Alterity Experience (UP)

Notes: This game is sometimes unclear about what triggers the next stage of events that allow you to progress in the game. Some items require progression to be able to read. Achievement may not unlock even with this checklist. If you die you might want to speedrun all of the documents again to be sure. I found logging out of the game and back in might trigger the achievement to register upon hitting continue. Game autosaves after progression to a checkpoint.

Important:
Many documents are listed with pages to scroll; make sure you scroll through all of them.
It appears you must find all documents in one playthrough and some locations are randomized.
You must find all the documents before opening the toybox or you could lock yourself out of things in the Bunker.

There are 25 Documents that seem to be required for the achievement and are listed approximately in order of discovery by room.
