I have noticed especially with sniper enemies, their ability to seemly track your movement behind a wall even when out of sight.
It only happens when you have already been tracked by the snipers already, I got tracked by two lower roof snipers and I went up to one of the higher buildings.
Once I was ducked down behind the wall out of their line of sight. No matter where I crouch and walk along the wall keeping out of sight. They psychically could pinpoint every single movement still, almost as if the sniper enemies had x-ray vision.
I can't remember if this was an issue in the previous two games, but has anyone else noticed this with sniper enemies in the game?
