A fan-made multiplayer mod for The Last of Us has reportedly reached a "big milestone" in its development, as its creators continue preparations for a planned launch in September. The project is being built by fans rather than developer Naughty Dog or publisher Sony, aiming to bring competitive or cooperative online play to the acclaimed single-player franchise, which matters to the community given that an official standalone multiplayer title, previously known as Factions, was cancelled by Sony in 2023.

Unfortunately, the specific details of this milestone, such as what feature or stage of development it represents, were not available in the retrieved article content, which consisted primarily of website navigation and subscription elements rather than the story itself. Readers interested in the mod's progress, its scope, or how to access it ahead of the stated September release should consult the original PC Gamer article directly for the full details.
