Always every Play who plays Capture the Island on the MP have the same Problem.
After you shoot the Bos will find you very fast but if they don´t have find you and you are the one who has find them ,you have the luck to kill them example if they are in 3 Men Squads,but if you hit the 3rd one ,you see how he is bleed but don´t die´s like a Player who has Godmode in everygame and then this Bot gives you a Headshot.
This not Realistic and not Fair.
It´s Impossible to kill that Bot.
