Obsidian: The Age of Judgement

This core rulebook presents a science-fantasy setting in 2299, where humanity wages war against manifested legions of Hell. The last survivors occupy a fortified city known as the Zone, where corporations compete for control, Daemonic Kults threaten the population, and technology reshapes the human body. Players create and play a wide range of characters, including corporate soldiers, cybernetically enhanced assassins, infernal cultists, and self-proclaimed messiahs. The book includes character-creation rules, systems for designing Daemons and security networks, corporate construction rules, setting history, and the mechanics needed to run the game.
