Halo 3: ODST Guide
Audio Log Locations
There are 30 Audio Logs to find. Each Audio Log will reveal the story of a girl named Sadie. Finding one, three, 15, and all 30 of the Audio Logs will each unlock an Xbox 360 achievement. Furthermore, as you collect more Audio Logs you’ll unlock Supply Caches around the city. Each Supply Cache unlocked will be marked on your map. Travel to a Supply Cache to find an assortment of weapons and possibly a Mongoose or two.
Terminals will be outlined in yellow while VISR is active, so leave it on while searching for the logs. Car alarms, flashing lights, and ringing payphones all tell of a nearby terminal.
Twenty-nine of the Audio Logs are in the Mombasa Streets hub and the last one is in the Data Hive level. To find the Audio Log hidden in Data Hive, one must first find all 29 Audio Logs in Mombasa Streets. This is best done solo after having completed the campaign once solo or co-op. Once the campaign has been completed, you can then select the “Mombasa Streets” level, where all areas of the city are unlocked from the get-go. Find all 29 Audio Logs in Mombasa Streets during solo play, then save and exit and load the Data Hive level to get the last one. This is best done on the Easy or Normal difficulty level since you will encounter plenty of Covenant while scouring the city.
Advising that the Audio Logs be collected during the solo campaign is not to say they can’t be collected during co-op play. They can, but there may be some complications with the collected Audio Logs saving upon exiting a co-op session. If you’re determined to find the Audio Logs in co-op, try to do so in one sitting, which shouldn’t be a problem with a few buddies.
It’s also possible to collect the Audio Logs your first time through the campaign. Some parts of the city will be locked before and after certain missions, however, so you’ll have to plan ahead and collect the Audio Logs in the areas accessible to you before and after each mission.
Match a marker on the map with the corresponding video for a clear demonstration of the location of that Audio Log.

Audio Log 30/30: Collect all 29 Audio Logs in New Mombasa and then start (or replay) the Data Hive level. If you have fulfilled this prerequisite, the friendly NMPD officer you encounter during the level will follow you down to sublevel 9 (the second data-stack you come to). Normally he’ll remain on sublevel 8 and die.
To find the last Audio Log you must keep the officer alive through the Brute-packed corridor. When the last Brute falls, follow the officer to a locked security door. When he heads through, follow him in and look for the terminal along the northwest wall. Activate it to unlock the Audiophile achievement. The NMPD officer will then turn hostile; he’s armed with a Shotgun, so kill him quickly.
