Post-Apocalyptic Soldier Fights Drones in Ruined Factory

the prompt

A lone ex-soldier in damaged body armor with a cracked helmet and glowing wrist device + 0–4s: moves silently through a dead industrial zone while drones scan the ruins; 
- enemy machines detect him, explosions erupt, he fights through robots with EMP blasts, shotgun shots and brutal hand-to-hand takedowns; 
- activates a final pulse that drops every drone from the sky, standing alone beneath falling sparks as the camera pulls back over the destroyed factory
Post-apocalyptic sci-fi action, sparks, smoke, practical explosions, dynamic tracking, final silence after chaos.
