'''Dread Intrusion''' is the eleventh track (Disc 1 Track 11) included in ''[[Halo 3: Original Soundtrack]]'', and plays throughout the ''[[Halo 3]]'' [[campaign]] level ''[[Floodgate]]''. It is composed of ''Dread Intrusion'' (0:00-1:50), ''Black Tide'' (1:50-3:43), and ''Old Friend'' (3:43-5:25).

==Overview==
===Dread Intrusion===
''Dread Intrusion'' (1:50) begins with digital chimes and sound effects. Muted percussion enters, leading into a reversed message hidden in the piece, then transitions with digital chimes and sounds. The opening ambiance is played in the beginning of the level, and the reversed message section plays when [[John-117]] and [[Thel 'Vadam]] enter the [[Flood]]-infested [[Traxus Factory Complex 09]].

===Black Tide===
''Black Tide'' (1:53) enters with female vocals singing three phrases in eerily. Percussion enters, followed by vocals and low strings in a rearrangement of the second section of ''[[Ghosts of Reach]]'' (from ''[[Halo 2: Original Soundtrack]]''). This piece plays in the chapter "Shadow of Intent", when John-117 and 'Vadam return to the second lake bed to witness the arrival of [[Fleet of Retribution]] and [[Sangheili]] soldiers being deployed to combat the Flood. The vocals were invoked in the track ''Once More Unto the Breach'' (from ''[[The Pillar of Autumn (music)|The Pillar of Autumn]]'' in ''[[Halo: Reach Original Soundtrack]]'').

===Old Friend===
''Old Friend'' (1:42) enters with eerie ambiance, mixed with various digital chimes. The notes play in no particular melody before they transition softly into high strings. The piece plays when John-117 enters the wreckage of ''[[Indulgence of Conviction]]'' in search of [[Cortana]] and, as the title alludes, meets [[343 Guilty Spark]].

==Hidden Message==
Just like ''Destroyer's Invocation'' from ''[[Mausoleum Suite]]'', when ''Dread Intrusion'' is played backwards, a voice can be heard. The voice sounds and echoes similar to the [[Gravemind]].<ref>[https://www.youtube.com/watch?v=NXX5blfXclU ''YouTube'': Halo 3 - Dread Intrusion Reversed]</ref>
It says:

==Production notes==
*The name ''Dread Intrusion'' alludes to the arrival of the Flood on [[Earth]].
*The name ''Black Tide'' may be a reference to the Flood, whose name usually associates with water.
