Conspiracy X is a role-playing game (RPG) originally released by New Millennium Entertainment in 1996, and since revised and released by several publishers including Steve Jackson Games and Eden Studios, Inc.
In all versions, the setting posits that aliens are insiduously taking over the world, reminiscent of The X-Files.
The current version is based on the Unisystem, but previous versions have used GURPS  and its own system.
Setting
A secret American government agency called AEGIS has been aware since the Roswell Incident of 1947 that there is an extraterrestrial presence on Earth, characterized by supernatural and paranormal phenomena.
Player characters take the role of AEGIS operatives, usually disaffected government agents employed by real-world organizations such as the FBI or ATF or an organization created for the game, such as the Defense Tactical Information Center or Project Rasputin.
The game also touches on many modern popular conspiracy theories including the CIA involvement with psychics and the alien cover up from MKULTRA.
The game can also be run to focus on paranormal happenings such as ghost sightings or ESP.
First Edition
The first edition was originally published as a 224-page softcover book by New Millennium Entertainment.
Eden Studios acquired the rights, their first RPG, and continued to use the first version, which went through several printings, with the Third PrintingRevised carrying a copyright date of 1997.
Many supplemental books were produced for this line including books detailing alien technologies and races, books for dealing with the supernatural (as it is defined in the Conspiracy X world) and books on the governmental agencies featured in the core book (AEGIS and Black Book, also called the NDD), as well as a book on how to create conspiracies and the Bodyguard of Lies series, three books with miscellaneous additions to the world and rules as well as missions to roleplay.
This edition features an original rules system.
Character generation is via a "point-buy" system, where players are given 100 points to divide amongst basic abilities as well as skills and resources.
The player can also purchase more points by adding disadvantages to the character.
For example, adding "Wanted by the Law" to the character nets another 20 points to spend.
Players then act communally to plan "the Cell", the base of operations they will be using for the adventure, including details of location, facilities, staff, and equipment.
Actions are resolved with one of only four probabilities:
Easy (100%)Automatic Success (if your skill exceeds the difficulty level)
Medium (58.3%)Success on rolling 7 or lower on 2d6 (if your skill is equal to the difficulty level)
Hard (16.7%)Success on rolling 4 or lower on 2d6 (if your skill is a single point lower than the difficulty level)
Impossible (0%)Automatic Failure (if your skill is more than a single point lower than the difficulty level)
There are also resolution systems for non-skill actions, competitive actions, extended actions such as research, and use of specific powers and abilities using the core resolution system as a base.
Difficulties range from 1 to 5, and sometimes higher for very difficult actions.
Players can also try to use their character's psychic abilities by utilising Zener cards (square, star, cross, wave or circle).
If a player wants to use his character's psychic ability, perhaps to foretell the future, the player names one of the symbols; the gamemaster draws a number of cards corresponding to the character's psychic ability and turns them over.
If one of the cards is the symbol predicted by the player, the psychic action succeeds.

Reception
Andy Butcher reviewed Conspiracy X for Arcane magazine, rating it a 9 out of 10 overall.
Butcher comments that "Conspiracy X is the most impressive first roleplaying release in a long time, and it's a great game.
It combines a setting and style that will be familiar enough for players and referees to easily understand with an incredibly detailed and atmospheric background, clear, simple rules and an impressive range of original and clever ideas."
In the August 1996 edition of Dragon (Issue 232), Rick Swan characterized the first edition of this game as "the latest entry in the Aliens Walk Among Us sweepstakes, and it’s also the best."
Swan criticized the combat system, which he found overly complicated for a game that supposedly discourages combat in favour of investigation; but he admired the game concept called The Cell, where players must agree on the details of their base of operations.
Swan also liked the use of the Zener Test for psychic abilities, calling it cool that "the character’s success depends on the player’s real-life 'psychic' powers.
Neat, eh?"
Swan, having only playtested the game through one adventure, was unwilling to give un unqualified recommendation.
"But our introductory scenario revealed no serious flaws.
More importantly, it generated a table-full of satisfied customers, hungry for more.
In a 1996 reader poll conducted by  Arcane magazine to determine the 50 most popular roleplaying games of all time, Conspiracy X was ranked 23rd.
Editor Paul Pettengale commented: "By far the best of the modern-day horror games inspired by The X-Files, Conspiracy X has a meticulously constructed background which combined reality and fiction to create a frighteningly plausible setting.
Reading through the background is enough to spark ideas for scenarios and even whole campaigns.
The rules are simple and quick, while still allowing for a fair degree of complexity, and feature a unique and interesting system for dealing with psychic powers.
Excellent stuff."
In 2001, Sarah Hollings published a review of the first edition of Conspiracy X for the on-line roleplaying magazine Places to Go, People to See.
Hollings liked the game, but found some of the rules around dice rolling overly complicated.
"The damage system is frightening.
The words daunting and confusing also spring to mind...
There are some really good ideas in the combat system, and the underlying concepts are not complex.
However the rendering of these ideas into a game mechanic has resulted in a very complicated and clunky system, in places unworkably so."
While calling for updated rules revisions to replace the ad hoc house rules most gamemasters would need to employ, Hollings nonetheless recommended the game, saying, "There is a lot to like in Con X, as a system, and as a world setting.
Yes, the mechanic sucks in many ways; yes, it often borders on unplayable, but nonetheless the work needed to come to a workable understanding (read 'house ruleset') is ultimately worth it for the fun you can have."
