Not much, to be honest. Humans are the norm, cyborgs are also common(Both partial and full). Everyone has P.P.E. of 1d8+M.A. modifier. Definitely an underground element with several figures heading different aspects of criminal activity. They all have an unsteady truce in place by meeting up every week at a restaurant called Brenard's. I also have ideas that would spice up the game. Such as Shifters are actually infected by parasites that slowly transform them into a permanent carnivorous form, always hungry for flesh. They prefer people with high P.P.E. to make the transformation faster, but a high number means stronger resistance to infection. A lower number means easier infection but slower transformations. That's about as much I have for the time being... Other than the fact that it all takes place in a metropolis that has a slums area that even the police and gangs are a bit afraid to enter. Also, no magic.
