Lost Alpha Wiki

The Storming SGi 5k is an unique assault rifle that appears in S.T.A.L.K.E.R.: Lost Alpha and should have appeared in S.T.A.L.K.E.R.: Shadow of Chernobyl, but was cut.

The weapon was made for warfare in the city. To lessen the weight, some parts were removed or replaced. As a result, there is no way to attach neither a sight nor a grenade launcher under the barrel. But at least it weighs almost half of what it did before.
- Inventory description


  • Unique variant of the SGI 5k.
  • Main difference up to v1.4002 is the reduced weight and quadrupled durability. Starting with v1.4005 the only difference is the preinstalled upgrade for weight reduction (4A).
  • It is a lightweight, powerful and quite accurate rifle, which lacks the versatility of the regular version due to its inability to use attachments.


Lost Alpha

  • Not upgradable in Lost Alpha.

Developer's Cut


  • It lacks the ability to mount attachments.
  • Because of its low weight, it allows player to carry more ammo. This being multiplied with its stats, makes Storming SGi a good weapon.
  • One piece can be bought from Arnie in Pripyat, after player disables the Brain Scorcher (v1.4005).
  • Weapon is not changed by the v1.4007 PRM Weapons Pack.
