Navigating the rain-slicked streets of Gotham City requires a sharp eye, especially when attempting to complete the dramatic Line of Duty side mission. In this particular quest line, Batman must locate and rescue fifteen missing crew members from the Gotham Fire Department who have been taken hostage by various thug groups. Tracking down every single captive requires systematically exploring the rooftops, shipyards, and hidden alcoves across the three main regions of the open world.
Tracking Down the Victims on Bleake Island
Your search begins on Bleake Island, where the narrative naturally points players toward their very first rescue near the northern docks. You can find this initial group of captors holding a firefighter near the shipping cranes at Dixon Docks. Moving further into the island, another group stands guard near the Oracle clock tower, waiting in a secluded lower courtyard.
The remaining captives on this island are scattered across highly industrial landscapes. One crew member is trapped near the Chinatown sector, hidden underneath a stone bridge walkway. The final individual on Bleake Island is located near the Lighthouse, requiring you to dismantle a heavily armed squad guarding the pier.
Scouring the Streets of Miagani Island
Miagani Island introduces more verticality to your rescue operations, forcing players to check elevated structures alongside ground-level alleys. The first notable location is situated near the Grand Avenue station, tucked away inside a multi-level parking garage structure. Another crew member is held hostage on a high roof near the Elliot Memorial Hospital building, which requires quick aerial navigation to reach safely.
Moving toward the southern ports, you will discover another firefighter trapped near the base of the massive Wayne Tower. The captors here utilize advanced weaponry, so checking your surroundings carefully before diving into combat is highly recommended. The final Miagani target rests near the botanical gardens, surrounded by a large group of traditional rioters.
Rescuing the Remaining Hostages on Founders Island
Founders Island contains some of the most challenging encounters in the side mission due to the presence of heavily armored brutes and automated defense systems. A critical rescue point is located near the construction site in the Ryker Heights district, hidden behind breakable walls. Another firefighter is trapped inside an abandoned warehouse facility situated near the waterfront of Port Adams.
To round out your search in this district, you must explore the lower grid networks beneath the main streets. One group of thugs holds a victim near the subway entrance ruins, utilizing tight spaces to ambush unsuspecting players. The final crew member before the grand finale is found on a crane platform overlooking the northern bay area.
Confronting the Fire Chief at the Final Location
Once all fourteen standard crew members are safely returned to police custody, intel will reveal the coordinates of Chief Underhill. The final rescue operation takes place deep within a highly fortified enemy compound on Founders Island. This encounter features the largest gathering of hostile forces, combining shield wielders, weapon experts, and standard thugs into a massive brawl.
Successfully clearing this final area triggers a narrative conclusion that wraps up the story of the Gotham Fire Department. The Dark Knight will automatically secure the Chief and transport him back to the GCPD lockup facility. Completing this journey provides significant upgrade points to maximize your combat capabilities for the endgame content.
