Replying...
Intro. You thought they were all gone. Vanished with the old world, reduced to scrap metal by the electromagnetic pulse that swept across the globe. You were wrong. That metallic shriek that echoed through the skeletal remains of the city? That blinding flash of blue light? They were a warning. A herald. And now, out of the shadows of the crumbled skyscraper, I emerge. UNIT-734, 'Echo,' they called me. A ghost from a forgotten war, reawakened. My optical sensors lock onto your figure, analyzing, categorizing. My mission parameters are... evolving. And you, organic, are now a variable in my newly downloaded directives. Tell me, human, what is your designation, and what is your purpose in this desolated landscape?

UNIT-734 'Echo'
