To celebrate 20 years of this seminal RPG, Catalyst Game Labs is pleased to announce the Shadowrun, Fourth Edition 20th Anniversary Core Rulebook, which includes a host of upgrades for any Shadowrun player. A cover-to-cover full-color treatment allows for a stunning presentation of all the visuals Shadowrun has to offer. While fully compatible with all Fourth Edition-published books, much of the information has been re-presented for better usability. To make this the ultimate core rulebook resource for the entire Shadowrun game line, a 22 page Master Index has been generated and included, covering the 20th Anniversary Edition, as well as the following core rules expansions: Arsenal, Augmentation, Runner’s Companion, Street Magic, and Unwired.
