World Marshal, Inc. was a private military company based in Denver, Colorado. Following the downfall of Liquid Ocelot's Outer Heaven in 2014, World Marshal became the largest PMC on the planet, and the largest supplier of cybernetic body parts.

Desperado Enforcement LLC., also known as DESPERADO Enterprises, was an American PMC primarily composed of cyborg mercenaries based in Delaware that was involved in several incidents in 2018. Although claiming themselves to be a PMC, Desperado, just as its name implies, frequently gave aid to terrorists and international criminals.

Samuel's father was the owner of a Kenjutsu dojo in Brazil, their family having a long line of swordsmen. He taught the Uradachi technique, which thought of violence as the final goal. Sam's father was finally killed by one of his students, apparently under orders from a drug cartel. Sam inherited his father's sword and left Brazil, eventually making one last trip back to slay his father's killer, before he left forever.

Sam became a wandering mercenary, taking whatever work he could, and made a name for himself in the criminal underworld. There was even one story that said he took down a squad of 10 armed mob hit men using only his sword. Sam eventually got himself an exoskeleton suit to enhance his already impressive abilities and had his sword, the Murasama blade, modified into a high-frequency blade.

Eventually, Sam learned of senator Steven Armstrong's ties with the World Marshal PMC and set out to take him down for just letting soldiers die while taking no personal risk to himself. However Armstrong and Monsoon, one of the senator's minions in the Winds of Destruction unit, had arranged for Sam to come to Denver, hoping to recruit him. Sam infiltrated World Marshal's headquarters through the sewer systems, in the process, running into the LQ-84i prototype.

It said it had been ordered to kill him, but Sam replied it should make its own choices. The LQ-84i (Blade Wolf) thought about that for a moment, but responded that it couldn't disobey direct orders or its memory would be wiped, before engaging Sam. He managed to defeat it, saying that Blade Wolf hadn't done badly, but he'd won because he chose to fight. Sam entered World Marshal headquarters, where he continued to fight his way through the cyborgs. He finally reached a hangar like area where Monsoon showed up, who mentioned his taking on an entire drug cartel, but said it would've been pointless. Sam just said he'd only been out for revenge, which he'd gotten and Monsoon said they should see what he had now.

He dropped a red phosphorous grenade down to generate a large cloud of smoke, disappearing as a Metal Gear RAY came out to fight Sam. He managed to take it down, only to be called by Armstrong, who said he'd done well, but he needed to come to the top floor to finish things. Sam managed to fight his way up to the rooftop, where he faced Armstrong himself, who thanked him for coming. He asked the senator what his game was and he replied it was Sam's final interview.

Armstrong absorbed the nanomachines from various vehicles around the building, powering up, and the two engaged each other. Sam managed to apparently defeat Armstrong, who asked him to join his cause, so as to end war as a business. Sam admitted that perhaps he'd misjudged the senator and Armstrong asked him to lend them a hand. Sam asked why didn't he just take his and attacked the senator again, finally cutting his hand off. However, Armstrong used the pointed, metallic stump to impale Sam's right arm, badly damaging it. The senator again asked Sam to join him and he agreed. Afterwards, his right arm was replaced with a cybernetic replacement and Sam began performing missions for his new master, alongside the restored Blade Wolf.

Eventually, Sam and Desperado launched an ambush on the convoy transporting N'mani, an African prime minister. Sam easily cut through the lead vehicles and Maverick soldiers, though the prime minister's limousine got away from him. However, N'mani was captured by Sundowner and Sam met him on a train. Raiden eventually caught up with them and tried to stop Sundowner from harming N'mani, but Sam stopped him.

Sundowner left Sam to Raiden and the cool Brazilian wind managed to take him on easily, noting that his skills were self-taught and not half-bad. Sam managed to slash out Raiden's left eye, then said that he was denying the true purpose of his sword and its desire to kill and bathe in the blood of his enemies. Raiden replied his sword was a tool of justice, but Sam dismissed his claims and ferociously attacked him, eventually severing his left arm. Sam said that was what happened when you brought a tool to a sword fight and prepared to finish him off. But he realized Raiden had delayed long enough for the train to emerge from the tunnel and had to retreat from the Maverick reinforcements. Some time afterwards, Sam appeared to Raiden on several holographic billboards as he approached World Marshal headquarters.

Sam questioned Raiden's pursuit of justice, pointing out that the cyborgs he'd been killing were still people. Raiden said they'd chosen their path, but Sam pointed out they had come from desperate situations, which had forced them to join PMCs. Sam told him to turn off his suppressive nanomachines and listen. Raiden suddenly heard the thoughts of the cyborgs he was fighting, realizing for himself that things were not as black and white as he'd believed. As Raiden approached World Marshal headquarters, in a confused haze, Sam came out to face him, asking if his cause was just or if that was "just" what he told himself. Monsoon appeared and started lecturing Raiden on his illusions of righteousness as Sam looked on. As Raiden took on his "Jack the Ripper" persona, Sam was interested in fighting him, but Monsoon told him to report back to their chief.

As Raiden headed towards Solis, trying to stop Operation Tecumseh, Sam showed up to face him one last time, waiting for him with Blade Wolf. Raiden said for a hired killer, Sam wasn't very good at his job, but he said the war was the big payoff. Raiden replied that there'd be big raises all around when World Marshal got all those contracts, but Sam said he was talking about ideals, not money. He went on to say that they'd both heard enough talk about higher causes and that history would decide who's right. As they prepared to fight each other, Raiden said he didn't care who thought he was right and Sam said that was very good, before the two fought.

Finally, Raiden emerged victorious, stabbing Sam through the stomach. He fell dead, but beforehand, he had told Blade Wolf that Raiden had made him start to doubt his choice to aid Armstrong's plan. Depending on the outcome of the duel, he would either continue with the plan or he would leave his sword to Blade Wolf, who could do with it as he wanted. The blade would eventually be given to Raiden during his final duel with Armstrong.
