宇宙都市：小惑星防衛

“Make a 15-second widescreen science-fiction battle around a gigantic city traveling inside an asteroid storm. Thousands of escort craft constantly reposition rocks as a defensive shell. When an enemy fleet attacks, fighters dive between the asteroids and the city accelerates while escorts redirect enormous rocks into the attackers. A large enemy warship forces its way through and fires toward the city. The city abruptly changes course, carrying the entire asteroid formation with it; the defensive shell becomes a coordinated weapon and crashes into the intruder. End as the city vanishes into the moving storm. Use photorealistic spacecraft, vast scale, rapid camera movement and relentless action, with no text, logos or cartoon treatment.”
