The research interface

A research book or skill book is an item in Survival mode that can be researched to increase a survival skill.

Overview[edit | edit source]

Research books are scattered throughout the regions much like normal books, but are rarer and have a non-generic cover. Books can be researched for 4 to 25 hours depending on the book and will give a boost to the player's experience.

Books cannot be researched in the dark, or if the player is too tired, hungry, or thirsty, or have any affliction. Skill books do not exist in challenges.

Research books retain the functions of normal books and can be used for fuel, harvested, and have the same weight. Usually, multiple copies of each book are spawned and can be researched for additional benefit.

In story mode, several items can be found which resemble research books. Unlike research books, these items are instantly consumed when picked up. Instead of increasing survival skills, they unlock tasks for the side missions The Basics of Survival and Survival School. They will appear at the same locations in every playthrough.

Trivia[edit | edit source]

  • Research books were originally many different sizes from each other, and featuring much more diverse covers. In the current build, they share a much more uniform appearance.
