There is a bug/exploit that can be achieved from using specific settings within Overwatch that will give vision of friends and enemies through the walls. This works in all game modes. Not sure if you are aware that this still exists…also not sure how to go into more detail on here without it being exploited.

They’re asking HOW you reproduce this… they can see WHAT is happening, but they want to know how!
