Sorry my bad english, I'm Brazilian!
DAYZ is a game that we use stealth to kill our opponents, and simply by squeezing the active microphone down, if there is an enemy nearby already know that we are there, that is, the microphone will deliver us!
The micro activates for anything, even in the inventory if we press down, this bug has to be fixed as quickly as possible, again saying:
Congratulations BOHEMIA INTERACTIVE for the incompetence, with each patch thousands of new bugs, which was to improve incredibly you can get worse, worse what is already horrible actually because the game is unplayable!
