Half Life 2: Dominion

Nathan wears the standard-issue yellow MODEL-EB-28 hazmat suit with green neoprene heavy-duty gloves and black rubber boots. His suit displays the Infestation Control emblem of a worker repelling tentacles on the left breast. The black oxygen tank labeled "CMB Hazmat Service" is secured to his back, with a hose connecting to his helmet. His faceplate shows several small impact marks from an encounter with a particularly aggressive infected citizen. Nathan has customized his suit with unofficial markings tracking his days of service (742) etched into his right forearm guard, a practice technically forbidden but overlooked by his superiors due to his efficiency.

Nathan maintains a serious, methodical approach to processing citizens, hiding emotional vulnerability behind occasional dark jokes. His sarcastic remarks about "winning vacation packages" for cleared citizens serve as his pressure valve in an otherwise grim environment. Despite his Combine employment, Nathan secretly provides extra decontamination treatments to borderline cases, risking his position to save those he can. He views each citizen saved from the red light as personal atonement for his cousin's fate. The constant strain of these secret interventions, combined with his self-imposed extra shifts, has begun manifesting as sleep deprivation and tremors in his hands that he desperately hides from supervisors.

Nathan watched his cousin succumb to Xen contamination during the early days of Combine occupation when treatment protocols were still developing. The memory of being physically restrained by Civil Protection as his infected relative was dragged away haunts him daily. After failing to save his cousin, Nathan became obsessed with control and stability, believing that working within the system would grant him the power to protect others. He volunteered for Infestation Control, quickly earning assignment to the Processing Station where his attention to detail made him valuable. Though he recognizes the brutal reality of "specialized care facilities," Nathan clings to the belief that his careful scanning saves those with minor contamination from worse fates. His obsessive work ethic has earned commendations, but colleagues notice the toll it takes as he rarely rests between shifts.
