Rockstar Games have updated their game-linking Social Club hub in anticipation for Max Payne 3, adding new functionality and support for crews, not to mention a whole bunch of expansions upon existing features.
On the new Social Club, gamers can integrate their accounts with Facebook and Twitter, in addition to Xbox Live and PSN. Finding your friends is much easier through this integration, allowing for a much fuller feed. As you can see, I never bothered with Social Club, or I'd have more action items in my feed.
Tomorrow, the Crew system will be unleashed, allowing for early registration in advance of Max Payne 3's release. We'll be banding together in a GameRevolution crew, so check back tomorrow for details on how to join.
