Production notes
The first "Recovered Files" audio log was hidden in the February 2021 issue of Inside Infinite on Halo Waypoint. The audio file was embedded in a comment by 343 Industries' World Design Lead John Mulkey, mentioning that Installation 07 has "stories to be found" - alluding to the audio logs in Halo Infinite. A similar audio was released as a hidden part of the Discover Hope trailer.
