A variation on a basic model. A non-replaceable muffler is added.In-game description
A customized Viper 5 sub-machine gun that features an integrated suppressor, making it the perfect lightweight stealth weapon. The Noiseless variant does not suffer from the 20% stat penalty when a silencer is mounted on a weapon, and is actually significantly more accurate (and slightly more durable) than the standard Viper 5.
Shadow of Chernobyl
This weapon is carried by a Loner known as Vampire. He is an assassination target of the Barkeep, since everyone who travels with him mysteriously dies, yet he always returns alive. Vampire can be found in the southern farmstead in the Dark Valley. There is an event that can be triggered by paying his friend 800RU for a "Gauss rifle", resulting in him threatening the player, and becoming hostile if the player enters the farm.
