Seedance 2.5 Combat Mech Attacks Troops Cinematic Realistic Prompt

30-second ultra-photorealistic cinematic military sci-fi action video, 16:9. A massive autonomous quadruped combat mech attacks adult soldiers in a rugged mountain battlefield. Extremely fast-paced nonstop action, realistic physics, continuous loud battlefield sound, no slow motion. [0–7s] Soldiers sprint through a narrow rocky mountain pass as the enormous four-legged armored mech charges over the ridge behind them at terrifying speed. Heavy mechanical feet smash rock, throwing dirt and stones everywhere. LOUD metallic footsteps, hydraulic machinery, soldiers shouting, alarms and roaring mountain wind. [7–15s] The mech locks onto the soldiers and opens fire while rapidly advancing. Integrated cannons erupt with enormous muzzle flashes. Explosive rounds hammer rocks and mountainsides around the fleeing soldiers, creating violent fireballs, sparks, shattered stone and huge dust clouds. DEAFENING cannon blasts and explosions echo through the valley. [15–23s] Camera races alongside the soldiers as the mech bounds across broken terrain behind them, firing repeatedly. Explosions tear across the mountain trail in rapid succession, throwing debris through the air. A massive blast destroys a rocky outcrop, sending stone tumbling down the slope. Relentless gunfire, mechanical roars and thunderous impacts. [23–30s] Soldiers dive behind huge boulders as the mech charges directly toward them. Its weapons unleash a devastating final barrage. Multiple explosions erupt across the mountainside as dust and smoke engulf everything. Camera shakes violently from the concussions. The gigantic mech emerges through the smoke, weapons glowing hot. Aggressive tracking camera, realistic military movement, heavy-machine physics, practical-style explosions, volumetric smoke, flying rock and debris, cinematic mountain scale, gritty photorealism, directional audio, deep bass impacts, mechanical servos, cannon fire and explosive echoes. No gore, visible injuries, slow motion, music or text.
