Rockstar tends to show a lot more restraint than other companies when it comes to talking about upcoming games. However, studio co-founder and Grand Theft Auto V co-writer Dan Houser did reveal a fairly major feature for the upcoming GTA.
For one, there will be multiplayer, and Social Club integration will allow players to bring their crews from Max Payne 3 multiplayer over to GTA V's. While Houser isn't going into a whole lot of detail at this point, he notes that multiplayer is an important part of "moving forward" right now:
"Multiplayer is an ever-more important part of all our games moving forward. And by creating crews through Social Club, the crews that you create in Max Payne 3 will be ready and available for you to play in Grand Theft Auto V from day one. It's all part of our larger approach to make multiplayer deeper and richer than what's currently available, much more easily accessible to the newcomer and rewarding for the hardcore.
"We made a promise not to talk too much about forthcoming games until a little further down the track but, yes, crews will feature in Grand Theft Auto V multiplayer."
In Max Payne 3, Crews are basically groups of players that have joined up through the Social Club, going "beyond what's possible by using your Xbox or PS3 friends list," Houser explained in a previous interview. Rolling with a Crew awards certain benefits, like bonus XP for participating in Feuds or just a sense of "safety in numbers."
