Rockstar Games has not shared an official look at the Grand Theft Auto 6 map yet. The map from GTA 5 is currently the series' biggest at more than 80 square kilometres, but GTA 6 is expected to beat it. When revealed, expect this to be the biggest map the franchise has ever had.
Looking at roadsigns featured in the first trailer, the following places have been spotted and could potentially appear in the game: Port Vice City, Keys, Vice Beaches, Hamlet, Waning Sands, Port Gellhorn, Vice City International Airport, Stockyard, and Vice City Downtown. These locations could feature across the two counties of Kelly and Vice Dale.
