/imagine --ar 16:9 A post-apocalyptic cityscape, ravaged by war or natural disaster. The scene is dominated by towering skyscrapers, now reduced to crumbling ruins, their windows shattered and their walls scarred. The ground is littered with debris, twisted metal, and the remnants of destroyed vehicles, creating a sense of desolation and despair. In the foreground, a group of soldiers, clad in futuristic armor and carrying advanced weaponry, cautiously advance through the ruins. They are accompanied by a towering robotic mech, its metallic body gleaming in the dim light. The mech, with its powerful weapons and menacing presence, is a symbol of both hope and danger in this ravaged world. The overall impression is one of a bleak and unforgiving landscape, where humanity struggles to survive in the face of overwhelming odds.
