GTA Online is now live on Xbox 360 and PS3. When you start up GTA V, you will be prompted with a 59mb download which will add the online functionality to the game.
Once downloaded, you access multiplayer by selecting the fourth player on the player wheel. 16 players will be supported while playing GTA Online, with Rockstar warning to expect crashes, bugs and glitches as they look to release updates and new content over the first several weeks.
In GTA Online, you can take part in heists, own properties and cars, take showers as well as create your very own character.
