Player can find several diaries or similar recordings of past events that reveal all or part of what had transpired, often revealing surprisingly useful info compared to what one would expect from such.
Alternate names: Journals, Logbooks, Audiologs
The first video game about Diaries was released on March 26, 1994.
A curious and common oversight in this is that handwritten journals contain audible thoughts or words from the writer. So there's "wait! what was that sound?" or "AAAAARGH!" written there as they hear odd sounds or get attacked. Conveniently, for audio logs this makes sense (at least the scream of terror).
