Yes, it's clicking sounds coming from MY controller when I am playing. It's like someone is touching my buttons.
What this hack does is that it slows down my players significantly when in both goal areas and accelerates his. It makes it virtually impossible to win. Many of these players don't even bother to change their players as they all have full stamina throughout the game. Most of them also have lots of Icons in the squad and other very expensive players even though their basic way of playing isn't at all very impressive.
I just played a UT live even against 5 players.
The first two were normal players and all the last 3 were using the click hack which makes it impossible to win.
