Where to Find all Data-Bios and Implant-Bios collectibles in The Callisto Protocol for PS4 & PS5
Welcome to our The Callisto Protocol Collectibles Guide. There are a total of 43 (20 Data-Bios & 23 Implant-Bios) to find and collect in The Callisto Protocol. Implant-Bios are specifically Data-Bios that you “harvest” from corpses whereas Data-Bios are pick-ups you find while exploring. You will have to find all Implant-Bios as well as the Data-Bios pick-ups to unlock the Grim Reaper trophy. You can track which Data-Bios you have collected and in which chapters by pressing and then to navigate to the Data-Bios tab.

Chapter 2 - Outbreak
Data-Bio #2 - Dr. Caitlyn Mahler: Mahler's Appointment
Quite a fair bit into the chapter you will come across a security robot that you must avoid while trying to make it through the medical wing.
