'''One Final Effort''' is the eighteenth track (Disc 2 Track 3) included in ''[[Halo 3: Original Soundtrack]]'', and plays in the ''[[Halo 3]]'' [[campaign]] level ''[[The Covenant (level)|The Covenant]]'', when [[John-117]] faces the two [[Deutoros-pattern Scarab|Scarabs]].

==Overview==
The piece begins with a low strings note, which is followed by the piano playing the five-note E Dorian melody (from the later track ''[[Finish the Fight]]'') and two variations of the phrase to answer the melody as percussion joins in. Single piano notes and high strings slowly build in tension, and the piano breaks into a more prominent rendition of its part from ''[[Unyielding]]'' (in ''[[Halo 2: Original Soundtrack]]''). High strings join in with a rearrangement of the third section of the track ''[[Truth and Reconciliation Suite]]'' (itself a variation of the ''[[Halo Theme]]''). The piano accompanies the melody throughout, and takes over the low strings ending with the five-note E Dorian melody. A full rearrangement of the original ''Truth and Reconciliation Suite'' section was featured in the later track ''[[Greatest Journey]]'', which was played in the [[Halo (Halo 3 level)|final level of ''Halo 3'']]. That version also uses the iconic choir chant used for the main menu, during the piano climax when the theme is in full swing. 

==Production notes==
*The title of the track likely alludes to the dialogue said by [[Terrence Hood|Lord Hood]] at the end of the level ''[[Tsavo Highway]]''. He tells the [[UNSC Marine Corps|Marines]] that "one final effort is all that remains." He is referring to the final defeat of the [[Covenant]]. Incidentally, this soundtrack plays during the battle outside the [[Installation 00 Citadel|Ark's Citadel]], regarded as the Covenant's last stand. As such, this track plays during [[human]]ity's "final effort" to defeat the Covenant.
*At the end of the level ''[[High Charity (level)|High Charity]]'', the [[Prophet of Truth]] can be heard saying ''"If you are to falter know this: One final effort is all that remains."''{{Ref/Level|Halo 2|[[High Charity (level)|High Charity]]}} This line originates from dialog recording sessions conducted pre-''Halo'' where [[Jaime Griesemer]] is directing [[Jason Jones]] in a painful attempt at a Scottish accent. {{Plain|[http://halo.bungie.net/images/News/InlineImages/jasonjones.mp3 The recording]}} is available on Bungie.net.{{Ref/Site|URL=http://admin.bungie.net/News/content.aspx?cid=922|Site=Bungie.net|Page=Bungie Day Memories}}
