I'm sorry, Citizen. The Fifth Edition was the result of Commie Mutant Traitor interference. It does not exist. It has never existed. All loyal citizens use Paranoia XP. The Computer says so. Doubting The Computer is treason. It is therefore good that you have not read the Commie propaganda that is the Fifth Edition, or would be if the Fifth Edition had indeed happened, which it didn't.
(No, really! They have a rather long blurb about this in the XP rulebook. Turns out there were some 'creative differences' involved, people let go, sectors nuked...that sort of thing. Fifth Edition tended to be closer to what is now called the Zap! style of game, or so my Secret Society contact claims.)
(And our friend GameMaster is using First Ed, which has very little in common with either 2nd or XP. This could be confusing...)
