In a departure from Just Cause 4's main storyline, the soundtrack for JC4's Expanded Content features a trio of different compositional styles and adaptive implementation strategies.
Daredevils of Destruction's racing and demolition derby gameplay features playlist-able tracks that feel at home on a car radio, but can still ramp up and down in intensity based on gameplay, even supporting player decisions like exiting a vehicle.
Los Demonios features base liberation gameplay but with an 80s Body Horror-inspired overlay. To support this, the score features custom synths and samplers built from warped human voices, which ramps up and down as the player progresses through each enemy location.
For Danger Rising, the gameplay and music return to a classic Just Cause 3 style, focusing on the orchestra but with added electro elements to support the new Hoverboard traversal mechanic, as heard in this cinematic:
