Killers by Design 1990

A guidebook for players who want to design their own custom "Killer" cards for the Psychos & Slashers games, Suburban Slasher and Kamp Killjoy. The instructions cover generating the various stats for the Killers plus a discussion of special powers, accompanied by examples. The expansion consists of a four-page folder and a blank Killer character/stats sheet.

—user summary

With the popularity and growth of Psychos & Slashers it seems inevitable that it should transcend the limitations of cards and boards, and that players should be able to move on into the strange borderland between straight strategy games and role-playing. The first step in that direction is a flexible system which allows players to design their own killers instead of having to rely on the traditional assortment presented in the various Psychos & Slashers games.

A customized Killer allows a player to explore his own sick imagination a bit more fully and adds variety and mystery to the game, while taking an important step closer to role-playing and inevitably [sic] release of the Psychos & Slashers role-playing game, though I suspect that when the RPG is released players will switch into the roles of victims rather than killers.
