There is a lot to explore in Halo 3 ODST on Xbox 360 by Microsoft, and every truth you learn, every secret you uncover gets you more engaged and curious about the narrative. Audio Logs, riddled throughout the map, are such an aspect to Master Chief’s story and our Audio Logs locations will brief you on all the locations with clear instructions.
Halo 3 ODST Audio Logs Locations
Apart from getting key details about the game’s world and the plots revolving around our characters, Audio Logs serve as collectibles so if you’re the completionist type, you cannot live without them.
Moreover, you will also unlock Supply Caches around the map for listening to these Audio Logs. Supply Caches provide you with weapon ammo and Mongoose.
It is advised to first complete the entire campaign since you will then be given access to all locations without any restrictions. You will be playing as Rookie on a mission titled “Mombasa Streets”. You can then scout the areas easily for these Audio Logs.
It is highly encouraged to keep the VISR vision on since it will highlight the terminals in yellow. While under VISR, nearby alarms, phones and lights will also indicate the presence of a nearby Audio Log.
Without further ado, let us break down the locations for the 30 Audio Logs in Halo 3 ODST. Almost all of these are found within the Mombasa Streets region with only a single log accessible during the Data Hive mission.

Audio Log #30
The final Audio Log for Halo 3 ODST demands you to try out a different map and mission. So exit the game and start the Data Hive stage.
During the mission, you will eventually come across an NPC soldier who will escort you through level 9 and to a frozen area.
While on this route, you will face many Covenant enemies so get rid of them and ensure the soldier does not die since the last Audio Log can only be reached with his assistance.
The soldier will reveal a hidden passage that was previously greyed out on the map. Follow him to the laboratory before executing him for his rogue actions.
Look for the Audio Log #30 in one of the corners of the lab and there you have it, all Audio Logs collected!
You will have earned the “Audiophile” Achievement for your efforts and all bits of story-related details that scratch your Halo’s narrative-focused itches.
