The background music for this game had the same song with select instruments missing, or notes cut out, in the Planning Phase while the full track plays during the Action Phase. While the Planning Phase is softer (no drums, but hi hats; no melody, but random hits of the trumpet/violins) and meant to evoke a clock ticking, the action phase is inspired by Metal Gear Solid music.
