What if Metal Gear Rising; Revengance was part of the Bourne series?

The Bourne: Revengeance is a 2010 action hack and slash game co-developed by PlatinumGames and Kojima Productions and published by Vivendi. Released for the PlayStation 3, Xbox 360, and Microsoft Windows, it is a the sequel of The Bourne Conspiracy.

Plot
While providing security detail in Nigeria for its prime minister, Nakembwe, Bourne (now working for Bionic Security, an American PMC) and his team are attacked by rogue PMC Desperado. While Bourne fends off their forces, their leader Fowler kidnaps and executes Nakembwe. Bourne is badly wounded in a duel with Fowler's comrade, Status 23, but Saeger saves him as Desperado escapes. Prof. Johnson later upgrades Bourne with powerful cyborg armor.

Three weeks later, Bourne infiltrates the breakaway nation of Kurdistan after learning that Desperado is leading a military coup there. He plans to capture Muhammed Al-Bashad, an extremist leading the Kurdish forces, to force Desperado into standing down. Desperado anticipates the move and assigns a prototype AI designated LQ-84i to stop him. Bourne defeats LQ-84i in combat and later has it rebuilt as an ally, naming it GR33N. He faces further opposition from Meada, the commander of Desperado's forces in Kurdistan. After Bourne kills Meada in combat, Al-Bashad commits suicide by blowing up an oil tank he is standing on. Bionic assigns Bourne and GR33N to investigate a research facility in Sichuan, China. There, Bourne meets an orphan named Kim, who was brought to the facility to have his brain—along with the brains of several other orphans—surgically removed and shipped to the United States. He learns that Fowler inspected the facility in the company of Senator Benjamin Walker, creating an alliance between Desperado and World Marshal, another PMC. They plan to condition the children's brains to become killers through VR training and place them inside cybernetic bodies to create new soldiers, similar to Bourne. Bourne rescues Kim and the unharvested orphans and takes them to Prof. Johnson.

Bourne resigns and, with GR33N at his side, launches a one-man assault on World Marshal's headquarters in Atlanta, Georgia. Though no longer employed by them, Bionic unofficially provides discreet support throughout. As he fights his way through the city's privatized police force and Desperado soldiers, Bourne becomes conflicted over those he has killed. He begins regressing towards his former life, before finally embracing it when he encounters Status and another operative named Rice. He kills Rice and infiltrates World Marshal's headquarters before locating and killing Fowler. There, he learns that Walker brought World Marshal and Desperado together to exploit Bourne's desire to avenge Nakembwe's death. Walker used Desperado to distract Bourne while he carries out "Operation Dark Arrow": a plan to assassinate the President of the United States during peace negotiations with Russia to ensure another war on terror.

While Prof. Johnson recovers the children's brains, Bourne seeks help from Solis Space & Aeronautics to reach Russia in time to stop Walker. He encounters Status on the way and the pair engage in a final duel from which Bourne emerges victorious. At Solis, Jayden helps Bourne travel to Savatiya Air Base in Russia, where he is attacked by Metal Gear SPID3R, a spider tank piloted by Walker. He reveals that Operation Dark Arrow was a false flag operation, and his true plan was to frame Desperado for killing the United States military personnel at the base, as this is enough to agitate the American people. Walker, with his connections to the PMCs, would win any subsequent election in a landslide, giving him free rein to realize his vision of a survival of the fittest society, fighting and dying only for what they believe in. Bourne destroys SPID3R but discovers that Walker has augmented himself with nanomachines that give him incredible strength and near-invulnerability, destroying Bourne's high-frequency blade. GR33N intervenes and gives Bourne Status's sword, which allows him to kill Walker.

In the epilogue, Bionic receives approval to create a new cyborg staffing firm, allowing them to shelter the orphans' brains and potentially give them a chance at a better life, while Kim and GR33N go live at Solis with Jayden. Although Desperado is defeated and the brain-taking operation defunct, World Marshal remains in business. Bourne decides against rejoining Bionic, resolving to fight his own war.
