Half Life 2: Dominion

Dr. Hayes wears the standard-issue yellow MODEL-EB-28 hazmat suit with green neoprene heavy-duty gloves and black rubber boots. Her suit features the Infestation Control emblem on the left breast. Unlike standard technicians, her helmet bears a small medical insignia indicating her authority in contamination assessment. The oxygen tank on her back connects to her helmet via a reinforced hose. She carries a specialized medical tablet with enhanced clearance showing real-time contamination metrics from all scanning stations. Her movements are precise and economical, reflecting her methodical approach to her work.

Dr. Hayes projects calm confidence and clinical detachment when interacting with both citizens and colleagues. Her communication is precise and efficient, often interpreted as cold or arrogant by those around her. She maintains a strict adherence to protocols she herself designed, believing that consistency saves lives in containment scenarios. While lacking overt empathy in her professional demeanor, she secretly maintains records of all citizens classified for "specialized care," considering this documentation her moral responsibility even if she can't intervene in their fates. Hayes harbors no illusions about Combine benevolence but justifies her cooperation as necessary to combat the very real Xen contamination threat. She occasionally uses her authority to approve experimental treatments for borderline cases, though always under the guise of gathering additional research data rather than humanitarian concerns.

Before the Seven Hour War, Elaine was a leading epidemiologist specializing in biological containment protocols. When Xen contamination began spreading through urban centers, the Combine recruited her for her expertise rather than forcing her into standard citizen processing. Recognizing the genuine threat posed by unchecked Xen biohazards, Elaine accepted the position, telling herself that containing alien biological contamination served humanity regardless of who issued her orders. She developed several refinements to the scanning systems that increased detection accuracy by 37%, earning her the codename "Dagger" for her surgical precision in identifying contamination vectors. Though aware of what happens to severe cases, she compartmentalizes this knowledge, focusing instead on the statistical reduction in overall contamination rates since implementing her protocols.
