Horrors will have a list of pre-made, classic, monsters and slashers however the GM will also be able to build his own custom Horror to terrorize his players. The Horror is built from the ground up, giving the Horror different traits, weaknesses, and targets. And this all begins by picking an Archetype.
Lots to talk about in this one: Current status of Mars, What went wrong with Directive, What i'm going to do to fix it, and how i'm going to make sure that doesn't happen with Horrors.
