The Line of Duty is yet another most wanted side mission in Batman Arkham Knight. It starts during the first chapter.
In order to complete it, you have to track down and rescue 16 missing firefighters. They’ve been taken hostage and tortured by thugs all over Gotham. You have to defeat all thugs next to each firefighter in order to set them free. Multi Fear Takedown is something you will love here, as it saves a lot of time.
