My Chief Concerns is a mission in LEGO City Undercover: The Chase Begins. The Fireman is unlocked in this mission.
Walkthrough[]
There is a fire nearby, but Chase is ill-equipped to deal with it. The man in the window will toss down a key. Pick up the key and use it to unlock the alley door. Smash the boxes in here to create a Color Swapper. Change the color in the Robber's Gun and then shoot the panel. Then shoot the switch under that to open the door.
Go through the door and stay in the Robber costume. Crack the safe dial to open the garage doors. Now make your way to the roof and drop through the hole on the roof. Open the costume closet to get the Fireman costume. Use the abilities of this costume to put out the fires in the garage.
Then scale the building the reach another fire blocking the doorway. The fire chief will then be rescued and you can head over to the next mission.[1]
