The Callisto Protocol Chapter 2: Outbreak – Bios Collectible Locations

The Callisto Protocol Chapter 2: Outbreak contains 3 Collectible Locations. This walkthrough will guide you to all collectibles (Data-Bios & Implant Bios) in chronological order. Finding all Bios unlocks the Grim Reaper trophy. This guide also includes all other trophies & achievements in chronological order to get the Platinum / 1000 Gamerscore in one playthrough.

All of the Collectibles are missable. There is no Chapter Select and no New Game Plus. If you die you must pick up any unsaved ones since the last checkpoint. You can keep track by pressing D-Pad Up > R1/RB > Data-Bios Menu. The game keeps multiple Autosaves, so if you missed something you can reload the nearest autosave and replay from there. You can also make Manual Saves.
