The Burnley District - entrances to the police station and the sewers | Enigma Datapacks Batman: AO Guide
Last update: 11 May 2016
With the Burnley district, three extortion files are connected (18, 19 and 20) and, as much as fourteen different Datapacks located in the police station and in sewers underneath. Therefore, it is worth reminding how you can reach the selected areas in the station, or the sewers and the knowledge of that may come in handy especially if you are not going to collect all of the items during your first stay here.
The GCPD main entrance is locked so, you need to take the door shown in the screenshot, located on the rooftop. This entrance is adjacent to the helipad and you take it for the first time during the Gain access to the GCPD via the rooftop main mission. You, of course, can take your time and not hurry so much towards the entrance because it is being patrolled by the corrupt policemen, armed with firearms that you need to eliminate, or walk around.
The best way to reach the Burnley Sewers is through the manhole shown in the screenshot, which you use for the first time during the Scan the corpse in the GCPD morgue maim mission. It is located in the Western part of the Burnley district, to the North of the police station. I recommend that you take this manhole if you are going to explore the Eastern part of the sewers and the GCPD - Morgue.
You can also access the sewers through another manhole, shown in the screenshot, which is located in the Northern part of the Burnley district. You took this passage for the first time during the Access the sewers beneath GCPD main mission. It lets you explore the Western part of the sewers [Burnley Sewers - West], the Sewers - Water Treatment as well as the GCPD Telecom Room.
