GTA 6 is built exclusively for current-gen hardware — PlayStation 5 and Xbox Series X|S — which means Rockstar could design systems that would have been impossible on GTA 5's original PS3/Xbox 360 targets. Here's what the trailers confirm and what the technology enables.
Dual protagonist switching
GTA 5 let you switch between three protagonists mid-game via a radial menu. GTA 6 refines this to two leads — Jason and Lucia. With fewer characters to manage, Rockstar can build a tighter story relationship between them. The expectation is that protagonist switching will be more narrative-driven in GTA 6 — switching mid-mission to play out different sides of the same event — rather than the open-world free-roam swap of GTA 5. Rockstar has not confirmed the exact switching mechanic.
NPC density and behaviour
The trailers show crowds that are noticeably denser and more reactive than GTA 5's pedestrian system. NPCs appear to have individual routines, react to events with more specificity (pulling out phones to film, running in varied directions) and interact with the environment rather than just walking paths. Current-gen SSDs remove the streaming bottleneck that limited NPC count on older hardware, allowing far more characters on screen simultaneously.
Water and swimming
Florida's geography — coastline, wetlands, waterways — suggests water traversal will be significantly expanded. GTA 5 had basic swimming; GTA 6 trailers show characters in swamp environments and coastal areas that imply more nuanced water interaction. Airboats are visible in footage, suggesting shallow-water vehicles will play a bigger role. Whether underwater diving returns from GTA 5 is unconfirmed.
Climbing and traversal
The 2022 development leak (widely accepted as genuine) showed a prototype climbing system more fluid than GTA 5's. Characters appeared able to vault over obstacles, climb walls and navigate environments more organically. Rockstar hasn't confirmed this in marketing, but the scale of Leonida's varied terrain — rooftops, wetland environments, urban streets — suggests improved traversal is a priority.
Police AI and wanted system
GTA 5's police AI was criticised for being simultaneously too aggressive and too easily lost. GTA 6 is widely expected to overhaul the wanted system — potentially adding memory (police who remember offenses from earlier), more realistic response escalation, and better pursuit AI that uses the terrain intelligently. The trailers show chase sequences that look more cinematic and varied than GTA 5's. See our full wanted system breakdown for more.
Vehicle handling
Every GTA improves vehicle physics, and GTA 6 will be no exception. The trailers show boats, motorcycles, cars and aircraft — all appearing to handle with more weight and physicality than GTA 5. The current-gen hardware allows for more complex physics calculations, meaning crashes, suspension and surface interaction should all feel noticeably more grounded.
Dynamic weather and environment
Florida is known for extreme weather — sudden storms, hurricanes, oppressive humidity. The trailers show varied weather and environmental states. Whether GTA 6 will feature dynamic hurricane events or destructible environments is speculation, but the setting practically demands more ambitious weather than GTA 5's Los Santos sunshine.
Mission structure
GTA 5 pioneered heist missions with multi-stage preparation. GTA 6 is expected to evolve this further — the Bonnie-and-Clyde premise naturally leads to two-person heist execution rather than assembling a crew. Whether this means genuinely co-operative mission design (where Jason and Lucia's roles are mechanically distinct) is one of the most interesting unanswered gameplay questions.
Quick answers
Can you switch between Jason and Lucia freely? Unknown. GTA 5 allowed free-roam switching; GTA 6 may be more story-gated.
Is GTA 6 open world? Yes — Leonida is a large open-world state. The trailers confirm multiple biomes and a dense Vice City urban area.
Will GTA 6 have improved physics? Almost certainly, given the current-gen hardware and longer development cycle.
