I'm been in this game for a while, and seem to me than there is a lot of ppls than know exactly where u are also if u have secret agent stealthed and just reborn; it's not a enemy tag works or allert module coz they all the time make the correct choice on varius possibility of where u can be.
Last one this nigth i follow with cam and marke him he never see me and i never move enemy came vs me i'm back to a coulum so he can't see me, he crounch put armor try to left and see than i move to rigth so he goes rigth but i can see this coz i tagged him see the red arrow near the coloum etc etc after all he kill me b4 than i than is supposed than i'm the only one than know what happen.
I ask to Adam and Crytek a very easy mod, after the killcam send also the screenshot of the killer.
So when u are die at least u can see if on the enemy screen there is additional information like where are all players on map, i remember than cheaters use this way a sort of mesh grabbing than track all enemy on map.

Thanks.
