There is a total of 34 Collectibles in Chapter 10: End of Days. 5 of the Collectibles are Story-related (unmissable) and will unlock naturally. You will be during a lot of backtracking during this Chapter after completing after creating the Master Security Clearance (also included in video).

Below the video you’ll find a full list of all Collectibles. The video covers everything that you need to collect which are missable. If you miss a physical Log, you can return later and pick it up.

Everything on the USG Ishimura (except Collectibles and a Trophy earned in Chapter 9) can be collected up until the point of no return in Chapter 11, except certain Logs triggered by certain actions in different Chapters. At the end of Chapter 11 you’ll be prompted with a dialogue box asking you if you want to leave the ship.
