There are a total of 77 Collectibles in The Order: 1886 - 16 Phonograph Cylinders, 10 Newspapers, 11 Photographs, 16 Documents, 10 Objects, 14 Items. You have to find and inspect all collectible locations to unlock the following 5 trophies:
Inspector First Class [Gold]
Detail Oriented [Silver]
Power of Observation [Silver]
None of the collectibles are missable! You can search for missing items via chapter select at any time during the story or after beating the story. Your progress does also carry over when starting a new game.
Unfortunately, there is no tracker for the collectibles, except for the Phonograph Cylinders (these can be viewed in the "Archive" of the pause menu, but you don't have to listen to them to unlock the trophy). Because there is no tracker it's almost impossible to figure out what you are missing, so be very careful that you don't miss anything. Just to be safe you should always view both pages of every photograph and document and inspect all objects with the left stick.
It doesn't matter on which difficulty you are playing. The collectibles can all be found on easy difficulty or any other difficulty! Almost all of the collectibles are in areas where no enemies are spawning.
The game also contains lots of story-related objects that cannot be missed (doors, ladders, rubble blocking the way, weapons and other gear you are forced to pick up to progress in the game). The unmissable story objects are not inlcuded in this video guide series to minimize spoilers and because they are obtained automatically as part of the story.
There are 17 chapters in total, but many of them do not contain any collectibles at all. The following chapters do not have any collectibles: Prologue, chapter 6, 7, 8, 10, 12, 13, 14, 16, Epilogue.
