The world of technocrats faced an unimaginable tragedy: in an instant, a third of humanity died. No one gives answers to how or why this happened. The Metropolis Technology Development Center is unresponsive, and leading scientists Ethan Myers and Benjamin Hill are listed as missing. In order to save the remnants of civilization, it is necessary to introduce martial law.

Soon, a merciless struggle for dominance changes the world beyond recognition, and to save the future it is necessary to preserve at least some remnants of humanity.
