As gamers we have done the western with laser pistols, six shooters and steam tech. Shadow run alone has covered more noir ground than MGM did between 1945 and 1955. I hope we managed the horror genre well, and the murder mystery almost always sneaks its way into our campaigns. But do we always know we are doing it? Can genre sit right in front of us an yet go undefined? I think it has happened and a speculative fiction genre of all things.
During battle/war the heads of all slain are decapitated and collected by the slayer. The slayer will clean them up and put them on display for inspection by the commander. Depending on the deads name, rank, and expression on the face held by the death blow-the slayer will be rewarded by gold and/or status.
