Night vision or NV is a suit accessory that appears in all S.T.A.L.K.E.R. games.


  • The player starts the game with a Flashlight as part of their basic equipment and a standard Leather jacket which has no Night vision capability.
  • Although the player starts out in daylight, this obviously changes as the game progresses. Weather conditions may also deteriorate and impair visibility.
  • Underground locations may be poorly lit.
  • A flashlight can mitigate these shortcomings, but Alkaline batteries are short in supply early in the game and have a lifespan of 3000 seconds (50 game minutes)
  • The use of the flashlight will also compromise the player's stealth against NPCs.
  • For these reasons alone, it becomes desirable to wear a suit that also has some form of Night vision.

Types of NV

First generation

  • As may be seen in the images, 1st Gen NV provides a better world view than no NV but the image is noisy and green which is less than restful on the eyes.
  • It is a lot better than nothing.

Second generation

  • This shows up as a more restful and less noisy violet enhanced world view which is much superior to the 1st Gen NV.

Enhanced second generation

  • This type of Night vision is only available in the Developer's Cut.
  • The view is even less noisy.


  • Night vision operates on the principle of photomultiplier optical enhancement. Without ANY light there is nothing to enhance so their operation in exceptionally dark areas will be boosted by flashlight use.
  • Night vision accessories do not use any battery power nor add any mass to the player's suit weight.


The concept of providing Night vision capability for armour has changed significantly from Lost Alpha (-v1.3003) to Developer's Cut (v1.4000+).

Lost Alpha

  • In Lost Alpha suits come either without any NV capability or with First or Second generation NV by default.
  • Unique suits may not be upgraded, all other suits are upgradeable to at least First generation NV.
  • NV capability is only available through upgrades, there are no NV devices.

Developer's Cut

  • In Developer's Cut suits by default come either without any NV capability or with First, Second or Enhanced second generation NV.
  • Upgrades to the NV capabilities are only available for the Exoskeleton (First generation to Second generation) and the Exoskeleton's prototype (None to First generation).
  • The Developer's Cut introduced Night vision devices.
    • A specific slot on the player's belt can be fitted with such a device.
    • The slot works similar to the slots for detectors or binoculars, so a Night vision device can be used with different suits.
    • It is not possible to use an NV device with suits having built-in NV capabilities.

  • The SSP-99 Ecologist may be downgraded to First generation NV, clearly a bug (Lost Alpha only).
