''The Matrix Online'' was a MMORPG based on ''Franchise/TheMatrix'' franchise that was made by Warner Bros. Entertainment and Creator/MonolithProductions and was later bought out by SOE. It began beta testing in June 2004 and went live in March 2005 for North American users, and April 2005 for European users. It was eventually shut down in July of 2009, due to low sales.

The Matrix was unique in the MMO market for two major reasons: First was the leveling and skill system. Unlike standard MMO's, where you pick a class and then delve into specializations within that class, The Matrix had a modular system that gave every player access to all of the skills, but only allowed them to pick a certain number of skills in a certain progression at a time. This allowed characters to make unique classes by mixing and matching abilities and weapons and was fairly intuitive despite sounding incredibly complex.

Second was the Live Events. Unlike other MMO events, this one had a specific team designed to act out the roles of the minor characters and contacts during a event.

The story of [=MxO=] was as such: After the death of Neo, the [[TheEmpire Machines]] and [[TheAlliance Zion]] have stopped engaging in open warfare and now fight a cold war in the Matrix proper. The [[TheIlluminati Exiles]], led by the [[TheChessmaster Merovingian]], also joined in the fray, recruiting redpills (PC's) to do their dirty work. The major arcs in the story included the death of Morpheus, illegal codes that turned some redpills into SuperSoldiers, a conspiracy to kill everyone by [[ObviousTrap holding a free concert]], and finally giving everyone [[UltimateShowdownOfUltimateDestiny GM level powers]].

As stated above, the game is now defunct. A slideshow is available at the community website, [[http://www.mxoarchive.net/archives/dn1/thematrixonline.warnerbros.com/web/live/index.html Data Node One]].

!!This game series provides examples of:

* AbortedArc: The story of Neurophyte, a Zion operative who inherited mysterious powers after a run-in with a "killcode." The arc took a few branching paths and set the stage for a new Neo-like character... until Sony took over, laid off the event team, merged servers, and never mentioned the story again.
* PrefersTheIllusion: There's a group of people called "Cypherites" who argue that Cypher was right and that Neo and the people of Zion had no right to decide for the rest of humanity. After all, who would want to live in a dead, post-apocalyptic world that humans themselves were largely responsible for?
* RedEyesTakeWarning: The General at one point employed an army of BlackHelicopter pilots who resemble the Agents, but with glowing red eyes, probably so that everyone knew they were bad.
* UselessUsefulNonCombatAbilities: Cryptography and by extension, the Crypto Tool item were never used once and eventually silently vanished.
