Batman Arkham Knight offers a dense open world filled with intricate mysteries and dark narrative lines that expand far beyond the primary storyline. Among the most compelling Most Wanted side quests is The Line of Duty, which tasks the Dark Knight with locating and rescuing the missing members of the Gotham City Fire Department Station 17. Successfully tracking down these brave individuals requires a mixture of acute observation, stealth mastery, and tactical combat proficiency across the game's three main islands.
Initiating the Hunt Across Gotham
The mission officially registers early in the campaign when players visit the Gotham City Police Department to secure the Batmobile upgrade. However, the game does not provide explicit navigation markers for the majority of the captured personnel, forcing players to explore the dangerous city blocks manually. Listening to localized police radio chatter and scanning rooftops for unusual thug gatherings are excellent methods to uncover these hidden situations.
As you glide through Bleake Island, Founders Island, and Miagani Island, keeping a sharp eye on thermal patterns using Detective Mode will reveal structural blind spots where hostages are typically held. Armed militia forces and heavy brawlers frequently guard these areas, meaning you must plan each structural approach carefully to ensure the safety of the captive civil servants.
Tactical Execution and Combat Strategies
Rescuing each firefighter triggers an intense encounter against varying groups of criminals who will not hesitate to use lethal force when threatened. To prevent the enemies from executing the hostages during a chaotic brawl, players should prioritize stealthy takedowns to thin out the numbers before entering direct confrontation. Utilizing the Environment Takedown mechanic and the specialized Fear Multi-Takedown ability allows Batman to neutralize multiple threats simultaneously before an alarm can be raised.
Some specific locations feature armed guards equipped with firearms or heavy weaponry that require advanced gadgetry to dismantle safely. Deploying the Disruptor tool to jam enemy firearms or using the Remote Electrical Charge to stun brute units ensures that you maintain complete control over the battlefield rhythm. For a seamless experience during these high-stakes rescues, referencing a thorough walkthrough can significantly optimize your tracking path through the rain-slicked streets.
The Final Confrontation and Chief Underhill
Once all fifteen missing crew members have been successfully liberated from their respective captors, the investigation shifts focus toward locating Chief Underhill himself. This final stage unlocks a specialized narrative milestone that leads the Caped Crusader to a heavily fortified location on Founders Island. Here, the remaining criminal faction guards the chief with an increased number of tactical specialists, requiring maximum utilization of your combat arsenal.
After clearing out the final wave of hostile forces, interacting with the chief uncovers a shocking twist regarding the fire department's involvement with Gotham's underworld factions. With the entire mystery unraveled, players must escort the chief directly back to the secure holding cells at the GCPD headquarters to conclude the quest. Completing this overarching objective rewards players with valuable WayneTech Upgrade Points to further enhance Batman's armor and gadget effectiveness.
