[[WMG: XCOM's Commander is the pilot of the Skyranger aka [[NomDeGuerre Big Sky]].]]

Whenever the Skyranger is on-route to or from a mission you are unable to issue commands at base because you are not at base you are flying. This explains why commutation from Bradford are transmitted over radio rather then in person. This might be an explanation why you can only have one Skyranger as there is only one of you.
* Alternately, you aren't the pilot, as he reports in to Bradford at the beginning of each ground op. Of course, there's nothing stopping you from taking the navigator's seat and directing the squad on-site. That the Skyranger is capable of offering a similar aerial viewpoint to what's used in-game is just icing on the moist, low-lag communication cake; hell, Big Sky is even a fitting callsign for a commanding officer.
[[WMG: The Representitive of the Council is Agent 47]]
Really, the only evidence of this is the BaldOfAwesome but it does paint an interesting picture of either the Council finding the most badass being they could find to represent them or Agent 47 running around the world threatening people into supporting XCOM.
[[WMG: Chrysalids normally don't hatch as fast as they do on missions]]
It appears as though Chrysalids have a very short maturation time from what we see on terror missions, this would make them useful as an invasion species. However during the Finland mission we see them maturing much slower inside of the whale, various sharks, and human hosts. All of this leads this troper to believe that under normal circumstances the mature for a number of weeks maybe even months but when there host is disturbed by weapons fire or physical attack they hatch early and malformed which is why the ones on terror missions who hatch from civilians are a different color. If left alone after a few days the quick grown off-white ones woulds simply die from not having formed most of there organs properly where as the ones in Finland could have lived indefinitely/the average properly formed Chrysalid life span. This would make sense in an evolutionary way, you don't want your young to be defenseless, and in an invasion sense. So you make them capable of injecting a fresh parasite and living at full strength for a brief time if disturbed.

[[WMG: MEC Troopers eventually gain back the ability to use emotion in their voice]]
I personally think that, if the MEC trooper process really made humans permanently unable to use such an important part of their voice, Dr. Shen would have considered it "crossing the line" and never fully developed it.
* This Troper finds it unlikely that MEC troopers speak like that when wearing their Base Augments while off duty. Everyone seems to have forgotten that [[VideoGame/StarCraftI Goliaths]] spoke in exactly the same way back in 1998 as MEC Troopers in XCOM do today, and yet Goliaths were a piloted mech suit with a normal human inside of it. In both cases, the out-of-universe reason for it is [[RuleofCool Rule of Cool]] and the in-universe reason probably has something to do with ease of unit identification or a need to amplify the voice to compensate for the human being stuck inside a walking metal coffin that will tend to retain sound.

[[WMG: Meld actually isn't part of [[spoiler:the test]]]]
Meld is distributed early-game, and none of the alien units show any sign of having Meld (except for possibly the [[spoiler:Mechtoids]]) worked into them. It is possible they were really just seeing what would happen, and had no idea the humans would exploit it.
* MELD can be used to bond organic tissue with mechanical parts. Floaters at least would likely use some (supported by the fact that Heavy Floaters drop some MELD when killed), and most other organic aliens have some sort of cybernetic implant.

[[WMG: Gene-modded soldiers will pass on the mods to any offspring they have]]
Simple enough; there's no indication that, unlike MEC troopers, that said troops give up their humanity in any form, they just simply become humans-with-extra-stuff. And because it's ''gene'' modding, it effectively means that whatever mods you've given them are now written straight into their genetic code.
** genetics don't work that way. if a person has skin cancer on there arm (a genetic modification via solar radation) there children won't be born with skin cancer on the same point in there arm. in order for a genetic trait to be inheritable, the Sperm or Eggs of a human must be modified, not say the muscle tissue of a arm or a leg.
** And who says that Meld Gene mods are accurate enough to only target the affected area, and not change the entire body, including sperm and eggs? After all, the would be Gene Trooper is held in a tank full of Meld...

[[WMG: [[Series/GoodEats Alton Brown]] is a Thin Man]]

Look at [[http://upload.wikimedia.org/wikipedia/commons/6/67/Alton_brown_2011.jpg that face]] and tell me he's not!
* That's about the most awkward looking picture you could have possibly found of Alton Brown... but then my science teacher looks exactly like Alton Brown, so there maybe some truth to this...
Just going to drop [[https://s-media-cache-ak0.pinimg.com/736x/53/f2/ef/53f2efb94a67735aa2732098a8d8c78e.jpg this]] here...

[[WMG: Cydonia is for the sequel or for a post-endgame DLC.]]
* Pretty self-explanatory.

[[WMG: The Ethereals are only the latest batch of host bodies]]
* The Ethereals refer seemingly to themselves as the "greatest failure of the Ethereal Ones". They explain that their physical forms are too weak to be sustainable. Humans, being both psionically potent and physically durable, represent their greatest hope - hence their intense disappointment at failures of the squad on the final mission. It would seem the Ethereals themselves may be, as their name implies, bodiless psionic entities that move between hosts. Realizing their current forms are too weak, they have been attempting to engineer or discover a new host species, with humanity as their brightest new candidates.
** Pretty much confirmed by XCOM: The Bureau
** Alternatively, it's possible the Ethereals' bodies are their original ones, but they may still be planning to "move out" into human bodies after all their other candidates proved unsatisfactory. Either way, what they imply "lies ahead" could be the imminent Ethereal mass-possession, or it could be something else.

[[WMG: Where did the snakemen go?]]
* Snakemen were oddly missing from the remake. There was also only one addition to the roster of new alien species. The Thin Men. Which are reptilian in origin. Thin Men are literally genetically engineered Snakemen. There's where they are. Now to go prove that the cafeteria food in XCOM headquarters is actually celatids and silacoids.
** Confirmed.
*** The cafeteria food has been confirmed? [[ScoobyDoo Jinkies]]!
** Cyberdisk autopsy reveals that they contain silicon-based organic components. It seems the Ethereals found plain old silacoids unworthy...

[[WMG: The Volunteer survived]]
* As did all the other members of his/her crew. S/he IS the most powerful psychic ever to exist of all time, afterall. Whose to say s/he couldn't shield them all from the cataclysmic explosion and become a god?
** Maybe it's because I ship my two psychic colonels together and they were the only survivors... Then again, battle hardened psychic space lesbians is a great ship.
** That may be the most awesome ship this troper has ever heard of.
** The Volunteer surviving may be a WMG but the rest of the crew surviving isn't. The cutscene clearly shows them flying away as the ship blows up.
*** The Volenteer actually pushes at least two of his/her team onto the Skyranger with their mind...
* Confirmed with [[https://twitter.com/SolomonJake/status/535236820221841410 this tweet]] from Jake Solomon, the Lead Designer of XCOM Enemy Unknown.

[[WMG: The Volunteer ascended]]
The Ethereals wanted someone powerful and durant enough to do what they could not. One of the things they couldn't do was ascend ( to some higher state of being, presumably ). The Volunteer, though? Totally did it, after saving the planet.
* There's a [[Franchise/StargateVerse Stargate]] crossover in there to be written.
** This troper heard of [[{{XSGCOM}} such fanfic's existence]] (Based on classic X-Com though) and can recommend it to everyone who likes either franchise.
** Considering that the alien temple ship was suppoedly forming a black hole and it exploded instead...where did the energy go? It can't be destroyed, only converted...such as shoving a psionic being into the next realm.

[[WMG: None of the squad sent on the final mission survived.]]
That drop ship just took off rather quickly, I don't think the survivors of the squad would have had time to make it back before it left, especially since it explicate mentioned the "package" wasn't on board. As The Volunteer was pulling that heroic sacrifice, the rest of the squad probably made it back to the drop zone just in time to see the earth they spent so much effort protecting fade away before the final boom.
* I think that they did survive. The "package" that the pilot references is the Volunteer, the rest of the squad makes it back to the Skyranger just in time. But then I'm an optimist.
** Their death wouldn't make sense from a narrative standpoint, as it would render the scene where the Volunteer telekinetically pushes them out through the closing door of the final chamber kinda pointless.
*** Seems pretty obvious that they made it out...they got shoved telekinetically and were possibly pushed psionically back to the Skyranger, it took off with everyone on board.

[[WMG: The final mission is a metaphor for the entire franchise]]
* The Volunteer (The New One) represents XCOM: Enemy Unknown.
* The "Failures" are all metaphors for the previous games in the franchise to try and live up to the original game's success. Some got farther then others, but in the end, none of them reached it's level of quality.
* Mutons are Enforcer
* Chrysalids are Terror From The Deep
* Sectoids are the FPS
* Sectopods are Interceptor
* The Thin Men are Apocalypse
* The Ethereals, the best of them all, represent the original game.
* They have been looking for a true success for years, and they have found it in the form of....The New One. The only one to reach such power and such success.
** Drones could be The Bureau, looking a little better than the original FPS (having a few more tricks up their sleeve than Outsiders/Sectoids such as repairing other mechanical units), but still ending up SoOkayItsAverage at best.
** Wouldn't Outsiders be the equivalent of the FPS? Outsiders are inconsequential, forgotten shortly after discovery, and ultimately nothing more than a lead to something bigger and better. Sectoids could represent various X-Com remakes and fan sequels--weak (lacking budget and veteran programmers) and cruel (hewing to older game design styles and presentation against all logic), but at least they've got the Gift (fan-love and creativity).
*** Not to mention that the outsides are very similar in portrayal to the mechanical enemies in the fps, created a mechanical body from light and energy.
** EXALT could be any source of ExecutiveMeddling in the series, as they appear to serve on the side of good (Giving life to the game and advertising it), but they just end up undermining the whole thing.

[[WMG: Future DLC will add missions that have your squad rescue one or two important Hero Unit like soldiers to join XCOM. They will possibly be cross over characters from other game series]]
Candidates so far include one of the main characters from a VideoGame/DeusEx game, and Wei Shen from ''VideoGame/SleepingDogs''.
** Those are Creator/SquareEnix games, XCOM is 2K. Besides we already got a triad member in the DLC.
*** Somewhat true. One DLC mission involves rescuing a defecting Triad member who then joins your squad as a heavy.

[[WMG: When modding tools are released, Valve will release a mod that does one of the following:]]
* Adds a minigame where [[VideoGame/TeamFortress2 the RED team]] fights an endless horde of aliens.
* Adds a council mission where you have to retrieve a fallen [[VideoGame/{{Portal2}} Space Core]], much like the ''Skyrim'' Mod "Fall of the Space Core Vol. 1".
* Adds an council mission where you escort [[VideoGame/{{Half-Life}} Gordon Freeman]] out of Black Mesa. He then joins as an assault-class character.
** What about one that adds [[VideoGame/Left4Dead Tanks]] as spawns from a new "Elite Chryssalid"?

[[WMG: Future DLC will add more classic aliens to the roster.]]
Fingers crossed, anyway. Snakemen would be the Elite analogue to Thin Men--perhaps sporting more snakelike special abilities (constriction, anyone?). Monoliths (the big floaty geometric shapes) would be upgrades to Cyberdiscs (or Outsiders, depending) and have a heat ray attack similar to, but weaker than, the sectopod's. Silacoids will cause rampant environment destruction against the player's favor. Celatids can suppress with acid spray and inflict poison a la thin men. Reapers are faster but weaker muton berserkers.
* What Monoliths? No X-Com game had anything remotely similar.
** I think it's referring to the aliens from the earlier FPS videos.

[[WMG:Scatter lasers are pumped in order to facilitate cooling.]]
Since scatter lasers pump out multiple beams from refracted lenses, they require a mini-cooldown after every shot. The pump forces refrigerated air into the system, cooling it enough to make another shot.
* Alternatively, it's a cleverly-veiled reference to [[http://en.wikipedia.org/wiki/Laser_pumping Laser Pumping]].
* Or, there are several batteries in a clip, and each shot discharges the battery, which would explain the heavy damage the weapon does compared to the regular laser rifle.
* Another possibility is that the pump itself generates the charge for the next shot. Kinetic motion, like a windup flashlight
** OR the designers didn't bother to change the animations for the weapons.
** Or [[RuleOfCool the people designing the games]] (or the lasers) [[RuleOfCool thought it would be cool]].

[[WMG: Berserkers are the natural state of mutons.]]
The Ethereals themselves state that the Mutons were basically a pack of angry, violent cavemen, and so stepped in to take them over. My hypothesis is that the typical muton is guided by an ethereal somewhere on the Temple Ship, applying tactical know-how and guidance so it doesn't just bash targets over the head with its gun instead of shooting them. Berserkers are mutons too willful to regularly control, so they're given spiked knuckles and heavier armor and allowed to do their thing.
* Alternatively, your run of the mill Muton are just pumped full of over dose levels of sedatives (by human standards anyway) which dulls their blood lust to allow them to be at least semi-tactful during missions.
* Partially contradicted by the game- autopsy a Muton Elite and you'll learn that the Ethereals simply dump war doctrine and tactics directly into the Muton's mind. Berserkers being largely unchanged from their original state makes sense though.

[[WMG: The DLC hinted at by the Steam Achievements list is a Terror From the Deep add on.]]
Some of the Achievement pictures have a distinct water theme (the dam and the faucet). How awesome would it be to be fighting the Aliens on land and sea at the same time!
* Jossed. The DLC, entitled ''Slingshot'', will be set in China instead.
** Who says there will be only one DLC? TFTD would make an awesome sequel game though. But then again there's always Cydonia...

[[WMG: The Council are agents of the Ethereals]]
* To all outward appearances, the Council is a ReasonableAuthorityFigure working to thwart the alien invasion. But consider the following:
** They certainly give off the "creepy shadow organization" vibe.
*** That trait is mandatory in every [[TheOmniscientCouncilOfVagueness shadow council]] in any series. Just because they're odd doesn't mean they're mind controlled.
** The Council continuously drives the XCOM project to push humans to the limits of their abilities (and beyond), using technology recovered from the aliens.
*** It's not the Council that encourages XCOM to evolve: they never ask you to do anything apart from the general goal of "stop the alien invasion" and occasionally escorting [=VIPs=]. Theoretically, you could do the game without upgrading weaponry a bit and only having one psi-soldier, and they'd be peachy if you were still winning. It's '''you''' that doesn't want to go up against Sectopods with regular firearms, like the '''Ethereals''' want you to.
** Most of the Council missions exclusively involve Thin Men.
*** They're infiltrators. You're going to accomplish an objective. The aliens' infiltrator scouts alert the rest of the aliens to your activities, and they try to stop you. What does this even prove?
** The invasion tends to scale up staying always just one step ahead of XCOM.
*** The ''Aliens'' are intentionally scaling up for [=XCOM=] specifically. They won't need the Council's updates on your progress; if certain aliens are getting trounced easily, send a stronger one. Plus, if the Council is keeping them appraised, why the hell did they send me to a terror mission when I hadn't upgraded any armor or weapons and all I had in reserve were 5 squaddies?
** We never see the Council members' faces. (They could be cooperative humans, mind-controlled humans, or even Thin Men)
*** The cooperative humans and Thin Men theories are Jossed, as the game over screen shows the spokesperson for the council being mind controlled by a Sectoid Commander. It doesn't say that [[ExactWords they've only been mind controlled since the project was abandoned]], however, so the theory over all is still valid.
*** If they're already mind controlled, what's the point of obviously mind controlling them an additional time?
** As stated in TheReveal, the Ethereals staged the invasion to uplift humanity and prepare them to fight the BiggerBad.
*** Again, it doesn't mean that the Council is in on it.
** "Remember, ''we'' will be watching." (Who is "we", exactly?)
*** The Council Members. [[AskAStupidQuestion Duh]].
* If XCOM succeeds in stopping the invasion, the Ethereals plan to use the uplifted humans in their army. If it fails, the Council pulls out and the aliens presumably subjugate humans as another of their failed attempts. Either way, the Council is actually working for the Ethereals, playing the [[GoodCopBadCop good cop]] role and using the XCOM project to advance the Ethereals' agenda!
** Extremely unlikely. Apply OccamsRazor for a second. Sounds like a lot of conspiracy theories saying that all the governments are controlled by one body and whatnot.

[[WMG: Alternately, the Council was ''started'' by Thin Men and Sectoids, and the entire XCOM operation is a XanatosGambit]]
* It turns out the Thin Men and Sectoids are looked down on by the Ethereals. If XCOM succeeds, they are freed from the Ethereals' rule. If XCOM fails, they can take credit for a successful invasion, potentially gaining respect from the Ethereals.

[[WMG: The Various Enemies are a ShoutOut to the ET races that are rumored to allegedly exist in conspiracy theories and urban legends]]
* Sectoids are Grays
* Thin Men are Reptilians
* Chryssalids are Mantoids
* Outsiders are possibly fifth dimensional/density energy beings
* Sectopods, Floaters and Mutons are the only ones that do not have a counterpart in the urban legends
** They may not have urban legend counterparts, but the Sectopods might be [[StarWars ATSTs]], Floaters and Mutons might be [[Franchise/StarTrek The Borg and Klingons]], respectively.
*** Really? I saw Sectopods as [=ED209=] from Robocop.
* Etherals are Annunaki
* Is this really a WMG? It's pretty obvious what they were going for.

[[WMG: The Volunteer survived, [[AscendToAHigherPlaneOfExistence and shifted into Fifth Density]] after his HeroicSacrifice]]
Essentially doing what the Etherals could not.
* Covered above

[[WMG: The Etherals are trying to prepare Humanity for [[Franchise/MassEffect the Reapers]]]]

The Etherals were a race that the Reapers attacked and nearly wiped out, to the point where only a couple hundred thousand are still left. They spent the 50,000 years since then traveling the galaxy, trying to find a race that they could uplift that would have a chance at beating them. Because HumansAreSpecial in both Mass Effect and XCOM, they were the appropriate choice. And if Mass Effect has proven anything, people tend to ignore the existence of the Reapers until they were right on their doorstep, so the Etherals attacked Earth themselves, forcing Humanity to unite under the Council (The Human one) and forcing them to develop more advanced technologies preparing them for the Reapers down the road, not to mention causing Humanity to become much more militaristic with them under the assumption that all there is an empire of aliens out in space waiting to conquer them. When the Reapers eventually show up, Humans will be centuries or maybe even millenniums ahead of what they were expecting.

* This idea is GLORIOUSLY explored [[Fanfic/XCOMSecondContact here]]
* Alternatively, the threat the Ethereals speak of is the [[VideoGame/StarcraftII Dark Voice]]

[[WMG: Soldiers recruited from the greater United Kingdom are former Series/{{Torchwood}} members.]]

All of Torchwood went defunct by 2010. What else are a bunch of people savvy to that business behind the curtain going to do?
* And by the same token, the Americans (and possibly many of the others) are veterans of the [[Franchise/StargateVerse Stargate Program]].

[[WMG: What S.C.O.P.E. Stands For]]

Since the game doesn't actually tell you what the device's acronym stands for lets take guesses. My guess is:

Sight Correction and Optical Perception Enhancer
* Shot Calculation to Optimise Performance Equipment
* Silly Contraption Only for Popping 'eads.
* Self-Computing Optical Precision Enhancement
* Self Correction OPtical eyepiece
* [[OverlyLongGag Some Creepy Old Pervert's Enabler]]
[[WMG: There's a reason for the recruits being terrible shots.]]

The XCOM recruits are supposed to be the best of the best, drawn from various military and special forces organizations from around the world. So why does it seem like they all graduated from the ImperialStormtrooperMarksmanshipAcademy? My hypothesis is that the guns are so large, heavy, unwieldy, use such a high caliber, and have such an enormous kick, that it takes a while for the troops to "get their eye in," so to speak. Even the basic assault rifle looks like it must fire a .50 cal BMG round, or something even more ridiculous, and that's before you get to the real exotic stuff like lasers or plasma.
** Not to mention the fact that, yes, they're the best of the best, but, well...they're fighting ALIENS. You're telling me THAT isn't going to make their hands shake a LITTLE?
*** On the rifles...the standard XCOM assault rifle (the X-9 I believe) has a MASSIVE barrel. Meaning, more than likely, its firing a huge round. .50 caliber perhaps...and as anyone who's seen the recoil from a Barret knows...well...

Now, why the XCOM HQ doesn't have a firing range for your troops to practice...
** This is actually a RealityIsUnrealistic moment. In real combat, the vast majority of shots miss.
** Hence the necessity for high rates of fire.

* alternatively, X-COM is a United Nations Operation. Which means the soldiers X-COM gets are not the best of the best so much as the absolute bottom of the barrel. This could explain a few other things, for instance why you get troops from all over the world, Why you can choose your base of operations from any continent on the planet, and why they use non-standard military ranks.

[[WMG: The Cult of Sirius will be an antagonist in XCOM: Enemy Within]]

In ''Enemy Within's'' [[http://www.youtube.com/watch?v=P4KdSli869U announcement trailer]] the Council Representative talks about "another force at work against us" before the feed cuts out. Very briefly [[https://fbcdn-sphotos-b-a.akamaihd.net/hphotos-ak-prn2/1237275_660151117342389_1118804672_o.jpg this]] symbol can be seen before the signal is lost.
* For those who don't know, the [[http://www.ufopaedia.org/index.php?title=Cult_of_Sirius Cult of Sirius]] was a human organization in the original XCOM that believed that the aliens were actually harmless and key to humanity's enlightenment. Ironically enough, as of ''Enemy Unknown'' [[spoiler:they might be ''right'', given the Etherial's motives to uplift humanity.]]
* A big clue here is the expansion's name: "Enemy Within". While [[WordofGod the developers have gone on record]] as saying the title comes using [[CyberneticsEatYourSoul cybernetics]] and [[GeneticEngineeringIsTheNewNuke gene splicing]] derived from alien technology is ''literally'' being the enemy within, it's very likely there's a dual meaning to the title.
* Expect to fight human soldiers similarly equipped to XCOM's own forces ''on top of'' the alien invasion itself, similar to the war against Cerberus and the Reapers in ''VideoGame/MassEffect3''. [[SarcasmMode Because a war of this scale on one front was already easy enough.]]
** Jossed: The player will not encounter both EXALT operatives ''and'' aliens during the single-player campaign, although in multiplayer they can build teams with units from all three factions.
* Partly confirmed; there's an alien sympathist faction called [[http://www.polygon.com/2013/10/9/4791464/xcom-enemy-within-exalt-2k-firaxis-anada-gupta EXALT]] that will try to undermine your operations, but they may or may not be related to the Cult of Sirius.

[[WMG: EXALT will be remnants of The Bureau having gone rogue.]]

While The Bureau: XCOM Declassified is an alternate continuity game to XCOM: Enemy Unknown, there's no evidence denying that The Bureau still existed in the XCOM: Enemy Unknown continuity, but never actually combated aliens, like in The Bureau. When it was believed that there was no threat, the Bureau was thought to have been disbanded, but in reality, they still continued to thrive and seek out alien technology due to the discovery of Elerium in the 1960s. Now that aliens are properly invading Earth, they have come out of hiding and are now seeking to gather all the alien technology for their own.
* Actually, it seems like The Bureau is part of the Enemy Unknown/Within universe...researching Meld in Enemy Within gives a small bit of flavor text referencing "redacted files on a similar substance" made in the '60s.
** ''Enemy within'' suggests otherwise about EXALT's origins, implying the organization is quite old and ritualistic, considering the age of the recovered artefacts from their HQ.
** Alternatively, EXALT is ''part'' of The Bureau's resources and personnel gone rogue, picked up by some other party and repurposed to suit their needs, while the majority of the Bureau became XCOM.

[[WMG: XCOM's Commander is [[spoiler:bonded with Asaru.]]]]

[[spoiler:At the end of The Bureau Asaru disappeared with "[[MythologyGag Its status, its location, and its intent are... unknown.]]" In a twist he never left Earth and once again acts as the player character to help against the invasion.]]
** In ''VideoGame/XCOM2'', [[spoiler: the Commander possesses extremely powerful psionic abilities after being downloaded into an Avatar body, and their psionic aura is the same light blue as Asaru's, instead of the deep purple used by psi troopers and Ethereals. The game explains all this as due to the Commander having had a microchip implanted into their brain that previously linked them into the alien psionic network, but the X-Com scientists explaining this may simply be misinformed. In the final mission, the Commander's Avatar seems to control their squad directly in the same manner that Asaru's host did throughout ''The Bureau''. And the game repeatedly mentions how special and incredible the Commander is, without providing any background details as to ''why'' they're the greatest tactical asset either side has ever seen.]]

[[WMG: XCOM:EU takes place in the same universe as {{TabletopGame/Warhammer40000}}]]
* The war against the Ethereals took place all the way back during the Age of Terra, with the the hostile first contact with alien life [[AbsoluteXenophobe forever cemented humanity's distrust of xenos]]. The reverse engineered alien technology jump stating humanity's scientific knowledge and allowing for rapid technological advancement that eventually became the basis for the Dark Age of Technology and the creation of the Standard Template Construct (with laser and plasma weapons being some of the few designs that survived into the 41st Millennium). While X-COM eventually inspiring Malcador to create the Inquisition (The organization's ability to serve as the guardians of humanity operating outside the law, and the Ordo Xenos inspired by [[JackBauerInterrogationTechnique Dr. Vahlen's alien interrogations]]) and the Emperor to create the Adeptus Astartes (A [[EliteArmy small, elite]], [[PoweredArmor power armor wearing]], [[{{Transhuman}} genetically engineered]], {{Super Soldier}}s that serves as the spear tip for the rest of the military during conflicts).
** The MEC troopers from ''Enemy Within'' are the earliest form of what would become Imperial Dreadnoughts after seeing how effective they were against the aliens, the use of giant cybersuits to allow injured soldiers to keep fighting became standard.
** It gets worse. The Mutons and Floaters (both made out of the same species)? The Krork (IE, progenitor race of the Orks). Spread far and wide across the galaxy, a few planets harbouring them were conquered by the Ethereals, which led to these groups being "uplifted". The extensive modifications seen on both enemies have dessicated them, turning their skin from healthy green to leathery brown. Their asexual spore-based reproduction system made them incredibly easy to breed and clone in large numbers, and their natural bloodlust makes them excellent frontline soldiers. Plus, Plasma makes gudd dakka.
*** Thin Men are heavily modified perversions of the Hrud, or possibly Slaan given their reptilian traits. Chryssalids are reverse-engineered from isolated Genestealer cults (or, again, the Hrud). Sectopods, Cyberdiscs and Drones are reverse engineered from Demiurg or possibly even Necron technology. There might not be an equivalent for the Sectoids, but its likely that they've been utterly exterminated and all knowledge of their existence lost by the time of the 41st Millennium.

[[WMG: What EXALT stands for]]
As with the S.C.O.P.E, the game never tells us what it means.
* A guess would be "'''EX'''tremist '''A'''lien-'''L'''oving '''T'''errorists".
* It stands for Exaltation, but X com assumes it's a acronym so they always spell it like EXALT.

[[WMG: As opposed to a BagOfSpilling]]
To justify developing new weapons and technology, the sequel will introduce SequelEscalation. The new aliens will be so heavily armed that even the technology from the first game is useless against them. This will likely be demonstrated by them destroying the base from ''Enemy Unknown''.
* Alternatively, in the sequel the player might control a different faction, which doesn't have XCOM's alien technology at the start.
* Sorta confirmed: XCOM got Curb-Stomped before they could make any significant research

[[WMG: EXALT will become a problem again in the sequel.]]
After the destruction of the Temple Ship, there's got to be an awful lot of aliens, alien artifacts (elerium, alloys, weapon fragments) and Meld lying around or flying around. EXALT is pretty much defeated, but if the aliens return, they'll have had a lot of time to mess around with quite a few resources, not to mention reverse-engineered XCOM designs. Enemy MEC units? OhCrap indeed.
** Potentially confirmed. The available news about the sequel seems to indicate there's a human force working with the aliens called ADVENT. Seems likely this is what EXALT turned into after XCOM was obliterated.

[[WMG: A future expansion pack will be focused on tracking the aliens to their source and finishing them off and/or on the greater threat the Ethereals were preparing for.]]
As a sub-WMG, it'll be named "Enemy Beyond" (could mean "enemy beyond the Earth", "enemy beyond morality", "enemy beyond comprehension", etc.). As for how the plot might go:
* The destruction of the Temple Ship left behind a portal in Earth's orbit. A recon mission reveals that it leads to the Ethereals' HQ. An assault mission is sent, with XCOM bringing along a strong psionic to hack into the Ethereals' information network/HiveMind to gather more intel. The gathered intel reveals the Ethereals are prepping for a greater threat and reveals the location of a member/unit from this greater threat separated from the rest. XCOM deploys there to gather more intel and/or try to secure an alliance, but finds out that they're hostile and stronger than anything previously encountered. XCOM defeats them with great difficulty, but is now left with [[SequelHook the prospect of battling an enemy even greater than the Ethereals]].
* Alternately, [[VideoGame/TheBureauXCOMDeclassified Asaru]] reveals himself and offers to help XCOM defeat his kin at the source. XCOM doesn't trust him at first, but accept his offer after his role in stopping the previous alien invasion is revealed. The rest continues as above, skipping the recon mission and the strong psionic requirement for the HQ Assault mission (since Asaru is tagging along). As a further CallBack, Zudjari survivors may show up and help XCOM against the Ethereals or the greater threat.

[[WMG: {{Series/ALF}} gets taken by XCOM.]]
One of Officer Bradford's soundfiles mentions that an "...alien craft crash landed in the garage of a suburban middle-class family... Tanner residence. Roger, we'll look into it." Now, consider how the ALF series ended...

[[WMG: The Ethereals aboard the Temple Ship were unable to 'Ascend' as the two Ethereals seen in The Bureau.]]
They appear to be less coporeal and less concerned with enslaving entire races, perfectly content to bond directly to people themselves instead of such. These failed Ethereals enslaved large numbers of Sectoids, Thin Men, and Mutons for their massive longterm experiment to ascend successfully. On top of that, the bonded Ethereals were able to grant powers never seen during the events of Enemy Unknown/Within, suggesting their psionics are better developed and more mature.

[[WMG: The Bigger Bad the Ethereals are preparing for are the Manifold Usurpers from Sid Meier's Alpha Centauri]]
* It's already been shown the Civilization franchise exists in the same universe as XCOM, and SMAC picks up where a Science Victory ends in Civilization. The Ethereals know the Usurpers are trying to achieve godhood through exploiting Manifold Six, and fear they will conquer all other races if not stopped. They've chosen to fight fire with fire and combat transcendence with psychic powers.

[[WMG: XCOM is commanded by [[VideoGame/CommandAndConquerRedAlert2 Yuri.]] ]]

An elite organization dedicated to specific strikes, which employs technology far beyond the scope of any other army, and eventually uses incredible psionic powers which manifest via [[PurpleIsPowerful purple]] energy? Sound familiar?

[[WMG: EXALT'S weapons going down with communication is satirizing always on DRM]]
Why would EXALT weapons need a "reload" action to be usable after you take down their communication network temporarily. Then I realized it works as [[TakeThat a jab at always on DRM.]] You lose the signal and it happens at the worst possible time in the middle of the action and need to restart. In this case apply it to the actual weapons. Bonus points: this inconveniences the users but never effects the people who actually steal it. Used by the very corporate EXALT despite the fact they should know better. DoesThisRemindYouOfAnything?

[[WMG: "What lies ahead" will be explained in the upcoming Beyond Earth.]]
Or what lies ahead is Beyond Earth. The Ethereals were preparing us to go Beyond Earth. If the "Ascension" Victory Option from Alpha Centauri makes a return, then the new Ascension will be performing what the Ethereals themselves failed to do. Considering that X-COM squads make an appearance in BNW...
* What XCOM refers to as "Meld" is actually the Firaxite that allows for the BrainUploading of Supremacist civilizations, and Purist factions believe they are following in the footsteps of the XCOM project.

[[WMG: William Thorne was in league with EXALT.]]
He wasn't colluding with the aliens, he was colluding with the group that was colluding with the aliens. XCOM simply got a few details wrong with their intel.

[[WMG: The Sectoids are actually sociopathic murderers.]]
Taking from the WordOfGod that Sectoids are intrinsically cruel and cowardly and that they're actually clones of the same individual Sectoid, it is very likely the Etherals merely chose a single Sectoid who had the gift and either did not know about its murderous tendencies after they starting clones it and/or purposely chose it [[AssholeVictim to make it suffer as a one man disposable army]]. Either way, the Sectoids seen in the game may not be actually indictive of the species as a whole.

[[WMG: The 2012 remake that Firaxis is [[CelebrityParadox famous for in the XCOM:EU universe]] is ''VideoGame/SidMeiersAlphaCentauri 2'']]
Both ''VideoGame/{{X-COM}}'' and ''VideoGame/SidMeiersAlphaCentauri'' are highly beloved classics without a worthy successor until Firaxis stepped in, this happening for the former in our universe, and for the latter in XCOM:EU's.

[[WMG: The secretive 'XCOM War' sets the stage for the United [=EarthGov=] in Series/BabylonFive]]
Literally everything except the canon sets the stage for this. Forced Evolution, resulting in Telepaths. A Secret 'Greater Enemy' Humanity is being groomed to confront, Earth's sudden rise to Prominence in the Dilgar War and the utter shock at actually *failing* to defeat an Alien Invasion during the Minbari War. A Sectoid eventually gets Sued.

Really, the only question is whether the Ethereals were grooming Humanity to fight the Shadows, or given the 'Forced to Evolve' nature of the invasion, to fight the Vorlons.

[[WMG: XCOM and The Sims inhabit the same universe]]
The symbol for credits is the same symbol as used in The Sims for Simoleons. XCOM uses Simoleons.


[[WMG: All the covert operative send against EXALT could gather is random chatter and banter between random technicians in EXALT's HQ.]]

It is common for people working long job watching evolving data on screen and communication through radio to banter with each other to kill some time. And that banter is the only thing the Covert Operative could pick up. The Covert Operative has confirmed that the banter comes from the EXALT HQ, but couldn't locate it. How would banter help locate the HQ you ask?

"Really, the dub for Anime/SailorMoon is a [[BlindIdiotTranslation train wreck]]. Bad acting, censorship, continuity errors, you name it! I'm glad I downloaded the subbed version. Say, I'll drive you to the restaurant after our shift, okay?" The technician at EXALT's HQ lives within driving distance of it, and doesn't speak Japanese (why else would he need to download a subbed version of a Japanese anime after watching a dub he called a train wreck?) Therefore, the EXALT's HQ is not located in Japan.

"The good thing about working this job is that it's well paid and in my home town, therefore I can go to my favorite sushi restaurant any time I want. The bad thing is that I had to go through annoying English classes just to get it." Any people born in an English speaking country like the UK, Canada, the USA or Australia would have already learned English long before taking a job at EXALT. The EXALT HQ is not in an English speaking country.

"You know what? I'd like to visit Brazil one day. I heard it's a pretty nice country that's very accepting of gays like me." The EXALT HQ is not in Brazil.

[[WMG: The scientists aren't OmnidisciplinaryScientist.]]

Simply, each scientist knows some basics on every scientific field and basic experiment standard operating procedures, and has a pretty good understanding of mathematics and computer use. On each project, the experts device experiments to understand thing, the non experts help set up the system, and after it has been performed, the lead scientists in the project give the ones not expert in the field relevant, boring, repetitive but easy calculations and computer work while they do the more interesting and specific stuff. But the ones doing the boring stuff know that when the next experiment is withing their field of study, the roles will be reversed, possibly leading to banter such as "I will have my revenge on you someday!" during experiments.

[[WMG: X-com created the Ghost Program.]]

Psi snipers + Ghost Armor/Mimetic Skin = Ghost
Aside from the ghost armor your snipers can't call nukes though

[[WMG: The aliens are humans from alternate futures.]]

Humankind encountered some terrible threat beyond mortal comprehension, and to fight it, they develop the latent psychic abilities of certain rare individuals, performing one extreme experiment after another. The result was...the Ethereals. They failed, but just before the "greater threat" destroyed the Earth (or something), they were able to time travel back to a point well before the Greater Threat's emergence.

They then invaded the Earth of their past, the denizens of which assuming they were from another planet, in order to abduct more specimens to genetically and cybernetically enhance, and wound up with the Sectoids, who, again, failed to stop the threat. So the Ethereals went back in time again. Next came the Thin Men, then the Floaters, then the Mutons, and perhaps even the Chryssalids. Again and again their creations failed. The game takes place on the final cycle, when the Ethereals finally realize that HumansAreSpecial, letting them develop psionic powers themselves, and finally end up with the ideal psionic specimen.

[[WMG: The Triad Zhang deflected from is part of E.X.A.L.T.]]

That's why Zhang deflected, he realized that trying to TakeOverTheWorld during an AlienInvasion wasn't a good idea.

[[WMG: The X-COM Project is real]]

Think about it, read any old UFO story where the military miraculously shows up moments after a UFO crash. The whole point of the original X-COM's creation was to make the whole thing seem to be absurd and with the massive increase in tech they revived the propaganda campaign to basically make anyone reporting strange soldiers showing up at UFO crashes seem like kook talk.

[[WMG: The whole game is a StableTimeLoop.]]

Final mission, [[spoiler: the most powerful Psionic on Earth, possibly in the universe, sacrifices themselves to save the planet from the exploding alien ship. WordOfGod says this doesn't kill them. They instead AscendtToAHigherPlaneOfExistence, becoming some sort of omnipresent force. Eons before the game, the aliens detect this force, but have no idea what it is, just that the universe needs to be ready to fight it.]] They build an army, research psionics, and invade Earth.

If they succeed, [[spoiler: the final mission never happens, so the Volunteer never sacrifices themselves]], undoing the StableTimeLoop and resulting in X Com 2.
