The leaked version is running on old generation of consoles and more. This shows that these leaks are from GTA 6 Gameplay only.
First observation, shows a duo of male and a female like Bonnie & Clyde. There are other elements also such as time and place travel.
This is really a large scale leak for Rockstar Game & GTA 6 is the most awaited game for fans, so this is BIG for everyone.
