In Batman: Arkham Knight, the Line of Duty side-mission stands out as one of the most compelling Most Wanted objectives available in Gotham City. This optional campaign charges players with the critical task of rescuing fifteen missing firefighters from the Station 17 crew scattered across various districts. Successfully tracking down these hostages rewards the Caped Crusader with precious upgrades and ultimately leads to unmasking a shocking betrayal within the department.
Locating the Captured Firefighters on Bleake Island
Your search begins on Bleake Island, where several members of the crew are being held hostage by heavily armed thugs. One firefighter can be found near the docks, tucked away behind a warehouse where a small group of rioters guards him closely. You must utilize your detective vision frequently to spot the heat signatures of these scattered groups through solid walls.
Another crew member is trapped near the Falcone Shipping Yards, surrounded by a sophisticated automated turret defense grid. Players should clear out the surrounding enemies before trying to disable the active firearm security machinery safely. Finding all targets in this initial zone helps build your early momentum and unlocks essential upgrade tokens.
Tracking Hostages Across Miagani Island
Moving over to Miagani Island requires a mix of diligent exploration and careful monitoring of localized radio chatter from the militia. One group of captors has set up a secure perimeter on the roof of the Grand Avenue station building. You can use the Batmobile or a high-altitude glide to ambush this particular squad from above without alerting nearby patrols.
A separate victim is trapped inside an underground parking structure near Wayne Tower, which requires careful tactical positioning to infiltrate. The militia forces here often utilize martial arts experts and heavy brutes to protect their valuable tactical prisoners. Defeating these specialized units demands precise combat timing and the smart implementation of your quick-fire gadgets.
Rescuing the Remaining Crew on Founders Island
Founders Island contains some of the most heavily fortified enemy positions encountered throughout the entire investigation campaign. A firefighter is hidden deep within the slums of Ryker Heights, surrounded by a large contingent of well-equipped mercenaries. Players must systematically eliminate the sniper units watching over the area before initiating a direct physical assault.
The final standard rescue operation takes place near the Port Adams docks, where a massive brawl awaits the Dark Knight. This encounter features a diverse mix of weapon-wielding thugs and environmental hazards that can disrupt your standard combat flow. Maintaining a high combo meter allows you to perform instant takedowns and wrap up the street combat quickly.
Confronting Chief Underhill and the Final Trial
Once you secure all fifteen individuals across the three main islands, the dark truth behind their disappearance finally comes to light. Chief Underhill has been coordinating with the super-villains to secure financial safety for his men at the expense of Gotham's stability. Batman must track the compromised official to his final coordinates to resolve the investigation permanently.
Confronting the chief does not involve a massive boss fight, but it delivers a powerful narrative resolution to the side quest. After a tense conversation, you will escort the official directly to the Gotham City Police Department lockup. This final action completes the mission requirements and ensures the safety of the entire city rescue force.
