'''Intruders''' is the sixteenth track on Volume 2 of the [[Halo 4: Original Soundtrack]].

==Overview==
The track opens with long, sustained synth drones, laying a deep and unsettling foundation, as dissonant atmospheric sounds like processed strings and sound design elements float above, adding to the eerie atmosphere, a sense of vast emptiness. A low, rhythmic, heart-beat-like pulse enters, low percussion hits, adapted from “Penance” of “[[Delta Halo Suite]]”, giving it a forward momentum. Hints of dissonant strings are heard, alongside melodic brass and synth fragments, simple and repetitive, with a thickening pulse, maintaining the same suspenseful atmosphere.

An abrupt shift occurs, leading to a hybrid orchestra—bold brass fanfare soaring, starting a melody developed from the pulse, which still continues in the background, with powerful percussion and string ostinatos helping to create an epic and heroic theme. Then, the focus shifts slightly, energy lowering; though soaring brass and percussion remain vital, they now carry a broader melody, almost like a statement of rising up, maintaining a sweeping, grand and dramatic intensity.

Following the brass high, the intensity drops significantly, returning to a more mysterious tone reminiscent of the opening but more developed, with noticeable synth drones and arpeggiated figures, a short return of the percussive pulse that evolved into more syncopated rhythmic ideas, and fragmented brass soaring, creating a feeling of anticipation and unease.

Percussion re-enters, with more force, brass stabs punctuating the texture, reintroducing elements from the earlier climax, but fragmented and lacking the same energy. Instruments slowly resolve, with percussion being the last to go out with an impactful hit, leaving only brass to echo the theme, leading to a coda where it ends with a potential resolution—almost abrupt—as if it's a lead-on to something else, wrapping up without entirely resolving the tension.

==Composition==
Starts out with ppp, ends in ff, with consistent use of synthesisers and distortions being defining characteristics. 

From 0:15 to 1:00, the track incorporates a heavily synthesised version of the percussion melody from Penance section of the Delta Halo Suite from Halo 2 Original Soundtrack.

* The strings section of track was remade and mixed with new melodies for [[Meridian Crossing]] from [[Halo 5: Guardians Original Soundtrack]]
