Slave Zero

From the introduction: The First Corporate Dynasty is ruled by the SovKhan, a tyrannical ruler who maintains control over the Asian Conglomerates from the towering factory-city of Megacity S1-9. Rising from the miserable, toxic floodlands created by endless years of pollution, the capital is the largest and most advanced structure ever built by human hands. Stretching miles high into the sky, it houses millions of inhabitants, vast factory complexes, research facilities and even more mysterious structures in service of the SovKhan.
