This guide shows the complete walkthrough of the “Unruly Brother” main quest in Dying Light 2, which released on 4th February 2022.
Search for Barney (Night)
As the quest starts, your first objective will be to search for Barney. Go to the store at the north portion of Quarry End as shown in the picture below and inspect the door. If you haven’t activated the Larch Windmill, a person will appear and he will ask you to activate it. This is an optional objective and has no effect on the story. But we suggest activating it so that you will have a nearby respawn point if you die during the quest.
Climb up the Windmill and Restore the Power (Optional)
On the right side of the door that you interacted with, you will see a pipe going up as shown below. Use the pipe to climb up to the roof.
Then turn right and jump over the broken bridge to reach the other side. Climb up the ladder ahead to reach the Larch Windmill. Now, climb to the top of the windmill and activate the power.
Search for Barney (Night)
Now go back to the door you interacted with at the start of the quest, and enter the store. Inside the store, there will be a few infected. So, crouch and proceed cautiously. Walk around the infected and you will reach a corpse as shown in the picture below. Investigate with the corpse.
Then go back out from this room. Use your survivor sense and track the footsteps to go to the right side as shown below. Then take the stairs to the upper level.
Upstairs, you will see an infected banging on a door as shown below. Take care of the infected and then interact with the door.
Talk to Barney through the door. You will get a few dialogue options. Whatever option you choose, Barney won’t open the door.
At this point, you will be attacked by a few more infected. Clear the area of the infected. Interact with the door again. This time, barney will open the door. Talk to Barney. This time also, your choices don’t have any effect. Your objective will be updated now.
Follow Birdie’s Trail
Jump down to the lower floor and interact with the handprint near the door as shown in the picture below.
Then open the door and go outside. Use the survivor sense and follow the footprints. The footprints will lead you to a window as shown in the picture below. Climb up the window to enter the house.
As you enter the house, you will see a corpse sitting next to a bed right in front of the window. The trail of the footsteps will end on this bed. There is a hole in the roof above this bed. Climb up the roof as shown in the picture below to reach the upper level.
On the upper level, you will find a staircase. Climb up the stairs and it will take you to a GRE crate contacting an inhibitor as shown below.
Next to the crate is a half-blocked door. Squeeze through the small opening in the doorway and you will find Birdie inside. After a small cutscene, the objective will be updated.
Return to Sophie
Go back to the shed in Bazzar to find Sophie. She won’t be there. Then go inside Bazaar, where you will find Sophie speaking with Carl. This will complete the quest.
