Tip: Interrogate fleeing enemies to get knowledge
As you can see in the video… After you’ve cleared an area and the enemies are fleeing, tackle one of them like you do a bounty. Then keep hitting them and you will gain knowledge about their factions including locations that get marked on your map!
Note: Sometimes the game doesn’t allow this as it sometimes prompts a cutscene. Or you may have still hostile enemies around that will interrupt your enhanced interrogation.
