For this one we're keeping the d100 spirit but with rules tailored to the Nephilim world. Occult investigations, a revised magic paths system, no individual skills but past lives "packages" used to solve problems. Also we're testing a "roundless" combat system based on post-it notes. All this is still in early "beta" state.
And seeing how the world has changed in the last few years, we have a system to deal with the problem of surveillance and security that require the Nephilim to either find places away from prying eyes to act or deal with Secret Societies' plots to find and expose them.
