Prologue
The year is 2020.

The prologue sees Joanna Dark in a DeathMatch VR simulation. Joanna infiltrates the Trinity Research Platform, bypassing several layers of security before reaching the platform's CPU. She destroys the CPU by piloting a CamSpy into its proximity and detonating its explosive ordnance. The destruction of the CPU causes the spiderbots on platform to become uncontrollable and they begin to attack the personnel. Joanna makes her way to a lift which takes her to the surface. A large security force ambushes her as she regroups with her father, Jack Dark. They manage to fight their way to a rocket before the simulation is terminated.

Hong Kong
Dark Bail Bonds is after a scientist named Nathan Zeigler. The Dark Team has been tracking him for months, and now he has wound up in the hands of the Hong Kong Triad gang, led by a man named Killian. He's about to be exchanged for a large reward, but the Darks are to recover him before the trade can happen. The plan was for Jack to gain access to the Hong Kong nightclub, where Zeigler was being held, while Joanna hung back to support him. She is inserted by Chandra Sekhar via speedboat on a dock. Jack gets caught up in a firefight in the club, and Joanna quickly moves into the club to assist him. She battles her way through the nightclub, eliminating several of Killian's thugs as she moves to the upper levels. Meanwhile, Jack confronts Killian in his office. Joanna arrives and Jack's guard is thrown and Killian escapes, shooting Jack in the shoulder before throwing himself out a window.

Zeigler refuses to go anywhere without his research documents, and Joanna is sent to recover them. She moves through the streets of Hong Kong, sneaking past and dispatching Killian's thugs as she does so. She retrieves the research documents from a safe house and meets up with Jack at the rendezvous point (the elevator) in a subway. Zeigler takes a Neurodrive from the case Joanna retrieved and uses it to implant information into Jack's subconscious. Zeigler then succumbs to his injuries and dies, all caught by camera in the elevator. Jack and Joanna then proceed to the rooftops, seeking to meet Chandra at the extraction point. Due to Killian's interference, Jack and Joanna are separated and Joanna covers Jack from the rooftop as they make their way to the extraction point. Knowing Jack's subconscious contains Zeigler's research, a dataDyne assault team impedes their progress, assisted by Killian in his Dropship. At the extraction point Killian makes a last ditch effort to end Joanna's life, but she manages to shoot his vehicle out of the sky. Although she escapes successfully with Chandra, Jack is captured by dataDyne.

China
Having used the tracker in Jack's nullsuit to locate him within Zhang Lis mansion in China, Joanna sets out to rescue her father from the wealthy founder of dataDyne. Using her stealth abilities, she infiltrates the mansion. Joanna stumbles in on a DeathMatch session in progress, with Zhang Li's daughter Mai Hem defeating her opponent. The modified DeathMatch rig kills the opponent. Zhang Li notices Joanna, and mistakes her for a professional player. Mai Hem challenges her, and Joanna readily accepts, entering into a virtual reality duel with Mai Hem. Mai Hem has hacked the software and it isn't long before she brings in stone soldiers to support her, as well as making duplicates of herself. Before entering the mansion, Joanna had reprogrammed the server satellite, which allowed Chandra to patch in and give Joanna support in the form of a better weapon. Joanna then defeats Mai Hem.

Zhang Li stops the game before his daughter can be killed. As medical support is called for her, Joanna moves deeper into the facility. Having fought her way to the prison wing, she finds Jack in a cell. He's been tortured, and begins speaking gibberish to her, an after effect of the neurodrive. Together, Jack and Joanna fight their way out of the complex. They steal a Hovercraft and go down the river, arriving at the airbase. Before they can escape Mai Hem appears with a response team. Jack and Joanna are pinned down when Jack steals Joanna's weapon and charges the security team. Joanna, taking advantage of his sacrifice, makes a run to a dropship. Jack takes down a few of the soldiers before being wounded by Mai Hem. Unarmed, he is killed by Mai Hem. Joanna flies near Mai Hem and sets her on fire with the engine in revenge. Joanna then escapes.

Pacific Ocean
Joanna and Chandra decide to pursue Zeigler's lead and seek out Dr. Eustace Caroll, who serves aboard the Trinity research platform that Joanna had infiltrated in the prologue. Shortly after arriving Joanna loses contact with Chandra. She is ambushed by two bounty hunters hoping to cash in on killing her. She kills them and proceeds into the station. Dr. Caroll uses the neurodrive to extract Zeigler's information from Joanna's memory, which she gained when she rescued her father.

The information extracted, Chandra arrives and kills Dr. Caroll at the orders of Zhang Li. Zhang Li has made her a large offer, and she plans to get away with Zeigler's information. As she is about to shoot Joanna, Jonathan Steinberg blows down the door. Chandra gets away, and Jonathan and his team take Joanna to the CPU where they download the Zeigler information. The team fights to the surface and escape in a dropship. Jonathan introduces Joanna to Daniel Carrington via transmission. Carrington informs them that dataDyne is moving a large amount of their forces to a temple in the rain forest in Peru. Joanna agrees to come along.

Peru
Not long into the mission, Joanna's dropship is shot down by the dataDyne ground forces. Joanna and the dropship pilot defend the craft from a wave of dataDyne forces. Joanna sets off into the jungle, steals a jet pack, and flies over to the ancient temple that dataDyne has excavated. She discovers that dataDyne has uncovered an ancient artifact that powers the Graal, an artifact that grants power currently unknown to the human race. She plants a tracking device onto the artifact before sneaking aboard a dataDyne dropship.====Africa==== Exiting the dropship, Joanna learns that Jonathan Steinberg and his team was captured while in Peru. She quickly rescues them before they can be interrogated. The team fights through the desert town and disables dataDyne's air defenses. Their extraction is interrupted by Mai Hem, who has survived the encounter back in China, albeit with large amounts of skin graphs. She fights Joanna, having the advantage of a hovercraft and a mounted turret. Despite the advantage, Joanna avenges her father and kills Mei Hem.

Knowing that Zhang Li cannot be allowed to access the Graal, Carrington sends his forces to the excavation site for an all out offensive. Joanna aids the Institute squads in crossing the bridge, taking on a large contingent of dataDyne forces. Successfully making it across in one piece she watches as Zhang Li gains the Graal's power, which gives him inhuman abilities and a younger body. Zhang Li kills Chandra, sacrificing her to his power. Joanna then faces him in the arena, alone. Joanna manages to come out on top.

The crisis averted, Steinberg and his squad arrive. Seeing that Joanna has stopped the scheme by herself, Steinberg aids her in walking over to Daniel Carrington. Fatigued, she asks Carrington about her performance. "Perfect" is his one word response.
