Here you can find a full The Callisto Protocol Walkthrough with a list of all Chapters. This walkthrough is based on the highest difficulty “Maximum Security”.
The Callisto Protocol has 8 Main Chapters. The game has a linear structure. There are no Side Quests, No Chapter Select, no New Game Plus, and nothing carries over between playthroughs. A 100% Playthrough on the highest difficulty “Maximum Security” takes about 12-15 hours if it’s your first playthrough, but can be done in 7-10 hours if you’ve beaten the game before and already know where to go.
This 100% Walkthrough also covers all Collectibles and Trophies. By following this walkthrough you will get the Platinum Trophy & 1000 Gamerscore in one playthrough. Everything for 100% Completion is included. There are 43 Data-Bios, all of which are needed for the Grim Reaper trophy. They come in two forms: normal audio logs collected in the environment and implants harvested from corpses. Both types are needed for the Grim Reaper trophy.
All non-story trophies/achievements in The Callisto Protocol are missable due to there not being a Chapter Select. However, you can keep Manual Saves throughout the game to reload later for getting combat-related trophies. If you forget a Collectible you must reload the nearest autosave and replay from there to collect what you missed. If you die you must recollect any unsaved collectibles since the last checkpoint.
The highest difficulty “Maximum Security” is available from the start. You can begin on the highest difficulty and if you find it too challenging you can still lower it later in the gameplay settings. You are also allowed to turn on all accessibility settings such as Auto-Dodge and Auto-Aim, this is fine and doesn’t void any trophies/achievements.
Chapters 1 & 2 are the shortest. Chapters 3 & 4 are the longest. Chapters 5-8 are of medium length.
