AUDIO LOGS

CLICK THE TEXT BOXES ON THE MAP TO SEE IMAGES AND MORE INFO

These are numbered in the order you can unlock them as you progress through the game. Meaning after you finish playing as Buck in the mission Tayari Plaza Audio Logs 1 through 7 can be obtained.
If you start looking for them AFTER finishing Oni Alpha Site, where you play as Dutch, you can get all 29 at once but will have to backtrack through the entire city. Getting them in the order I list, as you FINISH the various missions, will save you a lot of time.
Tayari Plaza - 1-7
Uplift Reserve - 8-15
Kizing Blvd. - 16-21
Oni Alpha Site - 22-29 - You want to get all of the Audio Logs completed before moving on to the next mission.
Data Hive VIDEO - 30 (Only after you get the other 29)
