Batman: Arkham Knight Walkthrough - Side Missions (Most Wanted): Gotham is on fire
You get access to this mission relatively early. After you have completed the main mission "Crash Site Investigation" (where you are looking for the crash site of the car in which the Oracle traveled), Batman must ask Alfred about the current progress in finding the criminals. As a result, you will learn about the burning fire station.
Use the lifter and put out the fire
The fire station is in Bristol and the best way to get there is by batmobile because you will need to use its lift when you reach your destination. Aim the lift at the interactive latch and start starting the batmobile's engine. At the same time, make sure that the vehicle's speed sensor is in the orange area. Soon after you have started the fire safety mechanism, you will find out that Firefly is responsible for everything.
You need to follow the escaping Firefly on the batmobile. It's not that difficult, despite the fact that the enemy drops explosive and flaming traps on the road. Keep within an average distance of the firefly and do not forget to use the brakes to enter the 90° turn.
Don't try to light a fire on the Firefly, stay in the batmobile chase mode. You need your opponent to run out of fuel in his jetpack (counter in the upper-right corner of the screen). As soon as this happens, close the distance and wait until a message appears about the possibility of Batman being ejected and performing a special takeoff in the air (press the button/ jump button twice).
If everything went according to plan, Batman will automatically get to the Firefly. The only thing you need to do now is to use Beatdown, so you need to start tapping on the melee button. After you deliver a sequence of punches, the Firefly breaks free and runs away.
Now you need to find another fire station that was set on fire by a Firefly. You can do this yourself by reaching the top of any skyscraper and examining any black smoke that will help you find the building. If you don't want to waste time, look at the map - another fire station is located in a boiler on Blik Island. As before, use the lift and extinguish the fire by controlling the engine speed.
After a while, another Firefly chase begins. The premises of this one are identical to the previous ones. So you need to avoid the flames and wait for the enemy to run out of fuel. Then throw Batman towards the criminal and beat him up.
After the Firefly escapes again, find the last, third fire station. The location shown on the map is located in the Otisburg area on Founders Island. You need to put out the fire using the winch in the Batmobile.
Now you can start the last chase after the Firefly. Capture him when he runs out of fuel. This time, the Firefly won't be able to escape. Instead, he will be arrested and the mission ends. Rainbet
