Welcome to MissionChief Unofficials "Realism Location Marker"
I have created a Tampermonkey script to show real building locations within the game on the map, I have created 3 versions and they are as follows:
Realism Location Marker V1 Automatically gives you the address details on a popup within the map see below
Realism Location Marker V2 shows a popup that gives you the option to view the coordinates on Google maps see below
Realism Location Marker V3 Shows a popup that gives you the option to view the coordinates on OpenStreetMap that the game uses therefore very accurate
We will be adding more building types but currently these are the types of buildings currently available see below
You can get it from our Missionchief Unofficial GitHub We also have it working on Android mobile phones using FireFox web browser with Tampermonkey extension.
You can reach out to me on our Discord just tag me "Madpugs" all the best
