 Wallis began publishing his own fanzines, first "WEREMAN" and then "Sound & Fury", and got to know game designer Erick Wujcik through the latter; Wujcik introduced Wallis to Kevin Siembieda at Gen Con 22 in 1989, resulting in Wallis writing two books for Palladium Books, "Mutants in Avalon" (1990) and "Mutants in Orbit" (1992).Wallis also began working on his own role-playing game based on the "Bugtown" comics, and in 1992 he brought the game to Phage Press, where it stalled for two years due to creative differences.
