Cyberpunk lives and dies in the city. The vision and aesthetic that we take for granted as Cyberpunk, especially when considering Cyberpunk in the context of games, is urban, replete with neon, skyscrapers, and bustling crowds of people. Cyberpunk RPGs have leaned into the assumption of an urban setting for some time now, with Night City from Cyberpunk 2020 arguably being one of the best examples in terms of character and development. When approaching the need for a city for the Cyberpunk Chimera, I opted to take a somewhat different path forward. By writing rules for the creation of a city sandbox, my hope is that any group can find a city that sets the tone for their campaign while also making prep easier for the GM.
