Music

Celestial Protocol uses many different royalty-free soundtracks throughout the map. All of these royalty-free tracks are sourced by two composers: TeknoAXE and Kevin MacLeod.

There is a public playlist on Cavinator1's YouTube channel which contains YouTube videos of most of the music tracks. (There is only track that cannot be found on the playlist)

It is currently not known how music will play, however it will likely function similar to in the Assassin of Steve trilogy. During boss fights there is always one track that loops endlessly until the boss is defeated, while during missions there are a larger set of five tracks. One of these tracks are picked randomly, and when the track finishes, another track is picked to play.

## Composers

### TeknoAXE

TeknoAXE is a royalty-free music composer who specialises in metal, techno, and electronic tracks but also creates tracks of a variety of other genres such as ambience and orchestra. The majority of the music tracks used in Celestial Protocol are by TeknoAXE.

## Trivia

* The track 'Underground Revolution' plays in the second teaser trailer.
* In the official release trailer, the tracks Waypoint P and Maneuvering Thrusters Only are used.
* On Cavinator1's Youtube channel, you can find a playlist of almost all the tracks found in Celestial Protocol. There is only one track that cannot be found in this playlist, and it is **Decade of Epicness** by TeknoAXE. The reasoning behind this is unclear but could be tied to how this is the Supreme Celestipede's theme.
