How does gta online expand the world of gta v?

Grand Theft Auto Online is the online multiplayer extension of Grand Theft Auto V. It is developed by Rockstar North and published by Rockstar Games, and was released on multiple platforms starting in October 2013. The game takes place in the same fictional state of San Andreas (based on Southern California) that serves as the setting for the single‑player story. Players can control a customisable silent protagonist and explore the open countryside and the fictional city of Los Santos, which is modeled after Los Angeles. Unlike the single‑player mode, the online component supports up to 30 players who can cooperate or compete in various game modes within the same open‑world environment. This multiplayer expansion enables a shared experience that extends the longevity of the game world by allowing social interaction and collaborative or competitive gameplay.
