Friend of the Night

 is a perk in Fallout: New Vegas.

Effects
You are a true friend of the night. Your eyes adapt quickly to low-light conditions indoors and when darkness falls across the post-nuclear wasteland.

This perk causes a noticeable increase in brightness at nighttime and shortly after entering any area with low light conditions. The effect is not a gradual one, and its presence can be recognized by a colored tint on the game world reflecting the dominant color of your surroundings (most often light blue when outdoors).

Keep in mind that once taken, the perk will always cause you to see the world differently at night. Because of this, some players might find it annoying, as it ruins the atmosphere of the Mojave Wasteland.


 * The Nighteye effect given is not as potent as the Cateye chems.


 * The usefullness of the perk is debatable, usually not giving enough lighting in Low Light situations, but washing out colour and being aggravating when out of combat, arguably increasing brightness is a good substitute (if a bit gamey) then using up a perk slot.


 * Cancels out the effects of the Varmint Rifle Night Scope

Trivia

 * The blue-tinted nightvision is very similar to the visual effect caused by "Night-Eye" spells in Bethesda's Oblivion.

Bugs
This perk seems to follow the clock rather than ambient lighting conditions. During daytime hours in a cave you have far less light than inside the same cave at night.

In my version of New Vegas (Xbox 360)the perk doesn't work at all. It doesn't change my vision like the cat-eye chem as it claims to do in the game manual, at night, indoors, or otherwise. I was very disappointed. Waste of a perk until it gets fixed.
