Call of Duty: Modern Warfare 2 caused problems for PS3 players on its first day. A fix was issued to correct a trophy problem, which solved one problem and created another. (UPDATED to reflect that the problem was caused by server overload and NOT the trophy fix) A multiplayer issue. A big one. Users are reporting all multiplayer activity “killed” with players unable to join games and get past the matchmaking screen.

[UPDATE: According to a a tweet from Activision support, “We don’t have a hard ETA on the servers coming back up, but the outage is totally unrelated to the patch.” It seems a fix may be in store sooner than the doom and gloom forecast of Friday.]

[UPDATE: Robert Bowling added on his Twitter account, “It’s a server overload not a bug in the code,”, and that a patch won’t fix immediate multiplayer problems. “They’re working to have servers back up ASAP.” “Xbox Live servers are maintained and ran by Microsoft,” Bowling explains. “PSN servers are ran and maintained by 3rd party companies hired to do so.” He says that Modern Warfare 2 multiplayer “will be available as soon as Demonware gets the servers back online ASAP.”]

According to Infinity Ward’s Robert Bowling, PS3 owners can expect a “party invite update by Friday”. PS3 owners are stuck with the campaign mode until then.
