Mombasa Suite

Mombasa Suite is the third track in Halo 2: Original Soundtrack, Volume 2, and plays mainly in the Halo 2 campaign level Outskirts. It is composed of Metropole (0:00-1:29), Broken Gates (1:29-4:16), and Encounter (4:16-6:41).

Metropole
Metropole (1:29) begins with a flute solo which echoes the melody from The Last Spartan. It is joined by high strings which repeat the melody. A harp joins in before low strings take over for the conclusion, playing a variation of the Halo Theme. Originally composed for and played during opening of the Halo 2 E3 demo, the piece partially plays in the opening cinematic of the level Outskirts. The piece was rearranged into Skyline in Halo 2: Anniversary Original Soundtrack.

Broken Gates
Broken Gates (2:47) is composed of three sections. The first section features light bass and heavy percussive beats. It plays in Outskirts when the Mgalekgolo break through the courtyard gate, hence the name. It also plays near the beginning of Gravemind, when John-117 reaches where Thel 'Vadam was being publicly tortured in High Charity. It transitions into the second section with strings and vocals. The second section features electric guitar and a male vocal. It plays when Avery Johnson boards the Pelican and John-117 enters an alley occupied by Yanme'e and Kig-Yar Snipers. The percussive beats returns to accompany the electric guitar for the third section. It plays in the encounter with Type-29 Shadows in the highway tunnel at the end of the level Outskirts. The third section was rearranged into Out of Shadow in Halo 3: Original Soundtrack. The third and first sections were rearranged into Moon Over Mombasa and Moon Over Mombasa, Pt. 2 in Halo 2: Anniversary Original Soundtrack, respectively.

Encounter
Encounter (2:25) begins with a percussion version of the second part of Ghosts of Reach. It plays during the "A Day at the Beach" chapter of Outskirts. A transition of strings and vocals lead into a militaristic percussion with a focus on snare drums. It plays during the opening cutscene of Metropolis. The second part of the piece was rearranged into Africa Suite in Halo 2: Anniversary Original Soundtrack.
