From publisher blurb: Onyx Sky explores our world after a devastating global war and environmental collapse plunge humanity back into the stone age. In Onyx Sky, players create characters who've been safe inside a military bunker, government facility, fallout shelter, or scientific vault. After decades hidden away, they emerge from their haven. They find a world in ruin, its communities struggling to endure against roaming marauders, autonomous battle droids, and metal-eating nanites. The players' characters, armed with contemporary knowledge and ideals, are thrust into a world in technological and cultural freefall.
