapon and Richard's Demonic Possession are both also frequently hinted at, both by Richard's heterochromia (which he didn't have as a child) and scenes like the one where they join hands and both of them react like they've been burned.
Fate/stay night has this across routes. In one bad ending in the Fate route, for instance, Shirou is thrown out a third floor window and lands hard, only to then discover he is mortally wounded; not because of falling three stories, but because swords have erupted from inside his body. (Rather confused, he then dies.) The actual explanation for this really odd event isn't given until the final route, when it is revealed that Shirou instinctively projects when his body is badly damaged in an attempt to reinforce it; unfortunately, this instinctive projection sometimes results in swords being forged inside his body.
Yume Nikki has a very specific bloodstain on the floor at various points of the game. In the ending, the protagonist commits suicide by jumping off her balcony. We then see that bloodstain again, now knowing its cause.Why Madotsuki was dreaming up the bloodstains and the hair effect monsters that appear near them, we don'tknow.
In one Vanguard arc in City of Heroes, after Vanguard rogues have attacked your Rikti allies, you tell them that they were Nemesis automatons. Then in the next arc, you discover that the Earth heroes who originally attacked the Rikti homeworld, causing the Rikti war in the first place, were, in fact, Nemesis automatons.
Lord Foreshadow has nothing to do with the main plot and mentions no such thing. Tethoril is the one who spills the beans about the Antagonist. The only thing Foreshadow talks about is an upcoming trip and discussing the nights at Neverwinter....back when Neverwinter Nights was originally supposed to be connected with the Baldur's Gate series. Development hell and licensing issues caused it to become a completely unrelated game in the same setting with no mention at all to the Bhaalspawn Crisis.
Many people cite the spaceship and aliens plot twists in Ōkami as "Unexpected" and "Came out of fucking nowhere"... Forgetting that earlier, Kaguya leaves on a Bamboo shaped spaceship, doesn't sound like much, but this foreshadows a few things about the game you don't realize until the next playthrough.
For all the complaining about how General Shepherd's Face-Heel Turn in Modern Warfare 2 "comes out of nowhere," the article's entry on Foreshadowing consists of six bullet-points about things that hint about it earlier in the game.
Similarly, in Call of Duty: Black Ops astute players may wonder why none of your squadmates have any dialogue with Reznov, or how he can somehow beat you to the top of ladders even if you're the first to climb them. Then comes The Reveal that Reznov was your character's hallucination the entire time.
In Mother 3, on Tanetane Island, the entire party hallucinates after eating mushrooms. They meet several people who spout weird and often disturbing things, but one line stands out:
Hallucination!Claus: Yes! Okay, then I'll be at the very end!
Also, in Chapter 1, after Hinawa dies and Flint goes berserk and has to be put in jail, Claus has this to say:
Claus: I'm going to get so strong even Dragos won't stand a chance against me!
The Hummingbird Egg's purpose is hinted at in Chapter 5, when Duster picks up the egg and his amnesia is suddenly cured.
In Dragon Age: Origins, the Human Noble origin has your brother Fergus say some very innocent-sounding words to your nephew which has a chilling, portentous double meaning in retrospect.
Fergus:Don't worry, son. You'll get to see a sword up close real soon, I promise you. Could also qualify as Black Comedy or a "Funny Aneurysm" Moment depending on your sensibilities.
In Dragon Age II, offhand comments that Knight-Commander Meredith became significantly more reclusive and started becoming more fanatical right around the time you lost track of the Obviously Evil red glowy Artifact of Doom should have set off every alarm bell in the Genre Savvy player's head.
And there's a hell of a lot of foreshadowing surrounding Anders and his downward spiral. Several show up during the "Justice" quest, including one unusual bit of foreshadowing via pun: as Anders is leaving the Chantry, Grand Cleric Elthina tells him that she hopes it was "a balm for his soul." Eep.
From the same quest, there's also this statement: Mix the ingredients together and boom!...Justice and I are free.
He's got some foreshadowing during his first appearance in Awakening regarding the same event. When you are in the Silverite Mines and see some darkspawn underneath a religious statue which can be destroyed with a ballista, Anders cheerfully remarks "I'm always up for a bit of iconoclasm." Considering that Awakening was being written at the same time that Dragon Age II was being planned, this is probably no accident. (One imagines the writers snickering evilly.)
Oh, geez, if that's the case one should also look at every single conversation Anders and Justice and Nathaniel and Justice have in Awakening. They foreshadow that Anders will absorb Justice pretty damn heavily. Justice tells Anders he should take up the cause of oppressed mages and try and liberate them; Nathaniel asks Justice if he could potentially possess a living host. Bioware knows their stuff.
In BlazBlue, Hakumen's Shipuu (Squall)Distortion Drive is a slower, stronger version of Jin's Touga Hyojin (Arctic Dagger) Distortion Drive.
Even Continuum Shift has this too. In the Arcade mode, Taokaka (the player) fought Litchi in an NOL base rather than Orient Town. And Litchi's Arcade, she knew Noel's position of Lieutenant, even if she didn't know it throughout Calamity Trigger. This was later revealed that in the Story Mode, she joined NOL thus could be spotted at the base or knows Noel's position.
Deadly Premonition is crammed full of foreshadowing, much of which is easy to miss the first time through. Playing the game a second time, it is astonishing how many seemingly innocuous details are actually foreshadowing: The doll of a fat man in the White Room. FK in the coffee. All the comments about York's scar. The red tree growing in George's backyard. George is a passionate man. The "Love G" tattoo. The potted plant Kaysen carries around. The picture in Harry's mansion of Emily with the goddesses. The fat man among the military members in Harry's story. Leads to a ton of Fridge Brilliance when you complete the game.
Singularity is extremely upfront about its foreshadowing, with the player finding messages scrawled on the walls everywhere that say things like "It's still not fixed" and "we've already tried" and even "What if this is supposed to happen?" That this is a time-travel story gives these messages an almost-obvious status as markers of a Stable Time Loop or "Groundhog Day" Loop, and to make it even more obvious, the messages are so old they've faded away...but they're scrawled in the game's Unobtanium, which means they must be meant for the player, because only the player's time-manipulation device can revert the ink back to its pristine state. It turns out the messages are actually as true as you initially assume, but this lulls you into a false sense of security, because the Stable Time Loop isn't what you think it is.
In Episode 304 the Telltale Sam & Max: Freelance Police games, Girl Stinky is making out with her secret lover Sal, a six foot tall cockroach, and the titular heroes witness this. When the lovers notice them, Girl Stinky calls Sam and Max Droopy and Stitch respectively. At the end of the episode, guess the resemblance Max has to after his transformation and Sam's resulting reaction...
Maximillian Roivas learns some real disturbing things about his mansion at some point in his life - like, for instance, that it's built on top of a city predating humanity. Eventually, he descends into the depths of his mansion, and he gets a glimpse of a prison cell from the inside before he gets too far. After killing one of the abominations in his expedition, he goes right back to the surface to garner military aid in its further exploration.No points for guessing what happens to the poor guy.
The game opens with Alexandra having a dream where she fights several zombies while trapped in a dark room. Towards the end of the game, she ends up entering that same room in the family mansion to retrieve an important item, and discovering that it was where Maximillian slaughtered several of his servants on suspicion that they'd been possessed by Bonethieves.
There is an Easter Egg in Red Faction: Guerrilla in which you can meet and talk to Parker, the protagonist from the first game, who is now an old miner. One of the things he says is "But you don't see monsters around these parts no more... Unless you look real hard." In the upcoming sequel, Armageddon, a group of explorers end up doing exactly this, uncovering an old Marauder base, and releasing a horde of monsters into the underground.
The opening cinematic of Starcraft2 makes it clear that Tychus Findley is a double agent working for Mengsk. What isn't so clear is the specific task Mengsk gave to Tychus. However, everything Tychus says and does throughout the campaign foreshadows his true objective: kill Kerrigan.
In the CLANNAD visual novel, during Yukine's route, she tells Tomoya with one of her spells/fortunes that "Other people's happiness will become your happiness." During the game, you go into each characters route, ending off by improving some aspect of their lives or making them happy, and obtaining their "light orb." These "light orbs" are needed to get the "Good End" of the game where Nagisa and Ushio live.
Brilliantly used in the opening cut-scene for Conkers Bad Fur Day. While the music that plays has been associated with A Clockwork Orange, it was originally written and used for a funeral procession for Britain's Queen Mary II. Considering that Berri would have likely been Conker's queen at the end had she lived, the context in which the music was used suddenly takes on an appropriately grim tone for players familiar with the piece's origin.
Used frequently in Kingdom Hearts. A piece of scenery in the first game foreshadows the "five betraying apprentices" that form the backbone of Organization XIII, a drawing in Kingdom Hearts II foreshadows Xion's presence in 358/2 days, Chain of Memories foreshadowed II heavily (it was almost more foreshadowing than actual plot), and in II, Xemnas' violent reaction to being called Xehanort foreshadowed a major lategame plot twist of BirthBySleep.
In the first game, idling on the title screen will bring up a cinematic composed of scenes from the game with sentences between each. These sentences are Kairi's letter from the end of Kingdom Hearts II.
If you turn subtitles on, you may notice that sometimes, GLaDOS says something where the subtitles say "[garbled]" and the other way around. However, one notable occasion is when GLaDOS says "The Enrichment Center is required to remind you, that in the end, you will be baked, and then there will be cake." The subtitles say "The Enrichment Center is required to remind you, that in the end, you will be baked [garbled] cake."
On one of the director's commentary tracks you can play during the game, the makers state that this above quote was an accident. They planned for the quote to be "You [Garbled]...baked...then there will be cake" but someone screwed up in post editing and the line was never edited so the game got released without them realising.
"The Enrichment Center is committed to the well being of all participants. Cake and grief counseling will be available at the conclusion of the test. Thank you for helping us help you help us all." Why would you need 'grief counseling'? Could it be because the Companion Cube is going to die?
"When the testing is over, you will be... missed." But not just because you're an excellent Test Subject.
In the trailer for the sequel, Cave Johnson was not kidding about Aperture Science selling crushers.
The Portal 2 final battle has some very immediate foreshadowing: one of the personality spheres is obsessed with going to space. A few minutes later you portal to space.
Earlier than that, one of Cave Johnson's audio blurbs mentions that the white paint that allows portal placement is made out of moon dust.
Even earlier, a Turret that says "I'm different" can be picked up on a conveyor belt. If you save the Turret from destruction, it will actually foretell the events of the rest of the game, though not much of its hints will make sense until they happen.
"Don't make lemonade!"
"Prometheus was punished by the gods for giving the gift of knowledge to man. He was cast into the bowels of the Earth and pecked by birds."
"It won't be enough."
"The answer is beneath us."
"Her name is Caroline. Remember that."
In Trauma Team, one of Gabe's patients wears primarily black clothing with an easily-missed rose motif, foreshadowing her affliction with the Rosalia virus.
Pokémon Red and Blue has an example in the Viridian City gym, which although it's the first gym you see, it's actually the last one you battle in. It is closed for most of the game.
During the prologue of Pokemon Mystery Dungeon Explorers of Time/Darkness/Sky, just right before the first scene in the game appears (it's that of the hero, now transformed from a human into a random Pokemon and being washed ashore), for a few split seconds, several diagonal lines can be seen moving extremely fast across the screen as if someone was slashing the camera, followed by someone (probably either Grovyle or the hero) screaming (it's completely blank when this happens). Later, toward the middle of the game, just right before the hero and his/her partner fights Dusknoir and his Sableye, Grovyle actually tells the hero that Dusknoir is a villain and and that he is the hero. He also tells him/her that while he and the hero are travelling to the Mystery Dungeon world, someone must have separated the two during their journey. These two scenes actually give away the existence of the game's (real) Big Bad, Darkrai, who was actually responsible for the hero's transformation into a Pokemon.
Sonic Battle: Emerl's quote "Show me your power. Or I shall not obey. I represent all things, and shall become Gizoid, the conquerer of all..."
There were several nice Continuity Nods in A Crack in Time, which was to be expected, being the third of a trilogy and all, but looking back on it, there's clear foreshadowing from Tools of Destruction to ACiT. The most obvious is set up on Planet Reepor after Qwark gives Tachyon the Dimensionator. The Dimensionator lets loose a shockwave as it's fired up and knocks Ratchet out. This leads up to a scene where the audience is shown Clank reaching for Ratchet, as the latter falls into an abyss. This is repeated, minus Dimensionator and Cragmites, in the climax of ACiT. In addition to this, the still for the pre-final boss cutscene in ToD's cutscene viewer is suspiciously similar to part of the cutscene The Last Lombax from ACiT.
Looking back on Tools of Destruction, there were several clues leading up to Azimuth's introduction in A Crack in Time. The most obvious is the "Court of Azimuth", which many fans caught onto, but more subtle is the optional Q&A session with Aphelion, once she's repaired. If you go through all of the information, she explains that Tachyon was granted access to the Lombaxes' technology and then used it for his own purposes— getting rid of the lombaxes, that is. It's not terribly surprising to learn that Azimuth was responsible for this, given his motivation in ACiT
In Folklore, an apparition of Herve from seventeen years in the past says that what he really wants for a gift is an issue of the occult magazine Unknown Realms, which he says is very hard to find because, according to his father, it doesn't sell and is on the verge of shutting down. This gets a wry reaction out of Keats, who writes for the magazine in the present. This scene is an early clue that Keats isn't what he thinks he is: he's a Halflife, a being created by the strong wish of a human (Herve, in this case). The real Unknown Realms magazine is long gone.
Half-Life 2: While showing Gordon around Black Mesa East, Alyx stops in front of a dark corridor and says...
Alyx: That's the old passage to Ravenholm... we don't go there anymore.
Magolor: This baby can cut through dimensions! And it can fight... if necessary.
Guild Wars has a fair number of these if you know where to look.
The Flameseeker prophecies are mentioned often in Ascalon and foretell several major events. Meerak the Shouter in specific foretells the death of Rurik; the danger of the Mursaat; the betrayal of Khilbron or Markis; and the return of the Titans.
Even earlier, the effigies raised by the Charr are made in the image of the end-game Titans.
When Togo wishes he could spend more time talking with Vizu, she promises him there will be more than enough time to do so after Shiro's defeat. Togo is killed fighting Shiro and returns as a spirit in Tahnnakai Temple, where he can speak with Vizu for eternity.
Miners in Joaknur Diggings had their eyes destroyed and, on her death, a servant of Abaddon declared "Abaddon will eat your eyes". Not long after, the Hunger captures Kormir and devours her eyes.
Brain Dead 13: Combine that with Rule of Symbolism: During the intro, while Lance's voice speaks to Fritz about his computer problems, there is a purple spider in the darkness that is chasing an inchworm with big eyes and red hair, seemingly devouring it before it returns to life and gets chased by said spider again. This definitely foreshadows the whole Chase Scene, as the purple spider symbolizes Fritz, and the inchworm symbolizes our hero himself.
In killer7, in the battle against the Handsome Men, each of the Smiths fights a Handsome who corresponds to them in some way. Handsome Red is initially presented as their leader, but at the end it turns out that Pink is the one running the show. Now, consider the fact that Harman fights Red, while Garcian takes on Pink.
Syndicate (2012): There are several conversations and text collectibles setting up the Church of the New Epoch (the antagonists of Syndicate Wars) as potential villains in a sequel. The infobank entry on ballistic shields mentions a Eurocorp memo to switch to liquid polymer defences, foreshadowing the liquid armour troopers.
In The Legend of Zelda: Skyward Sword, Zelda regularly sings a song titled "Ballad of the Goddess," which also happens to sound exactly like Zelda's Lullaby played in reverse. Partway through the game, she is revealed to be the human reincarnation of the goddess Hylia.
Before the second fight against Ghirahim, he turns his arms black and boasts that they're now "stronger than any armor". The final fight against him reveals that he's a personification of Demise's sword, possessing a metallic body that can't be harmed directly by Link's sword.
Parodied in The Legend of Zelda: Link's Awakening; Papahl outright tells you that he'll get himself "lost in the hills later", and so asks you to keep an eye out for him. Sure enough, after a certain point he leaves the house and can be found in the mountains at the north, where you have to give him a pineapple as part of the game-spanning Chain of Deals.
Duel Savior Destiny tends to be very unsubtle about what things are going to be important in the future. For example, when Nanashi joins all the background authority figures are talking about her and she drops hints everywhere about being much more than she appears.
Spec Ops: The Line: After the helicopter gun-rail event, Capt. Martin Walker has a hallucination. At the end, he sees John Lugo calling for help while a sea of buried civilian corpses drag him down in the sand. Not long afterwards, Lugo is on the radio begging for back up because he's surrounded. However, when Walker and Alphanso Adams get to him, they find out too late that Lugo was killed by a civilian mob, not the 33rd. If you choose to honor Adams plea, you can slaughter the civilians around Lugo afterwards, completing the vision.
In Kid Icarus: Uprising, during the invasion of the Aurum, sun god Pyron quotes "The Book of Divine Prophecy" to explain who they are and why they need to be fought. Nature goddess Viridi specifically says that she doesn't remember that part of the prophecy... and she was even mentioned as an expert fortune teller one chapter prior. Pyron turns out to be using the other gods to distract the Aurum to try and take control of them.
In Borderlands 2, when you first meet Roland in his prison cell, the wall behind him says, in blood, "You die". Guess who dies.
Like the original game, the new vault hunters are helped by the powerful AI named Angel. Whenever the AI uses her powers to aid the vault hunters on their quest, she uses "Phase" powers. Phase powers can only be used by Sirens.
Fallout: New Vegas featured a pile of wrecked cars in a dead-end with the graffiti "Courier Six", "Lonesome Road", and "The Divide", hinting that this would later become the entrance to the Lonesome Roadexpansion pack, which was also foreshadowed along with Old World Blues at the end of Dead Money, the first DLC, and in the main game when Johnson Nash talks about the original Courier Six(Ulysses) who turned down the Platinum Chip delivery, and says "I hope a storm from the Divide skins him alive". Ringo mentions leading a caravan to New Canaan, which you attempt (and fail) in the Honest Hearts DLC. There, Joshua Graham also speaks of the "other" Courier as well as Big MT and the Divide.
Early in Dungeon Maker II: The Hidden War you hear stories of a rampaging dragon on the loose that ends up dying in a battle with the royal navy. On floor 8 you fight an undead dragon with a ship's mast impaled through it from shoulder to thigh.
