Seedance 2.5 摩托车快递员逃离被黑暗吞噬的城市提示词

Create a 30-second ultra-realistic AAA third-person open-world survival gameplay sequence centered on a desperate civilian evacuation from a modern city being consumed by an unexplained phenomenon. The sequence must feel like authentic next-generation gameplay rather than a cinematic trailer, with continuous player-controlled movement, responsive traversal, environmental destruction, dynamic civilian AI, contextual interactions, believable physics, persistent environmental changes, objective updates, and a consistent HUD. Build the thirty seconds around one uninterrupted escape story with strict cause and effect. The player begins as an ordinary motorcycle courier racing toward the final evacuation train while a mysterious moving wall of darkness consumes the city several blocks behind. A traffic disaster blocks the road and forces the player to abandon the motorcycle, the abandoned motorcycle accidentally creates a route through a damaged storefront, that route leads through a collapsing shopping complex, falling debris forces the player underground into maintenance tunnels, the tunnels unexpectedly provide a shortcut to the station, and the player reaches the platform just as the final train begins leaving. The apparent escape becomes the final twist when the darkness stops pursuing the train and something enormous moves inside it. Do not explain the phenomenon. The player and audience should understand only that it is approaching, it is dangerous, and nobody knows what exists inside it. Player Character: [courier] is a young adult civilian with an athletic but ordinary build, short dark hair, tired features, practical dark trousers, sturdy running shoes, a high-necked long-sleeved charcoal shirt beneath a weather-resistant orange courier jacket, gloves, a compact backpack, and a scratched motorcycle helmet during the opening section. The clothing remains fully modest, practical, weathered, and appropriate for someone who has already spent hours navigating an evacuation. The character is not a soldier and carries no firearm. Gameplay relies on driving, sprinting, climbing, vaulting, sliding, squeezing through damaged environments, making rapid route decisions, and using ordinary objects when necessary. Set the entire sequence inside one geographically continuous modern metropolitan district during late afternoon beneath a strange storm-darkened sky. The evacuation route begins on a wide commercial avenue surrounded by apartment towers, office buildings, elevated railway infrastructure, storefronts, abandoned buses, stalled cars, emergency barricades, digital signs, scattered luggage, and thousands of civilians moving toward the central railway station. The station should be visible intermittently ahead through the urban canyon so the player's destination remains geographically understandable. Several blocks behind the player, an enormous vertical wall of unnatural blackness advances slowly through the city. It should not resemble smoke, fog, fire, or a conventional storm. It behaves like a vast absence of light swallowing streets and buildings while leaving only faint distorted silhouettes visible inside it. Streetlights disappear as it passes. Windows vanish into darkness. Sound becomes strangely muffled near its boundary. Never show what happens to people overtaken by it. Use premium photorealistic next-generation AAA rendering with physically based concrete, glass, steel, asphalt, cloth, skin, vehicle paint, rainwater, smoke, dust, and debris. Include dynamic global illumination, realistic reflections, volumetric atmospheric effects, responsive crowds, destructible environments, procedural debris, vehicle suspension physics, cloth simulation, detailed facial animation, persistent environmental damage, realistic momentum, and smooth responsive gameplay animation. Maintain a consistent HUD with health and stamina upper-left, compact navigation map upper-right, contextual traversal prompts near interactable objects, current objective beneath the map, and a distance indicator showing how far the player remains from the evacuation train. Keep dialogue extremely limited. Most storytelling should come from gameplay, emergency signs, crowds, environmental changes, objective updates, distant public-address announcements, and the player's physical reactions. [00:00-00:05] GET TO THE STATION Begin immediately in active third-person gameplay behind the courier riding a motorcycle at high speed through a wide evacuation avenue while the objective reads: REACH CENTRAL STATION TRAIN DEPARTURE: 00:28 The player weaves between abandoned vehicles and groups of civilians while emergency lights reflect across wet asphalt. Overhead digital signs repeatedly display: FINAL EVACUATION TRAIN CENTRAL STATION IMMEDIATE DEPARTURE The camera remains close behind the motorcycle, responding naturally to steering, suspension movement, acceleration, and collisions rather than behaving like a cinematic chase camera. Several blocks behind, the unnatural black wall advances between the skyscrapers, swallowing intersections one after another. Civilians glance backward before running faster, immediately establishing why everyone is moving in the same direction. The station's illuminated glass roof becomes visible ahead. Then a city bus loses control across the intersection. [00:05-00:10] THE ROAD CLOSES The bus crashes sideways across the avenue directly ahead, striking several abandoned vehicles and completely blocking the route toward the station. The player brakes hard, but the motorcycle clips scattered debris and slides across the wet road. The courier separates naturally from the motorcycle, rolls across the asphalt, immediately pushes back onto their feet, and transitions from driving into player-controlled sprinting without a cinematic interruption. The objective updates: REACH THE STATION ON FOOT Behind the player, the damaged motorcycle continues sliding under its remaining momentum and crashes through the glass frontage of a closed department store beside the blocked intersection. The impact destroys the storefront window. A contextual route marker immediately appears through the opening: SHORTCUT The player turns toward the exact hole created by the motorcycle and sprints through it while the crashed bus remains visible outside, making the alternative route a direct consequence of the failed motorcycle escape rather than an unrelated path conveniently appearing. [00:10-00:15] THROUGH THE BUILDING The player enters the damaged department store at full speed, vaulting a fallen display counter and weaving between abandoned shelves while emergency lighting flickers overhead. Civilians who discovered the same route run through nearby aisles, creating believable crowd movement without preventing player control. Through the enormous windows behind them, the black wall reaches the intersection where the motorcycle crashed. The exterior disappears into darkness. The building begins trembling. Ceiling panels fall behind the player while shelves topple progressively from the approaching disturbance. Instead of stopping for a scripted collapse sequence, the player keeps moving as the environment dynamically fails around the route. The courier jumps over a fallen beam, slides beneath a partially collapsed security shutter, then reaches an escalator leading toward the station-side exit. A violent structural impact shakes the building. The ceiling collapses across the exit before the player reaches it. The direct route is gone. The floor beneath a nearby service corridor fractures, revealing maintenance stairs descending underground. The navigation marker immediately reroutes downward. [00:15-00:20] BELOW THE CITY The player races down the maintenance stairs into a narrow subway service tunnel while the destruction continues above. Dust pours through ceiling vents and distant impacts travel through the concrete as the darkness passes across the district overhead. The station marker now shows only a short distance ahead. The courier follows utility lights through the tunnel, splashing through shallow water while pipes shake and loose cables swing overhead. A maintenance gate blocks the final section, forcing the player to sprint toward a low opening beside it, slide across the wet floor, and pass underneath before continuing without breaking momentum. Ahead, daylight and station lighting appear through an emergency stairwell. The public-address system becomes audible through the walls: "Final train departing." The objective immediately changes: BOARD THE TRAIN The courier accelerates toward the stairs. [00:20-00:25] DON'T MISS IT The player bursts through an emergency door directly onto the central station platform. The final evacuation train is already moving. Its rear carriage passes the player as the platform fills with abandoned luggage, flashing warning lights, and a handful of civilians who arrived seconds too late. The courier immediately turns and sprints alongside the accelerating train. The stamina meter rapidly decreases. The third-person camera stays tightly behind the player while the train gradually gains speed, preserving the feeling that the player is actually controlling the chase rather than watching a scripted sequence. A maintenance ladder on the rear carriage approaches. A contextual prompt appears only when the courier reaches jumping distance: JUMP The player launches from the edge of the platform and catches the lowest rung with both hands. Momentum violently swings the courier backward. One hand slips. The stamina bar reaches almost empty. The player activates the climb input, allowing the courier to regain the rung, pull upward, and climb onto the narrow rear platform as the station begins disappearing behind the train. The objective updates: ESCAPE THE CITY [00:25-00:30] IT STOPPED Player control returns immediately as the courier stands on the rear platform gripping the railing while the train accelerates away along elevated tracks. The enormous wall of darkness reaches the railway station behind them. For the first time since the opening, it stops. It does not cross the station. The courier slowly turns toward it as the player's camera remains controllable. The darkness stands motionless between the buildings while rain continues falling around its boundary. The evacuation train increases its distance. Then the silhouette of something impossibly large begins moving behind the black surface. At first it resembles the shadow of a building. Then it bends. A gigantic shape rises above the surrounding rooftops from inside the darkness, but its complete body remains hidden. Only enough movement is visible to prove that something enormous has been traveling inside the phenomenon. The player's objective flickers. ESCAPE THE CITY disappears. A new objective replaces it: FIND OUT WHAT FOLLOWED YOU The enormous silhouette slowly turns toward the departing train. Cut only when the player still has control. The entire sequence must function as one continuous playable escape story rather than six disconnected action scenes. Every route change must be caused by something established immediately beforehand. The player rides toward the station because the final train is leaving, the bus crash eliminates the road, the motorcycle accident opens the storefront, the storefront becomes the new route, the approaching phenomenon destabilizes the building, the collapse blocks the street exit, the damaged floor reveals access to maintenance tunnels, the tunnels lead directly beneath the station, and the player emerges close enough to attempt boarding the departing train. Maintain strict geographical continuity throughout the full thirty seconds. The station remains ahead of the player from the opening avenue, the department store sits beside the blocked intersection, the maintenance tunnels continue in the same direction beneath the district, and the emergency stairs emerge directly onto the station platform. The player must never teleport between environments. Maintain persistent environmental consequences. The crashed bus remains across the avenue, the motorcycle remains inside the shattered storefront, broken windows stay destroyed, fallen shelves remain displaced, collapsed ceiling sections remain where they landed, dust continues entering the underground tunnels, and the damaged district remains visible from the departing train whenever geography allows. The mysterious darkness must remain spatially consistent and always approach from behind the player's route until the final reveal. Never place it ahead of the player simply to create another dramatic shot. Its steady advance is the pressure driving every decision. Do not reveal the creature inside the darkness before the final seconds. Earlier movement may create subtle vibrations or distant structural sounds, but the player should reasonably assume those effects are caused by the phenomenon itself. The enormous moving silhouette at the ending should therefore reinterpret what the player has experienced without explaining exactly what the creature is. The player character is an ordinary civilian whose abilities remain grounded. Movement can be athletic because this is AAA gameplay, but avoid superhero jumps, impossible parkour, combat expertise, magical powers, or unrealistic physical strength. Animations should emphasize desperation, exhaustion, imperfect landings, hurried vaults, heavy breathing, and believable recovery after impacts.
