Night vision



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

Overview

 * 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.

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.

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

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.
