Professor Jones in Indiana Jones and the Great Circle is a scholar more than an action hero. Sure, he will pull off plenty of death-defying stunts while solving puzzles, hunting down collectibles, and fighting Nazis across his globe-trotting adventures, but combat will never do a thing to add to or improve your abilities. Instead, Adventure Books are the keys to unlocking new and better skills. Sadly, Indy never makes a pitstop to a library on his quest, so we have to find these valuable tomes ourselves. Let’s study up on all the Adventure Books in Indiana Jones and the Great Circle and how they work.
How Adventure Books work
Indiana is smart, but apparently not so smart that just finding an Adventure Book is enough to learn all its secrets. Collecting the book is just the first step, but unlocking its ability requires you to go into the Books tab of the menu, highlight it, and spend your Adventure Points to unlock whatever skill it can grant you. Once you have unlocked it, that skill will be permanently active from that point forward.
