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.
s Game Rules use a streamlined, refined, and optimized iteration of Hero Forge Games' engine:
- Attributes and Skills: The simple attribute and skills system allows players the freedom to create their character.
- Flexible Character Building: Flexible character building and development, with general and martial skills, as well as skill specializations for extra customization.
- Step-Die Progression: Character attributes use step-die progression, starting at d6 and progressing through d8, d10, d12, d16, to d20 and beyond.
- Dice Pool Resolution: The opposed resolution system gives meaningful degrees of success.
