Arkham Knight Line Of Duty Locations And Mission Guide

Batman Arkham Knight presents players with a sprawling open world filled with dangerous threats and engaging side quests that flesh out the narrative of a crumbling Gotham City. Among the most impactful Most Wanted missions is The Line of Duty, which tasks the Dark Knight with tracking down and rescuing the missing members of the Gotham City Fire Department. Completing this multi-layered rescue operation requires keen environmental awareness, precise combat skills, and strategic exploration across three distinct islands.
Initiating the Hunt on Bleake Island
The mission officially begins early in the main story when Batman is directed to investigate a hostage situation near the Gotham docks. Players will discover that local thug groups have taken the first few firefighters captive, surrounding them with armed guards and specialized brawlers. Navigating these early encounters effectively requires utilizing your grappling hook to secure high vantage points and planning silent takedowns to thin the enemy ranks.
Bleake Island holds several trapped crew members hidden away in industrial zones and dark alleyways that are easily missed during standard traversal. Players should look out for distinct auditory cues, such as the panicked voices of the hostages or the aggressive taunts of their captors, to narrow down the search areas. Rescuing these initial victims updates your mission tracker and sets a solid foundation for the broader city-wide search.
Expanding the Search to Founders and Miagani Islands
As the narrative progresses and access to the rest of Gotham opens up, the difficulty of the rescue operations escalates significantly. On Miagani Island and Founders Island, the enemy compositions guarding the firefighters become much tougher, introducing shield-wielding brutes and optical-camouflage ninjas. Approaching these heavily fortified positions requires a balanced mix of quick-fire gadgets and fluid combat tracking to protect the hostages from collateral damage.
Many of these mid-game locations are tucked away on elevated rooftops or hidden beneath massive suspension bridges, demanding creative pathfinding. For instance, can be found by systematically scanning the lower construction tiers and harbor structures using Detective Mode. Balancing your exploration habits between the high skylines and the lower street levels ensures you do not overlook these highly isolated groups.
Rescuing the Fire Chief and Closing the Case
After successfully tracking down and freeing the fifteen individual firefighters scattered across the map, the final phase of the mission activates. Batman learns the location of Fire Chief Underhill, whose captivity reveals a deeper, more tragic narrative twist regarding the origins of the city's sudden arson crisis. The final stronghold features a large group of armed militia soldiers, making a direct frontal assault incredibly risky for unprepared players.
To secure a clean rescue, players must master their environmental fear takedowns and disrupt enemy firearms before initiating the final brawl. Once the area is completely cleared, escorting the chief back to the Gotham City Police Department precinct closes out the case file. This successful resolution rewards players with valuable WayneTech upgrade points and provides a satisfying narrative conclusion to one of Gotham's most dedicated public services.
