There was a PDF for Requiem backers, but also there are new rules coming out for new factions (robots and criminal gangs) and vehicles.
Might also be more scenarios coming - if only for vehicles?
Jack the Ripper is (was) available as a free PDF starter.
The existing 5 scenarios also get 5 different scenery options (sewers, residential, industrial, countryside, forest or botanical garden), so combining the 2 gets you 25 options.
