AI Director Threat Classification
The AI Director orchestrates 7 mutated infected classes tailored to break squad formations, punish stragglers, and escalate tension.
Boomer
Swarm CatalystVomits bile that blinds survivors and summons a frenzied common infected horde. Detonates upon death, splashing nearby targets.
Shove away before shooting to avoid bile explosion radius. Eliminate at extreme long range before it closes distance.
Hunter
Ambush PouncerLeaps across rooftops and alleyways, pinning a survivor to the ground and inflicting rapid, fatal claw strikes.
Listen for growls and shrieks. Melee shove mid-air to deflect pounces; teammates must immediately shove or shoot to break pins.
Spitter
Area DenialLaunches long-range biological acid reservoirs that pool on the ground, dealing rapidly escalating damage to anyone caught inside.
Never camp in tight choke points. Disperse immediately when acid lands; prioritize precision fire while she recovers from spitting.
Charger
Line BreakerCharges at high velocity through squad formations, knocking teammates aside, grabbing one survivor and slamming them into obstacles.
Sidestep the linear charge path or bait him into solid walls. Focus concentrated automatic weapon fire during collision recovery.
Jockey
Displacement ControllerClambers onto a survivor's head and forcibly maneuvers them away from teammates into hazards, fire, or acid pools.
Maintain tight squad spacing. Teammates must shove immediately upon latching to free the victim before separation occurs.
Witch
Passive HazardWeeps in dark corridors. If startled by flashlight beams, gunfire, or close proximity, she frenzies to instantly incapacitate her target.
Turn off flashlights and bypass with wide clearance. If engagement is unavoidable, crown with point-blank shotgun blast or burn with Molotov.
Tank
Juggernaut BossImmense physical health and devastating kinetic force. Punches survivors across the street, throws concrete slabs, and smashes vehicles.
Set on fire immediately with Molotov cocktails to trigger burn duration. Kite across open avenues while entire team unloads continuous fire.
