Can i get gta online for free if i own the story mode?

Owning Grand Theft Auto V's story mode does not grant access to GTA Online. The game's single-player campaign and online multiplayer components are distinct products. GTA Online requires either a separate purchase or, for newer platforms, a subscription service like GTA Plus. This separation allows Rockstar Games to monetize the online component independently. The story mode follows three protagonists in Los Santos, while GTA Online provides a persistent multiplayer world with ongoing content updates and monetization through in-game purchases.
