Production notes

 * The vocal in the background of Recon was sung by Martin O'Donnell, and he gave the part the name spooky_kid_vox. O'Donnell used format shifting on a harmonizer and shifted his voice to resemble that of a "creepy boy soprano".
 * The name Recon alludes to the reconnaissance mission being conducted by Recon Team Bravo.
 * The name Searchlights references the searchlights on Type-52 Phantoms seen throughout the level.
 * The name Personnel Issues alludes to the presence of militia members in the area despite civilians being evacuated from the area.
 * The name Keeping What I Steal alludes to the player using UNSC weapons stolen by the local militia. The name is also a reference to Cortana's quote in the Halo 3 level The Covenant, "I keep what I steal." The quote was also the namesake for the track Keep What You Steal in the Halo 3: Original Soundtrack.
 * The name Howling Dark may be a reference to the speech made by Lord Hood at the Voi Memorial in the ending of Halo 3, "But let us never forget those who journeyed into the howling dark..." The quote was also the namesake for the achievement Into the Howling Dark in Halo: Reach and Halo: The Master Chief Collection.
