Vice is a sourcebook for Shadowrun, Fourth Edition. It provides a detailed look at all levels of organized crime, from the major transnational syndicates—like the Yakuza, the Triads, and the Mafia—to the smallest street gangs and specialist organizations. History, personality, and membership of these groups are provided along with suggestions on how best to use them as key players in a Shadowrun campaign. The crimes they commit, the metahumans they recruit, the law enforcement they oppose, and the shadowruns they sponsor are all in here. Whether your team of runners works in concert with the criminal underworld or tries to oppose it, Vice will offer new insights and options to your campaign.
