Audio Diary #1 – “Patronage”
Fight the first Houdini Splicer in the large room with the covered statues. East of that room, in the area that leads to the exit staircase, is the audio diary.
Audio Diary #2 – “A Gift From Billy”
Climb up the stairs to exit the first big room with the covered statues and Houdini Splicer encounter. Before leaving through the door here, however, continue back down the stairs on the other side. This way ends with rubble, but also the most unlistenable audio diary in the game.
Audio Diary #3 – “Lamb’s Time is Over”
When you use Billy’s code to unlock the door above, you’ll find a rose (aww), a weapon upgrade station and another audio diary.
Audio Diary #4 – “Lamb’s Idea of Art”
In the room after climbing a frozen stairwell, but before reaching the carousel. Some Splicers will be arguing over a ruined vending machine. The audio diary is at the feet of one of the statues.
Audio Diary #5 – “Lost and Found”
Center of the carousel.
Audio Diary #6 – “Lamb Flouts the System”
In the arched promenade that connects the three artistic areas. The audio diary is near the central statue, tucked under a fallen trash can.
Audio Diary #7 – “Learning Poker”
Head to the Triton Theater, then to the basement lounge. At the back, through a locked door that you must hack open, is this audio diary.
Audio Diary #8 – “Growing Up”
In the Triton Theater, follow signs up to the Projection Booth. Across from the booth room’s door is a pile of rubble with the audio diary.
Audio Diary #9 – “A Spy”
The edge of the theater balcony.
Audio Diary #10 – “A Secular Saint”
Go through the door to the left of the theater screen. The audio diary is at the end of the hallway.
Audio Diary #11 – “The Voice of the Self”
On the piano in the Piano Bar.
Audio Diary #12 – “Falling Into Place”
Inside the frozen Imago Gallery, near the Little Sister vent in the back. You’ll have to thaw some ice to grab the audio diary.
Audio Diary #13 – “Gotta Keep It Together”
Back of the J. Fischer Gallery, next to the Drill Specialist tonic.
Audio Diary #14 – “Dionysus Park’s Weakness”
In the first room of Basement Storage. Climb up the short stairs on either side and you’ll find the audio diary propped against a flooding door.
Audio Diary #15 – “A Plan”
At the very end of the level, in the newly opened security booth with Stanley Poole.
