In June 2009, Mongoose Publishing announced that they would be retiring the books in the XP line to clear the way for the 25th Anniversary Edition line - revealing a new edition of the rulebook as well as two new rulebooks, one casting the players as higher-clearance Internal Security investigators and one as Ultraviolet High Programmers.They stated that the XP material would "maintain a 90% compatibility rating with the new Paranoia books". These included:
- Paranoia: Troubleshooters. Self-contained rulebook for Paranoia games involving Troubleshooter player characters. Includes two missions: Robot Imana-665-C (from the 1st edition Gamemaster Screen supplement), and The Quantum Traitor (new).
- Paranoia: High Programmers. Self-contained rulebook for Paranoia games with Ultraviolet-clearance High Programmers as player characters. Includes the mission Disaster Management.
- Paranoia: Internal Security. Self-contained rulebook for Paranoia games with Internal Security Troopers as player characters. Includes two short introductory missions: Six Clones Before Breakfastcycle (new), and IntSec Agents at the Earth's Core (from HIL Sector Blues, but tweaked).
