Effondrement d'une ville futuriste

Style: 3D cinematic retrofuturistic sci-fi, stylized realism, colossal floating megacity collapsing from orbit, synthwave atmosphere, dramatic volumetric clouds, impossible scale, dynamic camera movement, high-speed action, cinematic destruction, 15-second vertical video pacing Pilot: lone anti-gravity rider in sleek white flight armor with illuminated blue accents, aerodynamic helmet, fearless expression, riding a futuristic hoverbike Camera points upward through thick clouds. A gigantic floating city is breaking apart overhead. Entire skyscrapers drift downward like asteroids. Monorails twist through the sky. The Pilot bursts into frame on a hoverbike, diving through the falling debris field. SFX: atmospheric roar, distant structural collapse, deep synth drone. Tracking shot beside the Pilot racing between collapsing towers. Buildings rotate slowly in freefall. Neon signs tumble through the air. A giant transit station tears apart behind her. VFX: sparks, falling holograms, debris trails. SFX: rushing wind, metal tearing, engine scream. A colossal orbital defense machine awakens among the wreckage. Rotating rings spin around its glowing core. The machine locks onto the Pilot and begins pursuit through the collapsing city. VFX: targeting lasers, reactor glow, energy pulses. SFX: warning alarms, reactor hum, heavy machinery. The Pilot accelerates through an upside-down skyscraper drifting through the atmosphere. Windows explode outward. Debris rushes past the camera as the defense machine fires massive energy blasts through the falling city. SFX: energy cannon discharge, sonic booms, collapsing steel. Epic ultra-wide shot. The Pilot escapes the debris field as the entire floating metropolis ignites during atmospheric reentry. Thousands of burning structures streak across the sky behind her like a man-made meteor shower. SFX: orchestral synth climax, atmospheric burn, final cinematic impact.
