Update #3 []: In an important update to the GTA 6 gameplay leak saga, it appears the person posting the clips online has has access to some form of the actual game; they're not just posting videos they've either been sent or obtained.
In another leaked clip, the leaker is seen playing as Jason and shooting into a wall the word "Leek". The leaker in question has put their name, "Cyberleek", all over the clips they've posted online, tying the videos to them. This came after another leaked video of Jason flying over the city, which looks jaw-dropping.
With the Extended Look at GTA 6 on Netflix still a week away, the fact the leaker has access to a build of the game means they could continue leaking gameplay and story content to the Internet. This could raise serious concerns surrounding spoilers, as while the gameplay will be updated and improved in the final build releasing in November 2026, you'd expect the plot and its cutscenes to generally stay the same.
