From the campaign:
Cascade is a supplement for The Veil RPG. A cyberpunk roleplaying game Powered by the Apocalypse successfully Kickstarted last year.
In The Veil, humanity has the technology to perceive both the digital and the physical in a blended, hybridized reality via neurochips that are implanted into almost every denizen of society. This veil that has become the new reality is ubiquitous and pervasive.
It gives you everything you need to extrapolate a cyberpunk future from our present and places interesting, compelling characters that drive the fiction at the center of it all while enabling everyone at the table to contribute what they like about cyberpunk to the fiction.
The Kickstarter campaign is doing well. They're closing in on 2x funded with still 23 days left to go.
