Every Rockstar Studios game comes with the Social Club built in, and LA Noire is no exception. Say what you will about the service, but Rockstar plans to provide users who log into the Social Club with a Chicago Lightning Suit DLC. It can be worn by the game's protagonist Cole Phelps upon his promotion to detective.
Players will also be able to "Ask the Community" for hints and tips when Phelps is interviewing witnesses and suspects, to see how other gamers responded to the situation. The feature requires Intuition Points to use. It's not too dissimilar from asking the audience in Who Wants to be a Millionaire.
Other features include a 100% completion checklist, game statistics and Achievement and Trophy tracking.
