"As of May 31 this year, the multiplayer modes in Crysis and Crysis 2 for PC will no longer be playable," Crytek wrote on its forums. "The conclusion of online multiplayer support comes as a result of GameSpy Technology shutting down all their hosting services. GameSpy have been providing multiplayer functionality for Crysis and Crysis 2 since they launched."
GameSpy announced plans to shut down its middleware servers earlier this month, over a year after it ceased editorial production. The service began as a Quake server search program in 1996 before hosting online multiplayer for hundreds of games. EA said it will shift multiplayer for its older Battlefield games from GameSpy to Origin last week.
