The Computer has generated the following mission for your team. It has been carefully designed to ensure the maximum safety and satisfaction for your team.
Paranoia is the Irrational Fear Someone is Out To Get You(Fear) Dominant type of fear to install in the PCs: The Computer personally likes the PCs too well.
(Irrational) General kind of weirdness or irregularity that prompts The Computer to assign a mission to the Troubleshooters: One or more laws of nature has been altered or revoked. It's gravity.
(Someone) Person, people, organization or agency responsible for the situation: A High Programmer who mis-programmed a CompNode so badly the entire node must be re-imaged and rebooted (the situation is cover for this.) (The identity of the Someone need not be obvious at the mission's outset, and in fact things may play out more appropriately if the Someone is not discovered until late in the proceedings.)
(Out To Get You) General apparent threat posed by the situation, or the consequences if the situation is left unresolved: Endless wave of assassination attempts will befall drugged (thymoglandin, hydropsionic acid), who uses the Troubleshooters as decoys while he protects himself. The threat is real.
Mission Alert: Anonymous hardcopy message slipped under door of PC's quarters. Recognition password (to be given to briefing officer) is wrong. The information is missing, replaced by [INSERT DATA HERE] or similar. Secret society contacts or servile truckling to The Computer may fill in missing data.
Briefing: Briefing is in Proper Bedding Maintenance Hall of Fame. Briefing officer is hiding inside an empty Cold Fun barrel and passes written notes out to the PCs through a small bunghole.
This Mission: Investigate an unexplained disaster in crowded computer interface (IR: public terminals area; R-Y: Computer cafe; G-B: private terminal, I-U: communications nexus).
Outfitting: C-Bay or other online auction site: Price: 50% discount off list price. Delivery: agreed drop point nearby (VIOLET (Tension 18) crowded hangar (or other large room)), immediate. A PC's auction site account has been hijacked by a Computer Phreak using it to auction treasonous warbot plans.
Debriefing: The debriefing officer is dead on arrival, seated at an empty desk in a plain room, and no one arrives to replace him.
Find weird phrasing, clearly erroneous output, or other signs of filthy commie mutant traitor sabotage? Copy the offending passages and email them to the High Programmer for investigation.
