The Viper 5 is a Sub-Machine gun that appears in S.T.A.L.K.E.R.: Lost Alpha and S.T.A.L.K.E.R.: Shadow of Chernobyl.

One of the best weapons in the sub-machine gun class. During the last decades of the 20th century, it was adopted by the army and the police special forces units in many countries. When it was gradually replaced with more up-to-date models, it appeared on the black market and then the Zone.

Notes Edit

  • It can be modified to use 9x18mm ammo, which would make it easier to have a large, and cheaper supply of ammunition.

Trivia Edit

  • 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.
