There are also tracks that could be heard playing in the Saurian's kickstarter trailer. What it is named and if it is going to be in-game is unknown but it seems to be a variation of the already existing musical compositions, in-game. Other compositions not present in this list seem to be variations of these.
In-game, tracks of various soundtracks of the official OST are randomly played throughout the gameplay, allowing for a more dynamic and often unexpected musical scape, which may change according to the player's status and/or time of the day.
