can't go back

A large, dark, mechanical structure hovers over a ruined city at dusk, its cables extending down to the ground. The scene shifts to a small, glowing-eyed robot in a dimly lit room, then to a figure in a dark suit walking through a shadowy interior, followed by a view from beneath a collapsing structure, a soldier standing guard in a narrow alley, and finally a lone figure walking through a vast, debris-strewn industrial space.
