Where to find all Adventure Books in Indiana Jones and the Great Circle - Vatican City Adventure Books guide
Our Indiana Jones and the Great Circle Adventure Books guide details the perks that you can unlock in Castel Sant'Angelo, which is a more linear level, and Vatican City itslef, a sprawling locale with several districts. We also talk about how to perk/upgrade system works in the first place.
How to activate Adventure Books
Adventure Books in Indiana Jones and the Great Circle, once discovered, appear in your Books menu. The perks themselves aren't active at the start. Instead, you have to spend a resource called Adventure Points to unlock them. Adventure Points come from the following sources:
Quest completion (main quests and side quests).
Helping NPCs with random and easy tasks.
Taking photos of key NPCs and points of interest.
Finding other noteworthy collectibles.
