A second version of the mod was released February 29th, 2008 by members of the Living Dead System Operators team and became known as User Error 2. Consisting of the original 5 levels plus an additional 11 levels for a total of 16 (including cutscenes), it is set after the events of Jet's journey through the computer world in the original TRON 2.0 single player campaign.
Jeremy Powers is an FCon employee with financial troubles. He is given an offer by a former Russian agent, Karl, who promises to get Jeremy out of financial troubles in return for a favor. This favor is to retrieve a file out of the FCon system. Jeremy steals Jet's username and password to infiltrate the server.
