Mankind vs Metal

It is the year 3062. The world is ruled by robots. Fighting robots, nanny robots, cleaning robots, destructive robots. Earth is almost unrecognisable. Half the land is barren and scorched; dead from centuries of the black tendrils of death and war, whilst two huge colonies of Robots live untouched, buried and hidden behind the turmoil.

The entire human population, now also split into two groups dwindled to less than half it's original size within a thousand years.
It's the war between two entirely different beings. One created the other, thinking nothing of it. But things went terribly wrong; nothing could have been worse. Turning on their creators, the other side wage an eternal war.
It's humans versus robots.
The war which was once considered a fantasy, a future myth, things of fantasy stories. But little over thousand years later, it happens for real.
And the humans are losing.
What will happen if the human race dies out? Whatever race, colour, age, gender, it doesn't matter anymore. It's one giant entity against another, two worlds fighting for a new era, and the stakes are just too high.
Nothing matters anymore, except the ownership of the future yet to come.
