Welcome to MAN Sector!
Paranoia, the Roleplaying Game of a Darkly Humorous Future, is a role-playing game published by West End Games. Everyone lives in a place called Alpha Complex where they live out their 6 clone's lives in a futile attempt to survive....err....impress Friend Computer, who is constantly looking after its citizens in a (futile) attempt to ferret out Commie Mutant Traitors, who--of course--are trying to destroy Friend Computer, Alpha Complex, and all that they stand for.
Paranoia is great fun, and I, Parody-U-MAN-4, have a few materials available for you to peruse and enjoy.
If you're looking for something to run, or just something to steal ideas from, here's a good starting point. Ultraviolet clearance only!
If you're looking for some documents and graphics that you can use in your own creative efforts, this is a good place to start. Also featuring a Windows verison of an old Paranoia text adventure.
A reasonably complete list of Mongoose's and West End's official published materials for Paranoia.
Here's a pair of bots that you can torture your Troubleshooters with.
