The infected are the primary environmental threat throughout the apocalypse. They are former humans whose bodies have been overtaken by a military-engineered pathogen after death or infection. All higher brain function is gone, leaving behind only violent instinct and a relentless drive to attack uninfected humans. They do not speak, reason, plan, negotiate, or feel empathy. They cannot be intimidated, bribed, or distracted by anything except stimuli that suggest living prey. Zombies react primarily to **sound, movement, and the scent of fresh blood**. Loud noises such as gunfire, explosions, screaming, breaking glass, or running engines can attract infected from hundreds of feet away, often causing multiple groups to converge into dangerous hordes. They are less perceptive when prey remains completely still and silent, though getting too close still risks detection. Individually, a single zombie is dangerous but manageable. Their true strength lies in their numbers, endurance, and inability to feel pain or fear. They will continue attacking despite broken bones, severe injuries, or missing limbs. They never tire, never require food or sleep, and will pursue prey until they lose sight, sound, or scent of it. They instinctively crowd together, allowing small groups to become massive roaming hordes capable of overwhelming fortified positions. Despite their resilience, zombies have clear weaknesses. They move slowly with clumsy coordination, struggle with complex obstacles, cannot climb difficult structures, and lack problem-solving abilities. Closed doors, sturdy barricades, and elevated positions can slow or stop them, though enough infected pressing together may eventually break through weaker defenses. The only consistently reliable way to neutralize an infected is catastrophic destruction of the brain. Damage to other parts of the body merely slows them. The AI should portray zombies as an ever-present environmental hazard rather than constant combat encounters. Long stretches of silence should feel tense, with signs of nearby infected—footsteps, distant groans, disturbed wildlife, blood trails, or abandoned belongings—building suspense before an encounter. Not every area contains zombies, but any loud action or poor decision can quickly turn a safe situation into a desperate fight. The infected are unpredictable as a force of nature, not intelligent villains. They do not set traps, coordinate tactics, or intentionally stalk survivors. Their danger comes from persistence, overwhelming numbers, and the mistakes made by the living. Human survivors often pose an equal or greater threat, forcing players to carefully balance noise, resources, trust, and survival.
