A fan-made multiplayer mod for The Last Of Us Part 2 has been cancelled by Sony, according to the mod's creator, who received a letter from Sony Interactive Entertainment requesting the project not be released. The mod, which had been in development since January and was scheduled for release this month, aimed to recreate the Factions multiplayer mode from the original The Last Of Us game, adding new features using assets from the sequel. It was partially funded through Patreon, potentially drawing the attention of Sony's legal team due to its use of the company's intellectual property. The mod's creator, known as Speclizer, announced the cancellation on X (formerly Twitter) on September 13, expressing disappointment that the project would not see release. The move has drawn criticism from some fans, who have called it another example of Sony's "terrible decisions," with some users expressing frustration toward the company. However, from a legal standpoint, the action is not unexpected given the mod's use of Sony's IP, which is typically protected under copyright and trademark laws. The Last Of Us Part 2 was originally intended to launch with a multiplayer mode, which later evolved into a standalone title called The Last Of Us Online. That project was cancelled in 2023 by Naughty Dog, the game's developer, which stated that it would have "severely" impacted development on future single-player games. The cancellation of The Last Of Us Online has added to Sony's list of failed live service projects, including a God Of War spin-off and Concord, both of which were also shut down. Naughty Dog is currently working on Intergalactic: The Heretic Prophet, a new single-player sci-fi adventure expected to launch next year. While the studio has not confirmed if it is working on The Last Of Us Part 3, series co-creator Neil Druckmann has teased the possibility of a third game in the series, though no official announcement has been made.
