The studio will be hosting a series of multiplayer events over the next month through which they'll be randomly selecting participating players for a shot at small-time fame. Rockstar will then contact a select group of participants to give them their shot at competitive multiplayer fame. To be eligible, make sure you've linked either your Gamertag or PSN id to your Rockstar Social Club profile and jump into the Social Club Multiplayer Event playlist during each of the scheduled sessions.
