The Watchmen Companion includes the Watchmen- Watching the Watchmen and Watchmen- Taking out the Trash game modules, along with the Watchmen Sourcebook, released in 1990 as part of the DC Heroes role-playing game sanctioned by Alan Moore, and including illustrations by artist Dave Gibbons created especially for the game that expanded on the mythos of the original series. This volume also collects pages from Who's Who in the DC Universe featuring the Watchmen and Minutemen characters, The Question #17 (guest-starring Rorschach!), and a page from the rare, promotional DC Spotlight #1 from 1985 that marked the very first appearance of the Watchmen cast in print!
