Project Nemesis is a fan driven website for games that use the One-Roll Engine (like Nemesis, Wild Talents, Reign and Monsters) or Chaosium's Basic Roleplay System (BRP) (like Call of Cthulhu) and the Delta Green setting.
What if Alan Turing solved one more problem and completed one last
theorem? And suddenly higher mathematics was awash in spells,
summonings, and alternate dimensions where forces lived that would like
nothing better than to munch on your brain. Thanks to the
Turing-Lovecraft theorem magic happens, almost inevitably for the
worst.
The British Secret Service (MI-6, the anti-spell branch) has a
unique way of dealing with theoreticians who trip over the right
formulae - they hire them into The Laundry and retire them to
meaningless desk jobs. Bob Howard, however, is a little to itchy for
the passive life. After a lot of trying he manages to get into field
work. Now, as a relief from an irritating boss who counts paperclips
and takes regular attendance, Bob gets to deal with dark forces and
demonic possession.
Or doing magic the high-tech way. In this version of the Pentacle of Power (see Nemesis rulebook) the amateurish chalk sketch is replaced with a homemade optical bench and properly calibrated beam-splitter rig and five prisms, upgrading the original student seance antics to full-blown functionality. The operator also needs a jar labelled Dust from ye Tombe of ye Mummy (prop. Winchester Road Crematorium).
Below are rules for generating PC's that are Cleaners. Cleaners are the chaps who have to erase any trace of the work of covert government monsterhunters - like The Laundry, Delta Green or Majestic-12 - its opponents and any reality incursions invoked by either side.
