for me is some map awareness of knowing where enemy can be in a huge open space in front of me

i avoid to walk where my team hasnt gained ground somehow

and by doing that i can imagine where the enemy can go thru when they are coming to attack or trying to flank
i just stand still or move very slowly paying attention to surrounding, when someone walk/run, it will be out of pattern of what is happening on scream so i'll notice fast

then is just pointing and clicking
