I've never played Paranoia, but it sounds awesome. Firstly, is there anywhere I can get an overview of the general rules, or does it mutate so much no-one knows what's going on?
The rules are thus:
There are security clearences from Infrared (black) to Ultra Violet (white). You start at Red, you can touch things that are of your security clearance and lower, and are otherwise not an infrared commoner who is pumped full of happy drugs.
Friend Computer is always right.
Not obeying Friend Computer is treason.
Friend Computer says "Trust Friend Computer"
Friend Computer says "Be happy" (Not being happy is treason)
Friend Computer says that Secret Societies are treasonous, they want to overthrow Friend Computer.
Friend Computer says that mutants are treasonous, as they have powers that can hurt Friend Computer.
Treason is punishable by summary execution.
You're a mutant that belongs to a secret society. So is the rest of your team. You also come in a 6-pack (of clones), and any crimes committed by one are assumed forgiven, as that clone "clearly had errors."
Now go out.
Find trouble.
And shoot it.
(That is: that's all you're allowed to know, it's about 8 pages worth of the rulebook of over 200)
By the way, clever GMs will extend these rules to RL objects. If he throws pens down on the table DON'T pick up the wrong color. I made this mistake once.
