While playing GTA Online you do not have to work alone. At any moment, you can join a crew created by other players. This gives you a spectrum of possibilities and lots of extra fun. Each crew member may choose unique emblems for their group. When being in a crew you can earn extra experience and reputation points. You may also rank-up in the crew hierarchy and, in time, even become its leader. If you cannot find a group that suits your needs, you may create your own and invite friends to fight by your side.
The first thing you need to do before joining an existing crew or creating a new one, is registering in Rockstar Games Social Club.
