History Trivia / DeusExHumanRevolution

** The "neo-Renaissance" was also supposed to have a greater influence in fashion leading to concept sketches like [[http://www.incgamers.com/images/screenshots/27691orig.jpg these.]] [[TropesAreNotBad This was arguably for the better.]] (unless Jensen wore an [[Franchise/AssassinsCreed Assassin hood]])

* OldShame: Elias Toufexis, Adam's voice actor, claimed that he's embarrassed about some of the early recordings before he'd gotten a handle on Jensen's accent and speaking patterns, such as the conversation with Haas (which at certain points almost doesn't sound like Jensen at all). His explanation for the fluctuations is that the voice recording process took place over the course of two years and the resulting mix was between recent and old material.

** The Tai Yong Medical building was originally supposed to be arranged as a vertical factory, with a long shaft following the entire building and robotic production lines following the entire height of the building.

* ApprovalOfGod: Warren Spector, the man behind the original game [[https://www.google.com/amp/s/www.vg247.com/2018/11/12/deus-ex-3-warren-spector/amp/ had only a few issues with the game]], [[note]]The cover system, no free startup weapon, enemies taking too long to reset after failed stealth, and surprise surprise, the boss battles.[[/note]] and he considered the game a good addition to the series.

* RelationshipVoiceActor: The voice actors for Adam and Megan are married.

** As well as Motoko Kusanagi of Franchise/GhostInTheShell, whose VA Creator/AtsukoTanaka voices the BigBad of the game.

* PromotedFanboy: Will Rossellini, the game's technical consulting for medicine and prosthetic, got the job because he reached out to Eidos saying how much his expertise could help the writing team, and because he was a huge fan of the original ''VideoGame/DeusEx''. The writing team in turn made him one of the employees in the Sariff offices, since he works in that field he would be present playing a CharacterAsHimself. He thought this was awesome.

* NoExportForYou: The Collector's Edition is Exclusive to Europe.

** They also stated that the lack of development time was the reason why [[spoiler:the game's ending is literally chosen via button presses]] as opposed to something more involved. The endings themselves however, were exactly what they intended.

*** YMMV on that: the middle three at least would fit in quite well.

** The Ty Yong Medical building was originally supposed to be arranged as a vertical factory, with a long shaft following the entire building and robotic production lines following the entire height of the building.

* HeyItsThatVoice: [[VideoGame/SplinterCell Andriy Kobin]] and [[VideoGame/AssassinsCreedII Federico Auditore]] never asked for this.
** Neither did [[Creator/HirokiYasumoto Sado]] who gets pestered by [[Creator/JunichiSuwabe Grimmingjow as mission control]] with [[Creator/AkenoWatanabe Ibis]] flying the VTOL. It also seems that !Japanese Sarif is [[Creator/ShuichiIkeda a CHAR]], meanwhile [[Creator/YukoKaida Veronica/Marida]] has been augmented with technology developed by [[Creator/KiyoshiKobayashi Argille Delaz]]. [[MotomuKiyokawa Tem Ray]], being a Feddie is opposed to augmentations. Apparently, [[AtsukoTanaka Mokoto Kusanagi]] is the CEO of Tai Young Medical.
** Elias Toufexis is also known for doing a lot of narration work on commercials for companies like [[https://www.youtube.com/watch?v=mqAZqfkSniI Lexus]] and [[https://www.youtube.com/watch?v=Fc4nAJ130aM the Yellow Pages]].
** Though it's incredibly brief, [[VideoGame/SplinterCell Irving Lambert]]'s voice appears during the ScenicTourLevel at the beginning (as the General talking to Sevchenko about the Typhoon augment).
** Bill Taggart is WesternAnimation/{{Arthur}}'s dad and Binky Barnes.
*** Hugh Darrow is Mr. Ratburn.
*** Oliver Frensky voices some of the police officers at the Detroit police station.
*** Francine voices several nameless [=NPCs=]. A few more [=VAs=], and this game could have been an ''Arthur'' reunion.

* HeyItsThatVoice: [[SplinterCell Andriy Kobin]] and [[VideoGame/AssassinsCreedII Federico Auditore]] never asked for this.

* ExecutiveMeddling: The reason why ''The Missing Link'' was DLC added later (rather than part of the core game, as originally intended) is because the game was rushed after being delayed repeatedly. This is the same explanation for the why the Tyrant boss battles are more "head-on" than series fans would've liked, since they were farmed out to third-party developers to save time during production (Which is also why two hub areas- Montreal and Upper Hengsha- were abandonced).

* CallForward: Oh so very many. Just to name a few:
** A street preacher in Detroit will mention bad things to come that are "grey and deadly", and a mention of 12 kings. The Grey Death was a pandemic in the original game, and the organization that was fought against was Majestic 12.
** The game begins with a look at a statue, followed by [[spoiler:Bob Page]] engaging in conspiratorial conversation.
** An e-book in an apartment predicts the rise of [[{{Nanomachines}} nano-augmentation]] in roughly thirty years. (''HR'' is set in 2027, the original was set in 2052.) In the convention center, advertisements can be seen regarding the development of nanoaugmentation.
** An email from a paranoid woman saying how a certain Philip Mead is trying to get votes in a major election. [[ProperlyParanoid Guess who's in the White House in the original game?]]
** A secession group called the New Sons of Freedom, or the [=NSF=].
*** In the original Deus Ex, NSF stood for National Secessionist Front.
**** It had already been through one name change and kept the initials.
** It is possible for your pilot [[spoiler: to die in the game.]]
** There is a character in both the original and ''HR'' who [[spoiler: will be under attack, and will tell you to save yourself. You can listen to them, and they'll end up dying, or you can stay behind to save their life.]]
** An [=NPC=] will question your decision on wearing sunglasses out at night.
** [[spoiler:Joseph Manderley is responsible for covering up key evidence from the Sarif attack and the Milwaukee incident.]]
** Versalife is a manufacturer of the drug neuropozyne. They're also stated to be working on nanotechnology for medicinal purposes.
** Page Industries is mentioned.
** One of the researchers at [[spoiler: Omega Ranch]] says in an email that he's started naming [[spoiler: the babies they're genetically modifying to accept nano-augmentation after the apostles... Paul?]]
** Several emails written by people with cyberlimbs, including powerful, well-educated people, are riddled with typos (much like Gunther's similarly misspelled emails from the first game) , the implication being a lack of feedback, or simple inexperience with augmented limbs, when it comes to finer tasks such as typing.
** FEMA is being used for shady activities.
** When Marik takes off from the Detroit factory the camera movement is identical to how Jock's helicopter takes off.
** A tidbit of news seen on the TV will mention the sales of orange and lemon-lime soda.
** A security guard at Tai Yong Medical will mention how another guard joked about getting the wrong soda from a vending machine.
** A few notes from the Sarif Office theme in the prologue mission is from the [=UNATCO=] music. Example [[http://www.youtube.com/watch?v=iCGBzrpxpsU&feature=player_embedded here]] (Starts around 2:20.)
** There is mention of "Germans" working on a Skull-gun and gun enthusiasts' magazine carries an article titled "Skull Guns and Other Implanted Weaponry".
** A newspaper article mentions plans to create a special UN branch to combat growing international terrorism.
** The keycode for David Sarif's private elevator is 0451, which was also the keycode for the UNATCO storage shed, and continues the tradition it inherited from the SystemShock duology of (0)451 being the first numerical keycode you have to enter in the game.
** The area surrounding the hero's workplace starts out under attack, with hostages involved.
** For the first real mission, the hero is asked which weapon he would prefer, each weapon supporting a different playstyle.
** People are smuggling things out of the hero's workplace.
** The first large area is a city in the USA with a very run-down slum that Adam has to go through, complete with big sewers and a lot of diseased bums. The enemies in this area put explosives at strategic points and have people on rooftops. There is a storage area that can be broken into, and [[spoiler:a secret underground government base nearby]].
*** And one of the gun smugglers you can find in the area is black and wearing a hoodie and sunglasses. The rescue of someone leads to him giving a discount.
** The second large area is a city off the coast of China, where the protagonist must go to a nightclub and contact someone with ties to TheTriadsAndTheTongs, as well as investigate a specific floor of a penthouse. [[spoiler: The hero must also infiltrate a bio-corporation and comes into conflict with a DragonLady.]]
*** In this Chinese city, there is an optional conversation about the corruption of Western governments.
** At some point, you will visit a major city where many people speak French. [[spoiler: This French-speaking city is where the hero starts to really converse with AI.]]
** A detective will greet you with a "in the flesh."
** [[spoiler: In Montreal you visit a secret underground lair that contains both the Illuminati logo on a hallway as well as a statue of the MJ-12 logo.]]
** [[spoiler: Morgan Everett is the CEO of Picus TV and Elizabeth [=DuClare=] is a spokeswoman for the World Health Organization.]]
*** [[spoiler: Lucius [=DeBeers=] is also apparently pestering Sarif to join the Illuminati to the point where Sarif has left explicit instructions for his secretary to ignore his calls, and [[WildMassGuessing he may also be one of the people Page talks to in the opening cinematic]]]]
** Two of the achievements are named "Cloak & Daggers" and "Smash the State," the first of which was a passphrase and the latter of which was an NSF password.
** [[spoiler:Tong's son is seen boarding a ship named "The Tracer," and his intention is to go to Hong Kong. It's Tracer Tong.]]
*** [[spoiler:Adam also gives Tong Junior a bit of advice that he promises to remember. It's a paraphrase of a line in the first game.]]
** [[spoiler: The "Taggert's Message" ending shows Adam walking into an office with a man who looks a lot like Joseph Manderley, suggesting he becomes the first UNATCO agent.]]
** [[spoiler:The biochip is a clear precursor to the mech-aug killphrases and the nano-aug killswitches]]
** [[spoiler:The basis of the conspiracy is to give people an affliction so that they will become dependent on a product which the conspiracy conveniently provides.]]
** [[spoiler: When Taggart and Sarif give their requests to Jensen on what to broadcast, just before leaving them, Jensen simply says, "I'll think about it," just like JC would 25 years later in Area 51.]]
** A subtle one, there is an area in Hengsha that closely resembles the canal area in Wan Chai, even down to two police men standing off to one side, one warning the player that tourists better watch out away from the main areas, and the other not speaking English. Possibly not intended.
** One of the items in the news ticker mentions a film named [[VideoGame/DeusExInvisibleWar Invisible War]] shattering box office records.
** "The Missing Link" features [[spoiler:a young Gary Savage involved with the Hyron Project.]]
** Near-miss: [[http://www.youtube.com/watch?v=ef-e025FlPY "That's a shame."]]
** Scoring a hoop on a basketball court in a rough area of town earns the player some secret congratulations.
** A Dr. Jankowski works in the LIMB clinic in Detroit.
** An unseen worker on Panchea is named [=JC=].
** At the end of the game, [[spoiler: talking to Taggart will have him mention that supporting him will eventually lead to a reorganized UN that would be able to combat issues such as terrorism. This could be a possible hint that Taggart's ending is the canon one.]]
** If you keep talking to the guard that first mentions death by vending machine, [[http://www.youtube.com/watch?v=sx1Q4L6lOc8 he will go on to talk about someone who gets wrong-flavour soda.]]
** A subtle moment in Montreal has you walking up to a globe being held by a hand, with the corridor and room you enter into being quite reminiscent of the room originally seen in the introduction to {{VideoGame/Deus Ex}}.

** Neither did [[HirokiYasumoto Sado]] who gets pestered by [[Creator/JunichiSuwabe Grimmingjow as mission control]] with [[Creator/AkenoWatanabe Ibis]] flying the VTOL. It also seems that !Japanese Sarif is [[Creator/ShuichiIkeda a CHAR]], meanwhile [[Creator/YukoKaida Veronica/Marida]] has been augmented with technology developed by [[Creator/KiyoshiKobayashi Argille Delaz]]. [[MotomuKiyokawa Tem Ray]], being a Feddie is opposed to augmentations. Apparently, [[AtsukoTanaka Mokoto Kusanagi]] is the CEO of Tai Young Medical.

** You were originally supposed to be able to [[spoiler:spare Fedorova and Namir]] after defeating them.

** The Director's Cut reveals that Malik was originally intended to be Arabic and use Arabic swear words- while her VA could pronounce them right, the developers weren't happy and decided to change Malik into an American.
