The secret caches are one of many collectibles in Gotham Knights. They contain hidden audio recordings of Bruce Wayne that you can collect to add to your Bruce’s Audio Log collection under the Database menu of the game. They also contain gear for you to loot.
Batman himself left behind secret caches in Gotham City for his Bat family to access in case of emergencies. Each secret cache contains gear that is of your current level. Hence, it is highly advised that you save these secret caches for the late game. That way, when you do loot them, you will receive legendary gear according to your high level.
Bruce Wayne’s hidden audio recordings are an optional side activity in Gotham Knights. The only reward for finding all secret caches is the Gotham City Confidential trophy/achievement and experience points.
There are a total of 12 hidden audio recordings to find in the game. They will become available after you have completed Case 01: Batman’s Last Case. They are marked with a white box-like icon on the map.
If you have cleared all of them on the map, return to the Belfry to reset them. The next time you go on patrol, you will spawn more secret caches.
The following guide will tell you the locations of all of the secret caches in Gotham Knights.
How to start/complete secret cache activities
There is more to the side activity than just looting a cache. When you arrive at the location of a secret cache, you need to step on the floor plate (ID scanner) to begin a time trial. You will then need to reach all of the light beams within the allotted time.
If you reach the last light emitter before the clock expires, you will get a hidden audio recording of Bruce Wayne as well as other loot.
