The age of robots brings forth a new wave of destruction. The industrial tower looms above the city, as now hostile robots roam the streets, leaving behind a trail of chaos.
This is another favorite sci-fi trope – the post-Apocalyptic City. I’ve chosen robots as the cause of mankind’s cause of destruction. The ominous tower obviously serves as the central headquarters for the dastardly robots. It is also the focus point of any heroic last-of-humanity forces on a last-ditch effort to save humanity.
