Suburban Warzone Invasion Scene Setup

the prompt

[CINEMATIC SETUP]
Big-budget sci-fi blockbuster, invasion thriller, handheld
documentary-style action camera, desaturated cold color grade
with ash-grey atmosphere, overcast daylight, suburban warzone
realism, Spielbergian ground-level perspective, 35mm anamorphic.

[CHARACTERS]
The Boy: ordinary young man around 20, short messy brown hair,
dirty grey hoodie and jeans, scraped face, sprinting in pure
panic, unarmed.
The Aliens: exactly 2 quadruped alien creatures, sleek elongated
bodies, thin spider-like limbs, pale grey-green chitinous skin,
fast unsettling insectoid movement.
The Survivors: 6 armed civilians and one police officer —
handguns, shotguns, hunting rifles, one sniper rifle on a car roof.

[LOCATION]
A devastated suburban street running left to right. SPATIAL
LAYOUT: The 2 Aliens enter from the far LEFT end of the street.
The barricade of overturned cars and furniture, defended by The
Survivors, is at the far RIGHT end. The Boy runs from left to
right, ALWAYS moving away from The Aliens and toward the
barricade. Smoke columns, debris, ash falling like snow.

[TIMELINE]
[0:00–3] Side tracking shot, left to right — The Boy sprints
rightward down the street toward the distant barricade, the 2
Aliens bursting through smoke behind him on the left, gaining
ground.
[3–6] Side tracking continues — The Survivors at the barricade
on the right rise and take aim past The Boy, the 2 Aliens
closing in behind him on the left, one leaping over a flipped car.
[6–9] Side tracking continues — The Survivors open fire from the
right, bullets cracking past The Boy on both sides as he keeps
running right, sparks off wrecked cars, the lead Alien stumbling
as rounds punch into its body.
[9–12] Reverse angle from behind the barricade — The Boy dives
over a car hood into cover among The Survivors as they unload
everything, the sniper dropping the lead Alien mid-leap in a
spray of dark fluid.
[12–15] Slow push-in over the barricade — the second Alien skids
to a stop in the haze down the street, shrieks, and retreats
into the smoke, The Survivors holding aim, The Boy panting
against the car beside them.

[SFX]
Pounding alien footsteps, ragged breathing, deafening mixed
gunfire, bullet cracks and ricochets, sniper shot echo, alien
shriek, falling ash silence at the end.

[MUSIC]
Tense low brass and string ostinato building, cutting out at the
shriek, single sustained note over the final shot.

[QUALITY ANCHOR]
Photorealistic 4K, exactly 2 alien creatures throughout the
entire clip, consistent screen direction (The Boy always moving
left to right, away from The Aliens, toward the barricade),
realistic ballistics, accurate creature locomotion, stable
character and creature design, no flicker, no deformation,
no morphing.
