Rockstar has confirmed that titles Red Dead Redemption, Grand Theft Auto 4 and Max Payne 3 will be affected by the GameSpy server shutdown on May 31, however the publisher is looking to transition these games to a new online system as a result.
While core online gameplay for these three games will be saved, some features will still be lost. This includes both Red Dead Redemption and Grand Theft Auto 4's Social Club stat tracking, leaderboards and in-game Social Club services. In-game multiplayer leaderboards will also cease to be on the game's PlayStation 3 version. Max Payne 3's online gameplay, on the other hand, will be removed fully on Mac platforms, while Social Club stat tracking and leaderboards will be unaffected.
Sadly Rockstar has confirmed that older releases won't be so fortunate, with those affected being shut down once GameSpy turns servers off. These will include Midnight Club Los Angeles on PlayStation 3, Grand Theft Auto: Chinatown Wars on Nintendo DS and PSP, Beaterator and Midnight Club 3: Dub Edition.
Rockstar has confirmed that Grand Theft Auto V will not be affected by the discontinued GameSpy service.
