Natural diegetic sound throughout — gasping, screaming, bus brakes screeching, metal impacts, heavy breathing, distant highway traffic — layered with a tense instrumental score building through the chaos and easing into relief at the end. No text overlay, no watermark. Maximum dynamic camera variety — close-ups, wide shots, tracking shots, slow motion reserved only for the final takedown blows. Realistic shake only during physical impacts, natural daylight highway color grading.
