In “Indiana Jones and the Great Circle,” collectibles are not missable, meaning you can find and collect all of them throughout the game without missing any. However, the game’s design allows for a more efficient and enjoyable experience by using collectible maps, which are essentially adventure books that unlock new map markers for various types of collectibles.

Here’s a detailed breakdown of how to approach collecting all the available items:

1. Exploration Books:
– These books can be purchased from characters or earned through completing specific fieldwork side quests and mysteries.
– For example, the Vatican Relics book can be obtained by solving the House of God mystery, which involves pulling levers to open compartments and revealing a medallion and a chalice. Placing the chalice in the center square opens a compartment containing the Vatican Relic map.

2. Using Collectible Maps:
– Once you have an exploration book, it will add markers on your map for specific types of collectibles.
– However, these icons only appear when highlighting or currently tracking the related Discovery Quest in your journal. You may need to physically travel to different parts of the region to see if new icons have appeared.

3. Collectible Types:
– The game includes various types of collectibles such as Notes, Adventure Books, Medicine Bottles, Ancient Relics, and Lost Relics.
– Each type of collectible can be highlighted using specific exploration books, making it easier to locate them throughout the game.

4. Efficiency Tips:
– To make collecting more efficient, you can purchase or earn exploration books early in the game. This will help you track down collectibles more effectively as you progress through the story.
– Additionally, completing fieldwork side quests and mysteries can reward you with additional exploration books and other collectibles.

In summary, you can get all the collectibles in “Indiana Jones and the Great Circle” by using the provided exploration books and completing various fieldwork side quests and mysteries. The game’s design ensures that all collectibles are accessible and not missable, allowing you to collect them throughout your playthrough.
