"Spend time with your eyes closed or in a limited light situation before heading out for the night."
We all know how to hunt, scavenge, and live our lives during the daytime. But do you know how to do it at night? You are not completely blind when it gets dark — the human body is perfectly capable of functioning in poor-light environments. This book will cover the science behind the cone and rod cells in the eyes, what they do, and how to activate them to use nature's built-in night-vision goggles.
Can be found in any bookstore.
How to obtainEdit
- It can be found while scavenging in the Dead Zone.
This book, when equipped, brightens the playing area, allowing the player to see better at "night". It only appears to be cosmetic.
- An alternative method to brightening in-game maps at night is to turn off static lighting and turn on dynamic lighting in the game's settings. This can be used by players who either do not have the book, or wish to save on a book slot.
