May 07, 2018 The Suppressor is a weapon attachment in Battlefield Hardline. Functioning similarly to its Battlefield 4 counterpart, the Suppressor decreases a weapon's firing sound and hides the player on the minimap when firing, but also reduces the weapon's muzzle. If you start Battlefield 4 on windows 10 and havnt disabled “handsfree telephony as below” all your sound will cut out. 17-sep-201..
