Everyone who likes playing FPS games is or was at some point a military enthusiast so the concept of Night-Vision isn't something new, but for those that do not understand its concept here is a simple explanation.
Humans can only see a small spectrum of light that we call "visible light", so basically NV compensates the lack of visible light by allowing us to see other light frequencies such as Infrared and ultraviolet.
Some interesting facts about Night Vision:
- Most NV images/films are shown as green images because the human eye can differentiate more shades of green than any other color, giving us a clearer image.
- Infrared light goes through some types of clothing making them semi-translucent.
In the game
Night vision in the game tries to mimic Real night vision by changing illumination values according to its distance, meaning the closer you are to your target the brighter it will become to the point where it will become plain white/green.There are three types of NV in the game: Basic(vehicles only), Infra-red (infantry only) and Thermal(vehicles only). Both vehicle NV types have much bigger range than the infantry IR-NV.
Basic and Thermal Night Vision test video:
As you can see from the video, the only difference between the basic Night-Vision and the Thermal is that the basic one tints your screen with a green color and has a slightly bigger viewing range, the Thermal on the other hand makes targets a bit more visible but costs much more to unlock, making the basic NV the most used optics enhancement.
Problems with the Night-vision
Another problem with the infantry NV is that since the game tweaks the illumination over the textures to create the Night Vision, it makes it unusable in the Esamir continent because it's a glacier type map thus everything is already white, this makes near impossible to distinguish white silhouette of players from the white background as shown in the image bellow.
Thanks for reading, good luck and have fun!
