Silencer (DXMD)

The NS-X20 Silencer is a weapon attachment in Deus Ex: Mankind Divided.

Description
''The NS-X20 is an aluminium-titanium sound suppressor that is easily adaptable to almost any firearm, installed in seconds, it fits snugly over the barrel of a weapon to ensure that, when the gun is fired, most of the sound is muted. Reports are audible only within a very close range. The attachment is compatible with most firearms on the market.''

Gameplay
The silencer is useful for stealth-based tactics by suppressing the sound of gunfire. Enemies standing too close to the player or the shots' impact zone will still get suspicious, however.

Besides actual combat, silenced weapons are also useful for destroying disabled cameras and destructible doors without attracting attention. Generally, after you peg the first badguy, the gig's up, and remaining hostiles will be on high alert, as well as going to strong cover if they can't actually see the shooter (Adam's) location, thus it's recommended that the player has a plan before attempting stealth-based lethal gameplay. If things get very dirty (and they inevitably do), it's typically smarter to remove the silencer and finish the opposition quickly, than risk extra damage.

Reference the actual weapon's page if you want to know how much the silencer actually impacts damage. For things like the elite combat rifle, there's very little reason to ever take it off, same with the elite pistol.
