Adam climbs out of the crashed shuttle and swims over to the dock at Panchaea.
Pritchard calls to explain that the signal is still broadcasting and there's been no word from Sarif, Taggart or any of the delegates. He tells Adam to head to the top of the nearby tower and disable a lockdown before the signal can be shut off at the base of the station.
The agent continues through the facility, passing many dead bodies on the way. He eventually reaches the top of the tower. Before he disables the signal, Darrow reveals that he is still alive in the room and says that disabling the lockdown will cause the crazed civilians to run rampant on the platform. He tells Adam that he regretted his invention of augmentation technology and activated the signal to convince the world that it wasn't the future of humanity. He then explains that activating the signal also thwarted the Illuminati's plan of controlling augmented people.
A social battle ensues between the two. It eventually results in Darrow revealing that he was jealous of other augments because he couldn't use the technology himself. Darrow realizes that Adam is right, and gives him the command codes to shut down the signal at the broadcast station in the base of the facility. He warns the agent that the platform's security system is still active and very lethal.
Adam turns off the lockdown and heads towards the platform's blast doors. He passes several crazed civilians on the way and eventually reaches a blocked-off server room with Taggart and his support staff. Taggart rails at Darrow for betraying the conspirators, who Adam realizes he was a part of.
Taggart ensures Adam that he only wanted to regulate augmentation, and calls on him to broadcast a signal explaining that the world's neuropyzyne supply was tainted, which caused the accident. He ensures Adam that he can create a future that is regulated and not overseen by the conspirators.
Adam continues on and eventually finds another blocked-off room where Sarif and other civilians are hiding. Sarif expresses relief at Adam's arrival and tells him that they have to evacuate the survivors first. Sarif tries to justify his stance by claiming that humanity will outlaw augmentation technology if they find out the truth of what's happened. He tells Adam that they should send out a signal that Humanity Front caused the incident. Adam says that he'll think about it.
Adam continues on and uses an elevator to reach the base of the platform. He finds the security command room and enters.
Several women are strapped to a machine in the center of the room and are spouting technological language. Zhao suddenly appears behind a window and reveals that she intends to connect herself with the security system, which is referred to as "the Hyron Project". She explains that the project uses human brainpower to run an advanced series of quantum computers. She then tells him that she's going to use the computer to send out a signal promoting the Illuminati's agenda. The machine connects to her back and lifts her into the air.
Adam fires a shot at the window, but it ricochets off the glass and the security system activates. He quickly shuts it down by hacking the control panels surrounding the female occupants in the machine. The machine overloads and destroys Zhao in a large explosion.
He continues through a tunnel behind the control machine and reaches the broadcast room. Eliza Cassan greets him and says that she accessed the station before Darrow activated the signal.
Adam tells her that he has to stop the broadcast, and she explains that the future of humanity lies in the balance. She tells him that he can either send Darrow's signal (reveal the truth about the biochip signal the the Illuminati, causing humanity to fear augs), Sarif's signal (blame Humanity Front for the attack and allow corporations to take control of augmentation technology) or Taggart's signal (lie about the signal and place harsher restrictions on augmentation research).
The agent is faced with a difficult choice...
In a voiceover, Adam explains that Sarif was right about humanity being compelled to rise above its limits. He says that the future depends on how humanity approaches it, and that Sarif's path will allow them to keep their values and morality in check. He then states that humanity should keep pursuing technology and hopes the dream of "becoming gods" will be worth it...
Adam is heard in a voiceover explaining Taggart's vision of regulating augmentation technology. He muses over the notion of freedom and how it will impact humanity. He eventually admits that unchecked power has led to countless conflicts, and says that he managed to hang onto his humanity in spite of temptation. He then says that Taggart was afraid of the chaos, and agrees that humanity's eventual leaders will rise to the challenge...
Adam explains in a voiceover that he finally understands a point Albert Einstein made about technological progress being like an axe in the hands of a criminal. He admits that technology has negatively impacted life more often than it has helped, and that augmentations are a dangerous tool. He then states that Darrow understood the gravity of the situation and that his confession can be a seed for change...
Eliza reveals that there is a pressure regulator nearby that will cause the installation to destroy itself and kill everyone onboard. When Adam asks what it will accomplish, she says that the world will have to decide for itself what happened. Adam walks to the regulator and presses the button. Eliza tells him that there is little time left, and that It Has Been an Honor talking to him. The platform is heard breaking apart...
In a voiceover, Adam wonders if humanity can be trusted to save itself. He admits that he doesn't know, but hopes that human decency will triumph.
Bob Page is heard on a phone call telling Morgan Everett to continue searching through wreckage to salvage something for the Morpheus Initiative. He hangs up and is introduced to Megan, who has been summoned to his office. She says that Page Industries was the only place she could find work at, and Page tells her that they have many projects that will be of interest to her. She expresses interest on working on a new virus, and Page tells her to "call him Bob".
- Alignment-Based Endings: Dialogue in the chosen ending changes based on whether Adam killed or knocked out enemies, and if he was helpful towards others throughout the missions.
- And I Must Scream: The three women who power Hyron are constantly crying for help, unable to perceive anything except for their calculations and confinement. One regains her lucidity just long enough to give Adam some crucial advice before lapsing back into blind terror.
- Body Horror:
- The converted civilians who had the biochip upgrade, and shamble around like zombies.
- The women in the core are attached to Hyron by their spinal columns and suspended head-down with their hands and feet shackled. They are also blindfolded.
- When Sarif and Taggart give their requests to Adam on what to broadcast, he acknowledges them with a simple "I'll think about it", just like JC said in the original game when Everett, Tong and Helios outlined their respective proposals.
- The Stinger begins with Page having a conversation with Everett about continuing to dig through the wreckage on Panchaea and ending with Megan expressing interest in development of a virus that will presumably become the Gray Death in the original game.
- The Cobbler's Children Have No Shoes: If the right CASIE options are taken, it is revealed that Darrow (the man who created augs in the first place) can't use them on himself.
- Cores-and-Turrets Boss: The Hyron core.
- Cutting the Knot: The final boss fight can be trivialized by pulling out the laser rifle and shooting Zhao through the bulletproof glass,
- Evil Is Petty: Darrow is rather pissed and bitter his own invention can't do a thing for him, so he hijacked the Illuminati's plans and tweaked them so he can make sure the whole world gets to know just how much he's come to hate his own creation.
- Femme Fatale: Megan becomes this in The Stinger, no matter which ending is chosen. She willingly goes to Bob Page (and brings Adam's DNA samples, to boot) and expresses interest in helping to work on a virus...
- Foregone Conclusion: No matter what choice Adam makes, the world still spirals into a worse situation in the next twenty years and the Gray Death virus is still developed.
- Fun with Acronyms: The "Hi-NRG" Plasma Rifle, which is only found in the final mission.
- Greater Need Than Mine: Sarif is more concerned with evacuating the unaffected civilians than himself when Adam finds them holed up in the lower levels.
- Handicapped Badass: Darrow's cane is covered in blood when you find him, implying that he beat at least one of the crazed civilians to death with it.
- Hate Plague: Darrow does this by activating a signal that causes all augments to go into a murderous rage and kill anything in their path.
- The Hero Dies: If the "Self-Destruct" ending is chosen.
- Human Resources: The Hyron Project.
- I Did What I Had to Do: Darrow says this verbatim while justifying why he activated the signal.
- It Has Been an Honor: Eliza says this to Adam verbatim if the "Self-Destruct" ending is chosen.
- Kill 'Em All: The "Self-Destruct" ending, which kills everyone still alive on Panchaea and lets humanity decide for itself what happened there.
- Merging the Branches: All of the endings could plausibly lead to the events in the original game.
- My God, What Have I Done??: Hugh Darrow has this moment if you use the Social Enhancer to uncover that he actually staged the mass insanity of augmented people because he, as the creator of the augmentation technology, is one of the few people genetically incompatible with it and grew jealous of others over time. It is also implied that he had a moment like this in the background when he created Hyron, as he pretty much outright says that Hyron is an example of what horrors human augmentation technology will inflict.
- My Greatest Failure: Darrow takes this view about his invention of augmentation technology.
- No Hero Discount: Adam is still forced to pay full price from the Dungeon Shop, even when everyone else in the immediate area (besides the shopkeeper) is crazed. The game justifies this by having the shopkeeper claim she can't change the prices because they're hardcoded into the computer.
- Nothing Is Scarier: The entire sequence from when the player first arrives to the confrontation with Darrow is devoid of enemies, and many bodies laying in the halls.
- Not So Different: Darrow suggests that Adam and himself are they same because they know how to sacrifice lives for the greater good. Adam shoots that argument down by pointing out that what Darrow is doing is genocide on a large scale.
- Screw the Rules, I'm Doing What's Right!: The three main endings have Adam state this, more or less. Subverted by the fourth ending, where Adam says that he doesn't have the right to decide what's best for humanity, and will let them make the choice themselves.
- "Shaggy Dog" Story: Adam's quest to rescue Megan is ultimately pointless, as she doesn't bother to get back together with him (assuming that he lived) and instead chooses to work for Page Industries — taking along Adam's cell samples as well — to work on the virus.
- Technically Living Zombie: The infected civilians on Panchaea are people who've gone insane due to Darrow's signal.
- The Stinger: The Page/Reed conversation.
- Take a Third Option: The "Panchaea destruction" ending.
- Unexpected Gameplay Change: The majority of the mission involves the player fighting "zombified" humans who have been altered as a result of Darrow's machinations.
