01

What is it about?

Year Zero Engine provides a rules foundation that each game adapts to its themes and protagonists. Forbidden Lands, Tales from the Loop and ALIEN demonstrate different applications; Blade Runner and Twilight 2000 develop other variants. The reference document presents the engine separately from those commercial worlds and settings.

02

At the table

Choose a game and use its variant. Character capabilities and dice resolve actions, with risks and resources determined by that particular rulebook rather than a universal setting.
