From publisher blurb:
Welcome to the world of the Shadowmarkets, a place where you can find a drug for every possible desire. From illegal narcotics to experimental super-soldier serums and zombie-creating nerve gas, if you can smoke it, snort it, or inject it, you’ll find it. You’ll also find new feats, equipment, and advanced hero options for characters in the drug trade and for the agents of the law who stand against them.
The Shadowmarkets is a drug-themed expansion for the Everyday Heroes game system. Since Everyday Heroes is a 5e based game, the game mechanics can easily be used in other 5e systems. This sourcebook is divided into two parts. Part 1 is primarily for players and has a host of Hero options themed around the conflict between drug traffickers and law enforcement. The highlights are two new Career Paths: Drug Trafficker and Police Officer), and two new Classes: Supercop and Juicer. Part 2 is primarily for Game Masters and includes rules for playing with drugs, a list of exotic Shadowmarket drugs, and tools to create new drugs for your games.
