Scout x locations are just like checkin locations from first watch dogs. The pre requirement is to install the scoutx app to your mobile. Once set open the app and at home screen you have all the locations listed with distance from your current location. You can set a waypoint to go to the location and then open the scoutx app or your camera directly to take a selfie. Do this for 25 out of 57 total locations. Each selfie generates around 8000 followers which are essential for getting research points to upgrade your skills. Also to be noted that not all of the locations are available all the time. Some open up only on day or night.
