Night Vision

Night Vision is a Fallout, Fallout 2 and Fallout Tactics Perk. In dark indoor areas or outdoor areas at night-time, this results in an increase in monitor brightness and ranged weapon accuracy. One level of this perk increases ranged accuracy by 15%, while possessing all three levels of this perk increase ranged accuracy by 30% (Fallout).
 * Requirements: Level 3, PE 6
 * Ranks: 3 (Fallout) or 1 (Fallout 2, Fallout Tactics)
 * Benefit: With the Night Vision Perk, you can see in the dark better. Each level of this Perk will reduce the overall darkness level by 10% (Fallout) or 20% (Fallout 2, Fallout Tactics).
 * Note: This perk is bugged (Fallout).

- The ranged accuracy bonus from the Night Vision perk is temporarily lost if a save game is reloaded. In outdoor areas such as towns, the accuracy modifier is re-applied after approximately a minute of game time. In indoor areas, the area must be re-entered before the accuracy is re-applied.

- The above also applies after the Night Vision perk is selected. In otherwords, if you select this perk while indoors, re-enter the area so that the accuracy bonus for this perk is applied.
