Arkham Knight Line Of Duty Locations Guide

The Line of Duty side mission in Batman Arkham Knight tasks players with tracking down and rescuing missing crew members from the Gotham Fire Department scattered across the city. Finding every trapped individual requires a keen eye and a solid understanding of the complex architecture across Bleake Island, Founders Island, and Miagani Island. This comprehensive guide details the essential strategies needed to successfully navigate the urban landscape and locate all sixteen firefighters.
Scouring the Streets of Bleake Island
Your search begins on Bleake Island, where several firefighters are held captive by hostile militia groups. One crew member is located at Dixon Docks, while another can be found just northeast of the bridge leading to ACE Chemicals. You will need to engage in close-quarters combat to clear the thugs guarding these public servants safely.
Another group of captives is trapped near the lighthouse and around the Chinatown district. Utilizing Batman's Detective Mode is vital for scanning rooftops and alleyways to pinpoint their exact coordinates. Defeating the armed guards quickly ensures that you can secure the area and send the men back to the GCPD.
Tracking Crew Members on Miagani Island
Miagani Island presents a different set of navigation challenges, with captives hidden on high rooftops and underneath industrial complexes. You can find one firefighter near the Wayne International Plaza and another hidden close to the Grand Avenue rail station. Eavesdropping on thug conversations while gliding across the city can reveal these hidden locations naturally.
A few crew members are surrounded by automated sentry drones or heavily armed brutes, requiring a more tactical approach. Using environmental takedowns and the Batmobile's heavy weaponry can help tilt the odds in your favor during these intense rescue operations. Clearing these areas allows the firefighters to escape the chaotic streets unharmed.
Uncovering the Secrets of Founders Island
Founders Island contains some of the most heavily guarded rescue zones in the entire game, with multiple target areas heavily monitored by the militia. Firefighters are often trapped in deep construction sites or tucked away on the lower ports near the waterfront. You will need to utilize late-game gadgets like the Remote Electrical Charge to manipulate security gates and access these zones.
As you progress through the main story to get access to all of their locations, you will find that a systematic sweep of the northern docks yields excellent results. Some of these encounters involve fighting large waves of enemies equipped with shields and stun batons. Careful positioning and precise combat free-flow styling are necessary to overcome these high-risk scenarios.
Confronting the Mastermind at the Fire House
After successfully tracking down and freeing all fifteen crew members across the three main islands, the final stage of the mission unfolds. Batman will receive coordinates to locate Chief Underhill, who is being held under unique circumstances. This final encounter wraps up the overarching narrative of the missing department crew and provides a surprising twist for players.
Resolving this final objective requires confronting the chief and understanding the underlying motivations behind the mass abductions. Completing this Most Wanted case grants valuable WayneTech upgrade points to further enhance your combat gear. It also ensures that the Gotham City Police Department cells are filled with the criminals responsible for the city-wide chaos.
