When Bioshock 2 was released in 2010, I created an Audio Diary checklist without exact locations to aid players in their adventure through Rapture. This is helpful if you want to collect all the audio diaries without spoiling how to get them or their precise location in-game. The list includes the greater-area location name and the name of the diary.
Please note that the first (and possibly only) print of the official guide missed one audio diary, Means of Control. This checklist corrects that error.
