The Callisto Protocol isn’t a long game, taking about 10 hours or so to finish, with only 43 different collectibles throughout its eight chapters. There are two types of collectibles – Implant Bio Harvests and Data-Bios Audio Logs.
While you’re not required to collect these, they are essential for full Trophy/Achievement completion. However, there are several challenges, starting with no Chapter Select. If you miss any collectibles, you must reload a checkpoint and get them. New Game Plus isn’t available, so you can’t start a new playthrough with existing collectible progress.
Even worse is how checkpoints work. If you die, all progress is reset to the last checkpoint, and any collectibles must be found again. Here are all the collectibles available in each chapter:
- Chapter 1: Cargo – One Data-Bios Audio Log
- Chapter 2: Outbreak – Three Data-Bios Audio Logs
- Chapter 3: Aftermath – Two Data-Bios Audio Logs and six Implant Bio Harvests
- Chapter 4: Habitat – Four Data-Bios Audio Logs and three Implant Bio Harvests
- Chapter 5: Lost – Four Data-Bios Audio Logs and four Implant Bio Harvests
- Chapter 6: Below – Three Data-Bios Audio Logs and two Implant Bio Harvests
- Chapter 7: Colony – Two Data-Bios Audio Logs and five Implant Bio Harvests
- Chapter 8: Tower – Four Data-Bios Audio Logs
