Audio log (Halo 3: ODST)

Audio Logs are sound files found at various types of data terminals in Halo 3: ODST and are components of a meta-game called Sadie's Story. These logs tell the story about a Kenyan girl called Sadie Endesha during the invasion of Earth in October 20, 2552.

Unlocking Audio Logs will also unlock Supply Caches scattered throughout the level Mombasa Streets. There are 30 logs in total. 29 of them can be found in Mombasa Streets while number 30 can only be found after acquiring the other 29. Number 30 can be found by following the police officer in Data Hive.

Trivia

 * The thirtieth audio log is found in Dr. Endesha's office on the 9th sub-level of Data Hive.
 * Vergil correlates to Virgil, who led Dante through the nine levels of hell, just as Vergil leads Sadie, and then the Rookie, through New Mombasa.
