From the file's introduction Foe Factory: Modern allows GMs to quickly create entertaining and interactive NPCs for their d20 Modern-based games and to rapidly scale those NPCs to challenge Player Characters of any level; without having to rewrite them from the ground up. NPCs created with Foe Factory differ from normal ancillary characters in a few fundamental areas while maintaining essential playability and quick statistical recognition. Mostly, this involves changes to how the NPC’s stat block is presented, how NPC ability scores are generated, and how NPCs gain special attributes.
