Batman Arkham Knight The Line Of Duty Walkthrough

Batman Arkham Knight offers an expansive open world filled with dangerous side missions that test the Dark Knight's detective skills. One of the most compelling narratives is The Line of Duty side quest, which requires players to hunt down and rescue fifteen missing firefighters from Station 17 scattered across Gotham City. Completing this arduous task is essential for players aiming to achieve full game completion and witness the ultimate Knightfall Protocol ending.
Tracking the Heroes on Bleake Island
The quest naturally commences on Bleake Island, where players receive initial coordinates to search for the first missing crew member near Dixon Dock. Eivor, or rather Batman, must utilize Detective Mode frequently to scan rooftops and alleys for gatherings of hostile militia thugs holding the victims hostage. There are six firefighters in total trapped across this starting island, requiring careful observation and quick combat skills to clear out the heavily armed guards.
As you progress through the main story, more locations become accessible across the harbor lines and shipping docks. It is highly recommended to secure the immediate perimeters before diving into combat, as some locations feature thugs equipped with firearms. Rescuing each individual provides vital clues regarding the whereabouts of the rest of the crew and their missing chief.
Searching the Streets of Miagani Island
Once the narrative grants access to Miagani Island, players can uncover four additional firefighters who desperately need rescue. These encounters escalate in difficulty, often placing the victims on elevated platforms or near prominent landmarks like the Gotham Herald building. You will need to employ sophisticated fear takedowns and quick gadgets to swiftly neutralize large groups of enemies before they can harm the hostages.
One particularly tricky location places a firefighter on a platform attached to the complex rail-track system near Kingston. For this specific challenge, utilizing the Remote Hacking Device becomes incredibly useful to blind nearby sentry guns. Managing the battlefield dynamically ensures that Batman can free the city's bravest protectors without taking unnecessary damage.
Rescuing the Remaining Crew on Founders Island
The final phase of the investigation shifts focus toward Founders Island, which contains the remaining five crew members alongside their leader. The hostile forces here are much more organized, employing snipers, active radar jammers, and heavy tracking elements to fortify their positions. Players must systematically dismantle these defenses, occasionally utilizing the Batmobile to blast through structural walls to reach hidden underground chambers.
Before you can initiate the final rescue attempt, you must ensure that every single lower-ranking firefighter has been successfully returned to safety. After clearing the final port location, the exact coordinates of the captive Fire Chief will finally be revealed to the player. Confronting the ultimate captor triggers a narrative conclusion that brings closure to the tragic story of Station 17, allowing players to secure the coveted Death of Innocents achievement.
