Wiki-GTA6 is an independent fan resource dedicated to Grand Theft Auto VI. It brings together information about the game’s characters, vehicles, weapons, animals, cities, locations, gangs, radio stations, activities, media, products, missions, and map. Its central setting is Leonida, a fictional state inspired by Florida, with Vice City at its heart. The site also covers protagonists Lucia Caminos and Jason Duval, alongside other figures and places connected to the game.

Visitors can browse category entries, read news and guides, explore the game’s history, and join the community forum. The site says it updates its articles as information is confirmed and distinguishes rumors from established details. It also features community contributions and a giveaway. Wiki-GTA6 presents itself as a fan-made guide, not an official Rockstar Games website, and notes that it is not affiliated with the developer. Its goal is to gather and organize available information about Grand Theft Auto VI in one resource, with sections spanning both the game world and the latest coverage.
