So ever since the update I have great trouble consistently getting shots. I have a few questions if someone can help please. I get headshotted very fast over and over by people and I cannot do it. What method do you use? Using PIB do you aim then and swipe up at the same time ? Do you go into deadeye same time you aim gun and then swipe up ? Do you aim and swipe at the same time ? I'm need exact control details. I can get headshots on the second shot with PIB after missing the first. Any help would be greatly appreciated.
