Illuminati Y2K is an expansion set to the newly-released colour Illuminati: Deluxe Edition. Y2K introduces 76 new groups, 26 new special cards and two new Illuminati: The Church of the SubGenius and the Shangri-La. Most of the new cards depict groups or things that have become commonplace in modern society (the WWW, El Nino, paparazzi) and that fit in comfortably with any conspiracy theory; other cards just add some new oddball organizations (vampires, arms smugglers, chain letters).
