If you pass In the Callisto protocol you will find personal data and audio recordings of various characters – from the warden of the Black Tin prison to ordinary guards. Collecting such items helps not only to understand the current events, but also to achieve two hidden achievements. In this guide, we’ll tell you how to find them all.

Before we start describing the location of all collectibles, we want to clarify one point. To gain achievements, you must collect all audio recordings and personal files within one playthrough. If you have completed the chapter and have not found at least one personal file or audio recording, you will no longer receive the achievement.
This is because players cannot make multiple saves in separate slots. Moreover, you are also not entitled to download a single chapter even after completing the game. All progress is only relevant at the time of the current chapter.

Please note that the number of personal files and audio recordings is indicated in a separate menu section at the beginning of each chapter.
