Batman Arkham Knight: Militia Checkpoints Guide, Streets of Gotham
Let's see how to complete one of the game's side quests.
How to destroy all checkpoints
"Conquer the streets" is one of the "wanted" side missions of Batman Arkham Knight which, among other things, is also part of the Deathstroke questline. In this mission it is necessary find and destroy the 20 militia checkpoints.
The video you can see above shows where the checkpoints are and how to destroy them without using any special skills. This mission will unlock a little later in the game, unlike the other side missions you will not receive any notification to start it, but it will activate automatically when you get close to one of the checkpoints. There will be no warnings for subsequent checkpoints, however, you shouldn't have any difficulty finding them all with the help of the video.
Destroying all roadblocks and completing the "Conquer the Streets" mission will also unlock the Trophy / Achievement "The Streets of Gotham"
