FBI Agents working in conjunction with officials from NCsoft's North American business successfully closed down a computer game operation alleged to be reaping profits by providing a fraudulent service to its players. The operation was closed down after multiple raids and interviews were conducted in various cities from California to Virginia.

Federal search warrants were served on owners of L2Extreme who were also questioned during the raid. L2Extreme was providing its users with unauthorized service and code for NCsoft's online computer game, Lineage II. The warrants enabled officials to halt L2Extreme's operations while collecting further evidence in the course of the investigation.

The FBI estimates L2Extreme has up to 50,000 active users on its service. NCsoft estimates that monetary losses and damages from the operation are costing NCsoft millions of dollars per year.
