Audio Diary #8 – “Lamb the Problem, Sinclair the Solution”

Across from the last audio diary is a pile of crates with an Eve Hypo, .50 Caliber Rounds and another audio diary. It’s right behind some falling water, and also near a large neon arrow sign that says “Conformity & Co.”

Audio Diary #9 – “Truth is in the Body”

This one’s well hidden. Near “Chaos Corner” and just a bit before the second Andrew Ryan robot is a stairway leading to a series of balconies overlooking the track. Diary is on a workbench between two of those balconies. If you reach the Scientist and Artist animatronic dioramas, you’ve passed the staircase and should go back.

Audio Diary #10 – “Deterioration”

To the right of the animatronic scene with the parents and child is a storage room full of giant hands. Climb the one in the center as if it were a ramp and you’ll find the audio diary on an upper balcony. (Thanks to reader “EngieIndeed”)

Audio Diary #11 – “Working for Sinclair”

Past the animatronic scene with the parents and child watching television is a water-filled room with a Power to the People weapon upgrade station. In a room to the right is an ammunition vending machine and the audio diary.

Audio Diary #12 – “Doctor Lamb”

Near the end of Journey to the Surface, under a security camera, is a Ride Maintenance passage with a Bot Shutdown panel. Continue in here and to the left to find a door covered in wooden boards. Break the boards with melee to reveal a hidden room with the audio diary.

Audio Diary #13 – “Efficacy”

At the end of Journey to the Surface is a miniature lighthouse scene. The door to your left holds a pile of rubble and an audio diary.
