HT and some of the BK dweebs will be mad at me after the this, but hey, it is only a game they may as well fix it.
Have you ever been killed while you thought you were the only con in the area? Taken hits, look back, but no one is there? Killed by some one that is miles away?
Here is how it works (I know it works with lalas and tempests for sure). Take a lala or a temp above 35K. It has to be above 35K or the bug/exploit does not work. Once up there, use the zoom on the guns. It seems there is a bug that alows infinite zooming while in that alt. In addition, the guns seem to also use the zoom. All you have to do is scan the sky below, see a dot, zoom in, fire, boom.
How do you think some of the elit BKs land 20 kills in a tempest all the time? Not sure if it works in any other planes so you will have to try for yourself.
