The Line of Duty is one of the more time-consuming side missions of Batman: Arkham Knight where you must track down several firefighters. You can start the mission early in the game, right after apprehending Poison Ivy. Speak with Officer Aaron Cash at GCPD to learn about the missing firemen and their chief.
There are a total of 15 missing firefighters including the chief who you need to find and rescue in Batman: Arkham Knight. They are scattered across the Bleake, Miagani, and Founders’ Islands. Each Line of Duty location will be crawling with enemies. You need to take them all out before freeing the fireman. We do recommend surveying the area from above or by using Detective Vision before going in.
Bleake Island
Firefighter 1# – Leary Wood
Leary Wood is held in the Dixon Dock West, inside a security office overlooking the main entrance. There will be a total of 5 bandits, two patrolling the area and 3 inside guarding the firefighter in Batman: Arkham Knight.
Firefighter #2 – Adamson
Head over to the northeast of the bridge to ACE Chemicals to find Adamson across the pier. Adamson is being held by a small number of unarmed thugs who are not difficult to tend to.
There will be a total of 6 unarmed bandits. You can easily eliminate these adversaries to rescue the firefighter. But beware the rioters outside, they may turn out to be reluctant to join in.
Firefighter #3 – Wyatt
Wyatt is held near the cranes between the lighthouse and Falcone Shipping. The hostage is held captive by three armed thugs so use your Predator Skills to tackle enemies from the crane and free the hostage.
Firefighter #4 – Norman
Norman is held at the northeast edge of Falcone Shipping, right next to the water. To tackle the brute, make sure to use the Environmental Takedown with the overhead light. As for the rest of the thugs, they are not hard to take care of.
The strong opponent among these bandits will not give up easily and you will have to use the beatdown on him. You will also find armed bandits near the water, using the jammer against their firearms
Firefighter #5 – Ashley
You will find Ashley tied on a terrace in Chinatown. Grapple to the rooftop overlooking the area and use Fear Multi-Takedown to drop the armed thugs before tending to the thugs with knives using the Blade Dodge.
Firefighter #6 – Cannon
Cannon is held captive in southern Chinatown, across the street from the Clock Tower. Use the Remote Electrical Charge to deal with the enemies equipped with Stun Sticks and use Fear Multi-Takedown to deal with the rest of the thugs in the area.
Unlike other hostage sites, you will find enemies with tasers and shields here. You will have to use the jammer and stomp them to fend off their attacks.
Miagani Island
Firefighter #1 – Green
Seven armed thugs hold Green captive on the east side of Mercy Bridge. It is advisable to use Fear Multi-Takedown from the ledge above, but you must be quick enough to deal with all the enemies or grapple up again to rescue the hostage.
The mercenaries here will also be armed and ready to kill you. So, make sure your fear meter is filled before you get into rescuing Green as it is an open site and is a bit harder than the others.
Firefighter #2 – Hill
Hill is one of the easiest hostages to rescue and is located next to the Gotham Herald Building. The unarmed thugs keeping Hill hostage are not matched for the Caped Crusader.
You will find a total of nine bandits here of which only one is armed. That is the one you have to look out for the most. You can choose to start with the same bandit and the rest will be a lot easier.
Firefighter #3 – Richardson
This hostage is located on the north side of the Grand Avenue Station with 6 Gun Turrets and about 4 thugs.
Head over to the south side of the area to find a switch and use the Remote Hacking Device to open it up. Once this is done, drive the Batmobile inside and deal with all the threats inside before freeing the hostage.
Alternatively, you can hack into one of the turrets. To do that, you have to jump and land on one of the turrets near the enemy and disable it with the RHD. Then you can fight the enemy without the risk of being shot by the turret.
However, beware of staying in the shooting range of that turret to avoid the attention of any other one of them.
Firefighter #4 – Danielle
Danielle is the last firefighter you need to rescue to clear Miagani Island in Batman: Arkham Knight. You will come across about 9 armed thugs keeping him hostage on the southeast edge of Wayne Tower.
Use your Disruptor to render the 3 gunmen on the farthest side useless. Use a Smoke Pellet in the middle of the group and use Fear Multi-Takedown to take down the thugs one by one before rescuing the hostage.
You can also use a large number of obstacles in the room to evade the enemy’s attack if you do not want to use the smoke grenade.
Founders’ Island
Firefighter #1 – Scott
Scott is held captive on the pier on the far north side of Ryker Heights. Once you arrive at the area, deal with the sniper on the lighthouse and a jammer near the trade house on the south side.
For the sniper, you can fly up on him from behind taking him by surprise. The jammer will be blocking the detective mode. You will have to take the enemy operating it down as soon as possible. Not doing that will cause hurdles while fighting other bandits.
After this, use the beams and grates to deal with other enemies and free the hostage.
Firefighter #2 – Bliss
Drop on the enemies from above on the north side of Wayne International Plaza. You will have to deal with 8 unarmed thugs and 2 brutes holding Bliss captive.
When the fight begins, try to keep the enemies away from the ammunition boxes. They might prove to be much more cumbersome if that happens. Also, be sure to use beatdown on the brutes.
Firefighter #3 – Taylor
Use your Predator Skills to take down the 8-armed guards keeping Taylor hostage inside a control room in the heart of Port Adams. It is recommended to deal with the enemies one by one.
Firefighter #4 – Wilson
Head over to the Urban Rail Station in Ryker Heights to deal with about 11 thugs and 3 Brutes keeping Wilson hostage. Use your Fear Multi-Takedown to thin their ranks and drop them one by one to free the hostage.
Firefighter #5 – Lozar
Head over to the lower tier of Ryker Heights and use Winch Anchor Point on the northwest edge of the area to find an opening inside.
Once you come across your foes, use the Disruptor to deal with a couple of armed thugs followed by using Fear Multi-Takedown to finish the rest of the group before freeing the hostage.
You will also come across a few electrified brutes. Use the EMP to un-electrify them followed by a stun with the cape and then use beatdown to end them. Remember that the un-electrification is only temporary and the current will be back in a while.
Firefighter Chief location in Batman: Arkham Knight
The last firefighter that you save will reveal the location of Chief Underhill in Batman: Arkham Knight. Head over to the top floor of the City Vision Building in Ryker Heights. Use a grapple point to analyze the area to find 16 armed thugs roaming the area.
Use all your Predator Skills to deal with these thugs one by one. Chief Underhill will be guarded by another three thugs. Separate them using the Fear Multi-Takedown and eliminate them to complete the Line of Duty mission.
