Water is inescapable in GTA 6. The State of Leonida — a fictional Florida analogue stretching from the neon-lit streets of Vice City to the tropical archipelago of the Leonida Keys — is defined by its relationship with the ocean. You cannot build a convincing Florida-inspired world without making water gameplay feel substantial, and everything Rockstar has shown so far suggests they know exactly that.

The Leonida Keys alone guarantee that swimming, boating, and water navigation will be central to the GTA 6 experience in a way they never were in Los Santos. The question is how far Rockstar is willing to push beneath the surface.

What GTA 5 Offered Underwater

GTA 5 made a genuine step forward in water gameplay for the series. For the first time, players could swim underwater for extended periods, equipped with scuba gear, and explore a surprisingly detailed ocean floor beneath Los Santos. Hidden collectibles were scattered across the seabed, sunken ships offered exploration rewards, and sharks provided genuine danger in deeper waters.

It was a solid system, but it remained supplementary. Underwater sections were optional detours rather than integral gameplay spaces. The water itself looked good by 2013 standards, but the limitations of the generation showed — murky depths, limited draw distance underwater, and no real mechanical depth (pun intended) to the diving system.

GTA 6 launches on PS5, PS5 Pro, and Xbox Series X/S hardware, with ray-traced graphics, advanced rendering, and significantly greater computational headroom. Whatever Rockstar builds underwater, it's going to look spectacular.

What the Trailers Confirmed

The GTA 6 trailers showed extensive water environments that cement just how central aquatic settings are to Leonida. Key observations:

Coastal Vice City — waterfront areas, beaches, and marinas appeared throughout trailer footage. The city's relationship with the ocean is clearly front-and-centre in the design.

The Leonida Keys — trailer shots showed tropical island environments and clear blue water consistent with Florida Keys aesthetics: shallow reefs, islands connected by causeways, and open ocean visible in the distance.

Boats in action — watercraft featured prominently in trailer sequences, including high-speed chases on open water. With 200+ vehicles confirmed, the vehicle roster clearly includes a robust selection of boats, jet skis, and other watercraft.

Swimming sequences — characters were shown in water in multiple trailer moments, confirming swimming remains a core traversal mechanic. The animations appeared smoother and more naturalistic than GTA 5's swimming.

The Leonida Keys: A Water Playground

The Leonida Keys are GTA 6's equivalent of the Florida Keys — a chain of tropical islands extending south from the mainland, connected by long highways over open water. In real Florida, the Keys are famous for:

For GTA 6, the Keys represent a gameplay biome unlike anything in the series. Navigation between islands requires boats or the long causeways. Offshore, the water transitions from shallow reef to open ocean. It's an environment that practically demands rich water gameplay to feel authentic.

Underwater: What We Expect (Speculation)

This is where we move into informed speculation territory. Rockstar has not confirmed specific underwater gameplay features. But the combination of the setting, the hardware generation, and Rockstar's design philosophy makes several things highly probable:

Improved underwater visuals (near-certain speculation) — GTA 6's ray-traced graphics and advanced rendering will almost certainly produce stunning underwater environments. Clear tropical water with light shafts, coral, and marine life would be among the most visually striking environments in the game.

Expanded underwater exploration (likely speculation) — GTA 5 had sunken planes and collectibles on the ocean floor. GTA 6's Leonida Keys setting practically writes the design brief: underwater caves in limestone reef geology, sunken treasure, shipwrecks in the Gulf, and hidden locations accessible only by diving. None of this is confirmed, but all of it fits naturally.

Underwater caves (possible speculation) — Florida's geology is famously porous with natural cave systems, many of which are partially submerged. The prospect of underwater cave diving as a gameplay mechanic — entering flooded cavern systems to reach hidden areas — is tantalising and consistent with the setting, but remains pure speculation.

Improved breath management (likely speculation) — GTA 5's oxygen system was basic. A more developed diving mechanic might include scuba gear as vehicle/equipment selection, varying depth effects, and more complex oxygen management for longer dives.

Fishing (probable speculation) — The Florida Keys are one of the most famous sport-fishing destinations in the world. Given that GTA 5 introduced fishing as a side activity and RDR2 expanded it significantly, fishing from boats or piers in the Leonida Keys seems like a natural inclusion — though unconfirmed.

Water as a Tactical Space

GTA 6's confirmed combat improvements — prone crawling, zip ties, human shields — all suggest Rockstar is thinking more carefully about how players interact with environments. Water is one of the most tactically interesting environments available:

Whether Rockstar commits to any of these possibilities formally is unknown. But the setting makes them all feel inevitable.

Bottom Line

GTA 6's coastal Florida setting makes water gameplay non-negotiable — the Leonida Keys alone demand it. The trailers confirmed swimming, extensive boating, and a world where the ocean is as much a part of the map as the streets. Whether Rockstar goes deep (literally) with underwater caves, expanded scuba diving, and reef exploration is unconfirmed speculation — but everything about the setting points toward the most ambitious aquatic gameplay in GTA history. Bring a wetsuit.
