Grand Theft Auto Online isn't a separate download—it's built right into GTA V. But before you can jump into Los Santos with other players, you need to check a few boxes. Xbox Live Gold (or Game Pass Core) is mandatory for any online multiplayer on Xbox, and a stable internet connection is non-negotiable. If you own GTA V—whether on disc or digitally—you already have access to GTA Online at no extra cost.
If you're stuck on the loading screen or get an error, don't panic—connection issues are common and usually fixable.
Contact Rockstar Support with your error code, platform, and a description of what you've tried. They can check for account-specific restrictions or server-side problems.
Once you're in, consider joining a crew, completing the tutorial, and grabbing the free starter properties (like the Auto Shop or Agency) if you have the Criminal Enterprises update. Los Santos is massive—take your time exploring.
