The provided article text does not contain the actual GTA 6 leak report — only PC Gamer's website navigation, membership and newsletter sign-up boilerplate was supplied, with no substantive content about the game itself. As a result, no reliable summary of the claimed leaks (such as key cloning, combat changes or bird deaths) can be produced from this source material.

To provide an accurate, neutral summary, the full article text would need to be retrieved, as the title alone does not offer enough detail to describe what was actually reported or verify its accuracy.
