Yes, GTA 6 is set in Leonida, a fictional state modeled on Florida, and its primary city is Vice City, which is directly based on Miami. The first trailer confirmed this on December 4, 2023, showing neon-soaked streets, palm-lined beaches, and landmarks echoing Miami’s Art Deco district and Ocean Drive. The second trailer, released May 6, 2025, added more Miami-inspired touches: swamps, gated communities, and a bustling downtown that mirrors Brickell.
The August 27, 2026 extended look (26 minutes of gameplay) doubled down on the setting. It showed a detailed Vice City with a working metro, a beachfront amusement park, and street-level activities like nightclubs and food stalls. The surrounding Leonida map stretches into the Everglades-like wetlands and Keys-style islands, but Rockstar has not confirmed the map’s exact size in square kilometers.
So expect a Miami stand-in, not a real-world city. Rockstar has always used fictionalized versions of real places, and Vice City is the established GTA equivalent since 2002’s Vice City. Everything else, like whether the map includes a full Orlando parody, remains unannounced.
