Fans revitalize multiplayer project The Last of Us Online after Sony’s cancellation
The initiative to create the multiplayer game The Last of Us Online was discontinued by Naughty Dog, citing the difficulty of maintaining a continuous long-term service. Many studios face challenges when supporting games as a service, which require constant updates and an uninterrupted flow of content. However, the dedicated fan base did not give up, with the modding community taking on the task of offering this competitive mode. An independent developer is currently remaking the popular Factions mode, using the technical foundation of The Last of Us Part II, specifically for computers.
At the head of this venture is Speclizer, an independent programmer already renowned for bringing back features that had been removed from other games. The work began more privately in January 2026, functioning as an internal demonstration where two versions of the character Ellie interacted in the same scenario. The project’s relevance has grown significantly following the recent presentation of a 25-minute gameplay video and the confirmation that it will be released in September 2026.
The initiative has progressed to a stage that resembles the official production of a large developer. Speclizer managed to create interfaces for choosing maps and equipment class customization systems, all integrated into the game environment. To achieve this natural aesthetic, the developer reverse-engineered and employed Widget, a graphical interface engine originally developed by Naughty Dog itself.
Technical progress was recorded over several months, where complex challenges related to network coordination were overcome. The first phase focused on harmonizing visual elements, crawling movements and item management. The next stage addressed the synchronization of environments and elements for combat between players. In conclusion, the final refinement was dedicated to the characters’ running dynamics and detailed animations for passages in tight spaces.
One of the major technical impediments resolved concerns the projectile impact identification system. The original graphics engine of The Last of Us was programmed to disregard the player’s own layer when calculating the trajectory of bullets, thus preventing accidental shots against allies or oneself. This feature caused damage to fail to register when projectiles hit another player, simply passing through them.
The resolution found was to redirect the opposing player’s collision area to the same matrix used by non-playable characters, allowing the system to identify him as a valid target. Additionally, the developer disabled impact responses to prevent interruptions during clashes. Lastly, a custom elimination sequence was coded so that the game would not display the mission failure screen every time a participant was defeated.
After correcting the physics elements, classic features from the original Supply Raid mode were incorporated. Among them are the life counter, an operational radar system and player respawn control. The culmination of this work was the holding of the first genuine one-on-one match within the title. The full version of the project will be released exclusively for the PC platform.
The main challenge for those involved now lies in the legal scope. Sony and Naughty Dog have a rigorous history of defending their intellectual properties, which can lead to project cancellation via copyright infringement notices (DMCA).
