Shadowrun is a cyberpunk-urban fantasy cross-genre role-playing game, set in the years 2050-2070 following a great cataclysm that has brought use of magic back to the world, just as it begins to embrace the marvels (and dangers) of technologies such as cyberspace, omnipresent computer networks, genetic engineering, and the merger of man and machine called cyberware. Despite its departure in some respects from the "mainstream" cyberpunk genre, Shadowrun is perhaps the best-known and most popular RPG for this genre.
