Detailed walkthrough
Go to the Lynn Pier Parking structure when prompted and kill all the Gunners there. Read the note picked up from the body of the nearby Vertibird pilot, Sparrow, and fly to GNR plaza. Upon arrival, the player character and the Good Fighters will be attacked by two waves of Talon Company mercenaries. After defeating them, go inside the GNR building and eliminate the rest of the Talon Company mercenaries. The corpses of the Good Fighters' senior members can be found throughout the building, as well as unique mercenary outfits and collectable loot. Upstairs, the leader of the Talon company mercs (Hatton) must be killed. Shut down the transmission beacon to complete the quest.
