How does gta online expand on gta v s universe?

GTA Online is an extension of the single‑player world introduced in GTA V, providing a persistent online environment where players can join each other in the same city. The game builds on the original setting by enabling cooperative and competitive gameplay, allowing users to form crews, complete shared objectives, and influence the virtual economy. While the core map, characters, and storylines remain the same, the online mode offers a framework for continuous updates that introduce new content, allowing the community to experience the world in ways the single‑player experience does not.
