Deus Ex: Human Revolution

Plot synopsis:
=== Setting ===
Human Revolution takes place in the year 2027, 25 years prior to the original Deus Ex. The Deus Ex series is set in a cyberpunk future rife with secret organizations and conspiracies: among these forces is the Illuminati. Leading up to Human Revolution, there have been marked improvements in human society, with people actively combating global warming, finding cures for a large variety of diseases, and improving green energy. Alongside this, global megacorporations have come to eclipse government authority in power and influence, while private military forces dwarf the sanctioned armies of First World countries. Advances in biotechnology and cybernetics have led to the development of "augmentations", advanced artificial organs capable of greatly improving and enhancing the human body's performance. The development of augmentation technology has triggered the creation of a new social divide: those with augmentations become the world's new upper class citizenry and are touted as the future of humanity, while normal humans form the majority of the lower-class population. Augmentations also come with the necessity of taking Neuropozyne, a limited and expensive immunosuppressive drug that stops the body rejecting the technology. By the events of Human Revolution, society is being divided between "augs", humans who have accepted augmentation technology; and normal humans who are either morally opposed to it, too poor to afford it, or whose bodies actively reject it. The tensions between the two factions begin generating open conflict.
=== Characters ===
The main protagonist is Adam Jensen: coming from a humble background in Detroit, he worked as a leader with the local SWAT squad until he refuses to follow a questionable order and is turfed out. After this, he is taken on as security manager at Sarif Industries, a local company at the leading edge of augmentation technology. A fellow at the company is Megan Reed, a researcher for Sarif and Adam's ex-girlfriend. His employer is company CEO David Sarif, who is instrumental in saving Adam after he was left near-dead at the beginning of the game. Adam meets many key characters during his missions between Detroit, Montreal and the new Shanghai metropolis of Hengsha. These include Sarif's chief pilot Faridah Malik; Sarif systems engineer Frank Pritchard; Eliza Cassan, a media personality and public face of Picus Communications; William Taggart, founder of the anti-augmentation group Humanity Front; Hugh Darrow, who founded augmentation technology but is one of those genetically incapable of using them; Zhao Yun Ru, CEO of the Tai Yong Medical megacorporation; and the "Tyrants" mercenary squad, composed of leader Jaron Namir and his associates Lawrence Barrett and Yelena Fedorova.
=== Plot ===
Note: While the general plot of Human Revolution follows a distinct path, many elements are subject to the player's decisions. The game also offers several subplots which the player may or may not encounter, depending on their actions within the game. This synopsis concentrates on the main, unavoidable plot thread of the game.
On the eve of unveiling a new type of augmentation that will negate the use of Neuropozyne, Sarif Industries is attacked by the Tyrants. Adam Jensen attempts to save Megan Reed and her fellow scientists, but Tyrant leader Namir critically wounds him and apparently kills Megan and the scientists. David Sarif uses his most advanced technology to save Adam, giving him superhuman abilities: he also learns that the augmentations are bonding to him naturally without the need for Neuropozyne. Called back to deal with an attack on a Sarif Industries warehouse by anti-augmentation extremists, Adam discovers an augmented hacker attempting to gain access to the secret Typhoon weapon augmentation. Upon discovery, the hacker is forced by their controller to shoot himself. After Adam retrieves the deceased hacker's neural hub from his old Detroit police precinct, Frank Pritchard tracks the hacking signal to an abandoned factory in Highland Park. Adam discovers the Tyrants guarding a FEMA detention camp, but they are moving out after the failure of the Sarif raid. Adam confronts and defeats one of the mercenaries, Barrett, who tells him to go to Hengsha before killing himself with a grenade.
Together with pilot Faridah Malik, Adam travels to Hengsha and tracks down the hacker, Arie van Bruggen, who is being both hunted by private security company Belltower Associates and hidden by local triad leader Tong Si Hung. Van Bruggen directs Adam to find evidence inside Tai Yong Medical, the world's largest augmentation technology manufacturer and Sarif's main rival. Infiltrating Tai Yong, Adam finds footage of a call between Namir and Zhao Yun Ru, which confirms that Megan and the other missing scientists are alive and that Eliza Cassan is somehow involved. Confronting Zhao in her penthouse apartment, he learns that she is allied to a powerful organization that controls global interests before she triggers security and forces him to leave. Traveling to the Picus corporate building in Montreal, Jensen tracks down Eliza, revealed to be an artificial intelligence construct designed to influence the media: despite her programming, she has begun to question her role, and offers to help Adam. After he defeats Tyrant member Fedorova, Eliza gives him footage directing him to Doctor Isaias Sandoval, aide to William Taggart.
Back in Detroit, Sarif admits to Adam that the Illuminati are behind the attacks. Adam infiltrates a Humanity Front rally and discovers Sandoval's location. Sandoval admits his involvement in the kidnapping and gives Adam the lead to find the researchers. Back in Sarif HQ, Adam meets Hugh Darrow, who is currently working to stave off global warming with the newly constructed Panchaea Facility in the Arctic. Adam, along with other augmented people, also start experiencing painful glitches, with authorities urging them to have a biochip replacement. Pritchard locates the tracking beacon of one of the scientists, taking Adam back to Hengsha, where he and Malik are ambushed by Belltower. The beacon leads Adam to Tong Si Hung, who has just been implanted with the now-deceased scientist's arm. Under Tong's direction, Adam manages to stow away in a stasis pod in the wake of a staged explosion, waking up a few days later in a secret Singapore base. He finds the kidnapped scientists, and learns that the biochip malfunctions were staged to distribute the result of their research: a new biochip to control augmented humans. Adam and the scientists stage a distraction, allowing him to infiltrate the facility's secret bunker. Here he faces Namir one last time, then finds Megan. Confronted, Megan tells him that she was kidnapped for her research; the genetic key to make all humans compatible with augmentations, which she found in Adam's DNA — and to help Darrow foil the Illuminati's plans.
Moments later, Darrow appears live on television and broadcasts a modified signal that throws any augmented person with the new biochip into a fear-driven, murderous frenzy. Jensen evacuates the scientists, and commandeers an orbital flight module to reach Panchaea. He confronts Darrow, who reveals that he wants humanity to abandon the augmentation technology he invented, because he believes it will destroy human identity. Adam sets out to disable Panchaea's supercomputer and end the broadcast; on the way, he encounters Taggart and Sarif, who each urge him to side with them and further their own agendas. At the heart of Panchaea, Jensen first confronts Zhao Yun Ru when she tries to hijack the signal for her own use; then Eliza, who offers Jensen four choices. Jensen can either broadcast the full truth and distance humanity from augmentations; rig the broadcast so it throws suspicion on the Humanity Front and allows further development of augmentation technology; send out a report blaming the incident on contaminated Neuropozyne so Taggart's group and by extension the Illuminati find new support; or destroy Panchea, leaving no-one to "spin the story". Depending on the choice and whether Jensen has taken a pacifist or violent approach through the game, his final narration varies.
In a post-credits scene, Megan meets with Bob Page, the main antagonist of Deus Ex, and discusses her employment in "the nanite virus chimera" and "D project": prior to this, Page instructs his cohort Morgan Everett to search the Hyron Project wreckage for salvageable technology for the 'Morpheus Initiative': these are the precursors to the manufactured nanotechnological "Gray Death" virus and the "Helios" artificial intelligence, key parts of the plot of Deus Ex.
