Act of Aggression

Act of Aggression is set in 2025, following the "Shanghai Crash", a global economic collapse engineered by the "Cartel" (a shady organization with presumed roots to anti-communist US participants during the JFK administration), which seeks to use the ensuing economic recession, terrorist acts and the unstable political climate to their advantage, to the point where even the United States Army is involved.  However, the suspicious nature of the Shanghai Crash has led to the United Nations to organize the "Chimera", a covert multi-national task force with cutting edge technological support and free rein to act as necessary. The campaign begins shortly after another of the Cartel's actions, a staged coup d'etat in Baja California, Mexico, draws the attention of the Chimera.

In 2023, Piet Vermaak, a former South African Special Forces captain presumed deceased, is contacted and hired by the Cartel's Olympus Cell leader, codenamed 'Poseidon', to orchestrate the ascension of Raul Escobedo, a businessman with ulterior motives, as a leading political power by deposing the governor of Baja California and forming a separatist state, the "Republica Democratica de Nueva California" (New California's Democratic Republic), plunging Mexico into a civil war that warrants a US Army intervention led by General James Wittel, called by the media the "Hero of Isfahan".  However, two years later, the involvement and exposure of Zhang Yao, a former Chinese hacker with an Interpol arrest warrant (and Vermaak's aide in his operations), draws the attention of Chimera, whose task force under the command of Colonel Greg C. Schaefer attempts to unsuccessfully intercept her by covertly invading the RDNC at the same the US Army launches their offensive.  As Yao is unable to completely destroy her laptop drive before she's forced to evacuate by Veermak, Chimera is able to acquire the remaining data, mostly referencing Escobedo, prompting Schaefer to launch a missile strike at Escobedo's escape train and covertly capture him for interrogation, earning the Olympus Cell's interest in Chimera.

Following Escobedo's capture and transfer to The Hague, the Cartel attacks the International Criminal Court, killing Escobedo in the process, using the Serbian mercenary unit White Wolves under self-promoted Colonel Dragan Vesnic as their military force, backed by cutting-edge technology.  Schaefer is deployed to try and capture Vesnic and any intact military technology as clues, but the Cartel acts beforehand, deploying Veermak to eliminate Vesnic and as many evidence as possible before Chimera arrives.  The evidence points to a possible collusion between Weyland Defense Corps (A main military supplier for the US Army) and the Yueng Corporation (The company which Yao once worked for before joining the Cartel), using the WDC as a front.  Schaefer leads an illegal covert force into the Yeung holdings in China to acquire the data related to Yao and Escobedo.  The operation reveals that most of Yeung Corporation's military assets (including guidance systems for ballistic missiles) were smuggled worldwide via Escobedo's network to Damocles, an influential private military contractor for the United States and Veermak's previous employer, intended on using its control of military assets to coerce the US government into obeying them.

The information is transferred to the US government, which deploys General Wittel to neutralize Damocles (With Schaefer's assistance as an 'observer'), prompting the Cartel to counterattack utilizing experimental orbital weaponry, but Chimera is able to evacuate surviving assets in time.  Simultaneously, the Cartel strikes a blow against Chimera as Veermak is deployed to eliminate captured prisoners and erase retrieved data from a secondary base in South-East Asia.  Knowing that the orbital weapon requires resupplying, Schaefer leads an assault on the Baikonur Cosmodrome with the assistance of the Russian military, securing the Cartel's database, preventing the supplying of the orbital weapon which was intended on striking down the State of the Union address in Washington, D.C. and exposing multiple high-profile US personnel as members of the Cartel, including General Wittel, whom is a high-ranking member of the Olympus Cell, codenamed Hermes.

Exposed, Wittel is forced to escape to Mexico, covered by Veermak, after failing to organize a force of defecting US troops to stand against the government.  Schaefer leads a final assault against Wittel's forces and eliminates him, with Wittel being vilified as the supposed head of the Cartel, as the Olympus Cell disbands, fully exposed.  However, Veermak and Yao manage to escape by deserting the Olympus Cell and joining the Heliopolis Cell, whose leader Osiris grants entry to Veermak and Yao after they assist Heliopolis in being rid of Wittel's incriminating data during Chimera's attack. The Cartel convenes through the secure channels concerning how and if should they deal with Chimera, the decision being made ambiguous.
