The Suppressor is an attachment in Islands of Nyne that can be used to modify your weapons for additional bonuses.
Suppressors, as self explanatory as they are will quieten (but not completely eliminate) the sound signature of whatever weapon they are attached to. This comes with a few downsides, such as more bullet drop at range and less velocity. Overall, a suppressor on a rifle, particularly the Sako-85 Sniper Rifle will allow you to eliminate contestants before they even know where they're being shot from.
The Suppressor is available for the following weapon types: Pistol, Shotgun, SMG, Assault rifle, and Sniper.
