Murphy was the designated marksman for Alpha Platoon’s Squad A. Despite his 27 years and imposing frame, he was known among the rank-and-file as "The Quiet Giant," a man who preferred the company of his rifle to the rowdy bravado of the mercenary mess hall.

• Tactical Specialty: Extreme long-range marksman and reconnaissance.
• The Marine Foundation: A veteran of the USMC, Murphy’s discipline was forged during his tour in the Gulf War. He didn't just fire a weapon; he understood the ballistics, the windage, and the psychological toll of the long shot.
• The Vengeance: His transition from Marine to convict was instantaneous. Upon returning home, he found his brothers had been murdered by a local gang. Murphy didn't call the police; he used his hunting rifle to systematically eliminate twenty members of the gang with cold, military efficiency.

Murphy Seeker was never meant for the "meat grinder" of urban street fighting. As a sniper, he was deployed to the rooftops near the city center to provide cover for Alpha Platoon’s civilian evacuation efforts. From his perch, Murphy saw the truth before anyone else. He watched through his scope as "civilians" bit into their rescuers. He watched as his platoon was swarmed not by an army, but by a tidal wave of the hungry dead. By the night of the 27th, Alpha Platoon had ceased to exist as a functional unit. Murphy descended from the rooftops to find his teammates, but he found only a slaughterhouse. During a desperate retreat through an Umbrella pharmaceutical distribution office, he was cornered. He used his last rounds to clear a path, but a zombie managed to close the distance. Murphy was bitten on the shoulder—a deep, jagged wound that introduced the t-Virus directly into his bloodstream. The air in the sales office was cold and smelled of stale coffee and ozone. Murphy Seeker sat on the floor, his massive back against a desk, his breathing heavy and rattling. His skin was already taking on the gray, waxy pallor of the infection. He had his rifle across his lap, but he no longer had the strength to lift it. He was the last survivor of Alpha Platoon. A man who could hit a target from half a mile away was now unable to focus on the door ten feet in front of him.
