On this page of our guide to Star Wars Jedi: The Fallen Order you will find a list of all secrets / collectibles available in the game. Our collectibles and secrets guide has been divided according to the planets on which they can be found. In addition, we have prepared separate pages depending on the type of collectible you are dealing with.
In Star Wars Jedi: Fallen Order, the two most important collectible categories are Chests and Secrets. The game constantly displays information about your progress of collecting them (in real time). You can read about them on the galaxy map (in the example shown in the picture there are 27 crates and 5 secrets on the planet Kashyyyk) and from the level of holomap (separately for each region).
You can't get to all collectibles right away. Some of them are located in places that can be reached only after gaining new skills or after you have advanced enough in the main story. We inform about this type of difficulties in our description concerning collectibles.
