Cinematic 4K high-velocity action sequence through a kilometer-long skybridge as it shears apart mid-span. A compact fighter with a wet black braid, a fractal burn across his throat, and a shredded flight liner wields a telescoping spike-baton. He runs the buckling floor, leaps a widening seam, kicks off a tilting column, cracks a plated enforcer across the jaw, spins, elbows a second into the void, drops through a broken panel, catches a cable one-handed, swings, releases, slams into the deck below, and keeps running without breaking stride. Shattering glass and rebar dust hanging in the air as the world falls past, cold white daylight strobing through collapsing structure, the bridge splitting and dropping in enormous sections, plunging vertical tracking camera with snap zooms, undercranked and speed-ramped, realistic freefall physics, extreme motion blur, ultra-high detail.
