One Final Effort is a song included in the Halo 3: Original Soundtrack. It is heard on the level The Covenant when you face the two Scarabs. It is the third movement of the Covenant Suite.

It starts with a piano playing the theme from This is the Hour. It then switches to the Halo 3 version of the Halo Theme. The end is a soft string melody that fades to a close.

It runs for 3 minutes and 8 seconds.

Trivia

• At the end of the 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." This may imply that the Prophet of Truth is encouraging the last troops of High Charity to commit suicide rather than be killed by the Flood, or it could refer to the activation of Installation 05.This could also be the reason on the last part of the bridge before the cut scene on the level The Covenant, all covenant troops are already dead and no flood form will touch them.
• Additionally, at the end of the level Tsavo Highway, Lord Hood tells the Marines "One final effort is all that remains." He is referring to the final defeat of the Covenant. Incidentally, this song plays during the battle outside the Citadel, regarded as the Covenant's last stand. As such, this track plays during the UNSC's 'final effort' to defeat the Covenant.
