As mentioned over in our forums, and on the Dark Conspiracy Facebook page, a 4th Edition of Dark Conspiracy is to be released in 2018! To be produced by Patric Götz (of the German RPG company Uhrwerk Verlag or Clockwork Publishing for us English speakers) it will update the setting and system to modern sensibilities.
A placeholder website is already in place with some details – see dark-conspiracy.com and we will endeavour to learn more as further information comes to hand.
