Line of Duty Locations Arkham Knight Every Location for the Mission

10 September 2026 | 4

Rescuing the missing firefighters of Station 17 forms one of the most compelling Most Wanted side missions in Batman: Arkham Knight. The Line of Duty quest requires players to scan Gotham City to locate trapped crew members surrounded by hostile militia forces. Completing this mission not only secures the safety of the city's brave first responders but also unravels a deeper mystery involving Chief Underhill.

Firefighters Located on Bleake Island

Bleake Island harbors several firefighters in high-risk situations across its central districts. You will discover one firefighter held hostage near the Dixon Docks, guarded by armed thugs requiring a silent stealth approach. Another hostage is trapped near the Chinatown market area, where utilizing Detective Vision helps isolate sniper threats before engaging.

Scanning the airwaves or listening for radio distress calls often provides initial clues to their whereabouts. Clearing out these militia enforcers restores control to the northern sector of Gotham City. Each rescued crew member offers valuable intelligence regarding the whereabouts of their remaining team members.

Firefighters Located on Miagani Island

Moving south to Miagani Island presents tougher combat encounters surrounding the captured firefighters. One crew member is stationed near the Grand Avenue Station, surrounded by shielded enemies that require aerial takedowns to disarm quickly. Another group holds a firefighter near the Wayne Tower parking structures, where environmental hazards can be turned against the captors.

Approaching these encounters with tactical upgrades makes managing large crowds significantly easier during fights. Players should prioritize taking down armed sentries first to keep the hostages safe during combat. Rescuing these men brings Batman closer to unlocking the final stage of the side quest.

Firefighters Located on Founders Island

Founders Island contains some of the most heavily fortified enemy positions in the entire Line of Duty mission. Thugs guarding the firefighter near Ryker Heights utilize heavy armor and brute tactics, requiring precise counterattacks. Near Port Adams, another trapped firefighter is surrounded by militia equipped with optic deflection suits that hide them from standard scans.

Navigating these complex urban construction zones demands active use of the Batmobile and grappling hook maneuvering. Using disrupters on enemy firearms before initiating combat prevents sudden hostage escalation. Rescuing every firefighter across Founders Island clears the path toward finding the missing fire chief.

Locating Fire Chief Underhill and Finishing the Mission

After successfully securing all fifteen individual firefighters across the three main islands, Chief Underhill's hidden location becomes available. He is held captive on the northern coast of Founders Island by a heavily armed squad. Eliminating these final captors allows Batman to free the chief and uncover the truth behind the station arson attacks.

The conclusion of the mission requires escorting Chief Underhill directly to the GCPD lockup facility. Resolving this storyline grants substantial upgrade points and contributes significantly toward reaching the Knightfall Protocol ending. Tracking down every location ensures total completion of Gotham's emergency services storyline.
