Official Grand Theft Auto VI materials identify six areas of Leonida: Vice City, Leonida Keys, Grassrivers, Port Gellhorn, Ambrosia, and Mount Kalaga. Rockstar Games presents the state as the setting that brings together Vice City and other regions in its version of Florida.

The official GTA VI page links Leonida Keys, Grassrivers, and Mount Kalaga to landscapes, characters, and narrative scenarios. Meanwhile, the official image gallery features sets identified as Ambrosia, Vice City, Leonida Keys, and Port Gellhorn, publicly confirming those names.

In a corporate statement dated June 24, 2026, attributed to Rockstar Games, Take-Two Interactive said the story takes place in Vice City, USA, and follows Jason and Lucia as they become involved in a conspiracy spanning Leonida. The document also lists a November 19, 2026 release for PlayStation 5 and Xbox Series X|S.

A report published on September 29, 2026 discusses Leonida through references to Florida and states in its subtitle that Rockstar shared new details about the game. However, the full content was locked behind a subscription when this was compiled; the public excerpt includes a caption about NPCs with more diverse body types and physical traits. Therefore, this observation should not be treated as an accessible official Rockstar statement.

The available materials do not confirm the map size, regional boundaries, additional cities, or features inferred by fans. Those points remain outside what has been publicly presented in the primary sources consulted.
