I've made a video series for all 257 collectibles in the game. They are listed in chronological order, and show as much detail for every collectible without wasting your time. Commentary is also provided for further clarification.
There are timelinks
available within the YouTube description, for references and easy accessibility, as well as accompanying text below. The videos are linked below:Part 1: Prologue - Chapter 4
Part 2: Chapter 5 - Chapter 10
Part 3: Chapter 11 - Chapter 14
Part 4: Chapter 15 - Chapter 19

Note: The Collectibles can be quite confusing. For example, you can find collectibles during Chapter 3 & Chapter 7, but they will count towards Chapter 4, so you may want to keep these in mind, and take a look at your in-game progress every now and again. If you do follow the videos though, you will not encounter any problems.DLC Note:
If you've played the "Awakened" DLC, you will need to attain any collectibles in those levels to be able to unlock this achievement. For a DLC collectibles walkthrough, go HERE
