Notes[]
- One very badly damaged model can be obtained from one of the bandits at the Old Factory during the Find the second contact mission.
- Of very important note is that it uses 9x19mm ammo instead of the 9x18 mm rounds meant for your pistol, meaning that if you want to use this weapon, you have to buy 2 different types of ammunition unless it is re chambered to 9x18mm ammo.
- It can be modified to use 9x18mm ammo, which would make it easier to have a large and cheaper supply of ammunition.
- Weapon does not need to be upgraded in order to attach a silencer.
- The v1.4007 PRM Weapons Pack changes the recoil to 34 (9 Single).
Trivia[]
- In Lost Alpha, the weapon's icon, with the wide magazine, seems more reminiscent of a carbine such as the HK53, rather than a pistol-calibre submachine gun.
- In the gamefiles the Viper 5 is often referred to as Gadyuka, the ukrainian translation of Viper (гадюка).
