Arkham Knight Line of Duty Locations and Firefighter Guide

Conquering the fractured streets of Gotham City in Batman Arkham Knight requires players to look well beyond the main narrative to achieve true completion. The Line of Duty side mission stands out as a highly compelling Most Wanted quest that tasks the Dark Knight with locating and rescuing fifteen missing members of the Gotham fire department. Successfully resolving this massive investigation requires strategic airborne scouting and a deep understanding of how these hostages are distributed across the game's main islands.

Locating the Hostages on Bleake Island

Your search officially begins early in the narrative when the GCPD directs you to the initial emergency situation near Dixon Docks. Bleake Island contains a total of six scattered crew members who are being held captive by aggressive groups of armed thugs. Navigating these early encounters requires players to combine tactical predator takedowns with swift open combat maneuvers to avoid civilian casualties.

Key areas to explore include the industrial yards near Falcone Shipping and the isolated rooftops around Chinatown. Gliding near police helicopters can sometimes provide dynamic audio clues regarding nearby criminal activity on the streets below. Players should prioritize clearing these early locations before the military occupation upgrades the city defenses.

Searching Throughout Miagani Island

Once the central bridges are successfully lowered during the main story, players can expand their rescue operation into the neon-lit sectors of Miagani Island. This region contains four additional firefighters trapped in complex architectural layouts that demand careful environmental observation. Many of these encounters place the captors in tight alleyways or heavily guarded plazas beneath towering skyscrapers.

Look closely around the Grand Avenue station and the lower ports near the Wayne Tower complex to spot the distinctive orange thermal signatures in detective mode. Some groups utilize advanced shielding and heavy weaponry, meaning you must plan your approach utilizing smoke pellets and structural grates. Securing these men significantly reduces the enemy presence in the southern district.

Uncovering the Victims on Founders Island

The final operational zone presents the steepest difficulty curve due to the heavy drone patrols and automated defense networks protecting the streets. Founders Island conceals five hidden firefighters who are frequently surrounded by specialized brute enemies and armed configurations. Reaching these targets often requires players to disable local security terminals or utilize the Batmobile to break through reinforced barricades.

Exploration should focus heavily on the subterranean construction sites and the dilapidated docks near Port Adams. Because these hostiles possess high tactical awareness, striking from the shadows is the safest method to guarantee hostage survival. Once all fifteen standard crew members are accounted for, the final phase of the investigation activates automatically.

Confronting the Final Chief Mystery

Rescuing the entire standard crew allows Batman to track down the exact location of Chief Underhill to resolve the overarching plot line. This final objective leads the Caped Crusader to a heavily fortified compound where the remaining truth behind the disappearances is unveiled. Completing this dramatic encounter officially concludes the side quest and secures a massive upgrade point reward for your utility grid.
