What We Know

Confirmed

How the two protagonists work

• Lucia Caminos and Jason Duval are a couple, not two strangers sharing a city. Rockstar has framed them as a Bonnie-and-Clyde pair.
• You switch between them, the way GTA V let you switch between Michael, Franklin and Trevor — but where GTA V gave each lead his own arc, here both share one story.
• Many missions are built for the pair working together, so the switch is a tool inside a mission rather than only a way to change chapters.
• Lucia is the first female lead in a mainline Grand Theft Auto. She is introduced coming out of prison; Jason is introduced as someone already working for drug runners in the Keys.
• Rockstar has since said how the switch works. Outside missions you can swap between them almost any time; in the story, some missions let you switch freely, some make you switch at set moments and some keep you on one of them. During a police search the two can also split up, because the police are looking for a couple.

The shape of the state

• Leonida is a whole state, not a single city: six named areas, from the island chain of the Leonida Keys to Mount Kalaga National Park up against the state's northern border.
• Vice City is the game's Miami, the Grassrivers its Everglades and the Leonida Keys its Florida Keys.
• The Grassrivers wetlands are where Rockstar's own screenshots show airboats, out among the alligators and the fishing spots.
• Mount Kalaga National Park is the backwoods of the state, with hunting, fishing and off-road trails.
• Port Gellhorn is what Rockstar calls Leonida's forgotten coast, and Ambrosia, which it calls the heart of Leonida, is sugar country, with the Allied Crystal refinery and a biker gang.
• The full labelled map has not been published, and Rockstar has given no figure in square kilometres — only comparisons with its own maps, which Rob Nelson gave on a studio visit before the August showing: Leonida is about twice the size of GTA V's and three times the size of Red Dead Redemption 2's.

From the 29 September magazine cover story

• Weather is local and persistent: you can stand in sun while rain falls in the distance, puddles stay after a storm, and hurricanes and tropical storms are in. Rockstar would not say how often they come or whether they touch the story.
• More than 170 animal species, among them over 60 birds and over 30 land mammals, plus fish and reptiles. Animal tracking returns, and there are rare animals Rockstar did not name.
• Side activities named: base jumping, kayaking, jet skiing, airboating, scuba diving, street and off-road racing, billiards, mini golf, gyms and zoos.
• Fast travel is by ride-share car. Robberies can be done alone or as a pair, loudly or quietly, and that choice changes the police response; if either lead is overwhelmed by police, the game ends.
• High-end cars need special tools to steal and may carry trackers; an in-game app, WAiNK, shows a car's resale value and its security.

Not confirmed — and treated as unknown here

• An exact map size. Rockstar has only compared Leonida with its own maps; area figures measured by fans from trailer footage are not Rockstar numbers.
• The mission list, or how the story is structured. The only length on record is Rob Nelson's own: his run through the main story in February, with a few optional missions, took about 80 hours.
• Collectibles of any kind — nobody outside Rockstar knows what there is to find.
• Online, its launch state, or whether it ships alongside the campaign.
• A PC release date. A press report on 13 October put it in the first three months of 2027; Rockstar has not confirmed it.
• Anything sourced from leaks or datamines. It is left out on purpose.
