The song is a fast paced piano piece meant to accompany action sequences of similar pace, it later incorporates strings playing a variation of a segment of the Halo Theme.
The track is heard during Uprising, in the section entitled 'Step Aside! Let the Man Go Through', and plays during the opening fight in the canyon leading to the Brute camp. It is the basis of the song Reclaimer.
- If you listen very carefully, you can hear acoustic guitar sounds in the background.
- In the second part of Halo Legends: The Package, a piece of music is used that sounds a lot like Unyielding. It plays during the scene where John-117, Kelly-087 and Frederic-104 are fighting their way through the Covenant ship, and finishes just after John and Kelly are separated.
- This may also be a reference to the base, Unyielding Hierophant, as the song's title is unyielding.
