Maybe I am a newb for asking this, but I have noticed when bringing up the lightening strike that sometimes a pulse goes across the screen showing where the enemies are (like one sweep with the UAV) and other times the pulse does not appear. I thought this might have to do with whether there is a UAV up or not, but this does not appear the case. Is there a reason why sometimes the pulse occurs and other times it does not? It seems like for a while it used to always pop up, and now it does not that often. Maybe I missed something.
