The Line of Duty quest in Batman: Arkham Knight is one of the most vital Most Wanted side missions available to players exploring Gotham City. Tasked with rescuing fifteen captured members of Station 17 along with their chief, Batman must navigate hostile streets and heavy militia strongholds. Completing this multi-stage objective is essential for players seeking total game completion and unlocking the complete narrative ending.
Understanding the Scope of the Mission
This side quest officially becomes available after locking up Poison Ivy at the GCPD early in the campaign. Officer Aaron Cash alerts the Dark Knight about missing firefighters scattered across Bleake Island, Miagani Island, and Founders' Island. Rescuing these hostages requires a mix of stealth, open combat, and clever environmental puzzle-solving.
Only the first hostage location receives a direct map marker from the game's navigation system. To locate the rest, players must listen for local radio chatter or spot suspicious hostiles gathering in isolated areas. Progressing through the main story gradually unlocks access to the remaining islands where hostages are held.
Tactical Strategies for Hostage Rescues
Each firefighter encounter presents a unique combat scenario with armed thugs, brutes, or automated turrets guarding the area. Utilizing Detective Mode before diving into combat allows you to identify primary threats like gun-wielders and jammers. Taking out key targets first prevents the enemies from quickly executing hostages during the brawl.
Stealth tactics prove highly effective when dealing with heavily fortified hostage sites across Gotham. Employing gadgetry like the Disruptor to disable firearms or the Remote Hacking Device to blind sentry guns gives you a distinct advantage. Initiating fights with a well-timed Fear Multi-Takedown can instantly clear out the most dangerous opponents before they react.
Rescuing Chief Underhill and Finishing the Quest
After successfully securing all fifteen crew members, Batman receives the final objective to save Fire Chief Underhill. The chief is held captive by a large militia squad at the top of an unfinished building on Founders' Island. This final encounter demands extra caution due to patrolling guards and automated defense turrets protecting the zone.
Clearing out the guards allows Batman to free Underhill and uncover the truth behind the kidnapping plot. Once the chief is escorted back to the GCPD lockup, the entire Most Wanted chain reaches its conclusion. Finishing this task grants crucial upgrade points and brings players closer to securing Gotham once and for all.
