The Fan-Made Last of Us Part 2 Multiplayer Mod: Everything We Know

Nearly three years after Naughty Dog officially abandoned The Last of Us Online, a single modder is quietly building what the studio could not. Speclizer, a creator known for earlier The Last of Us and God of War mods, has spent much of 2026 developing a full multiplayer mod for The Last of Us Part II Remastered on PC . The project is still unfinished and buggy, but its ambition — a faithful recreation of the classic Factions experience inside the sequel's engine — has drawn sustained attention from the gaming press and a community that has long wanted a return to the series' multiplayer roots .

Who Is Making It and When Is It Coming?

The mod is being developed by Speclizer, a modder and YouTuber who has previously released mods for The Last of Us and God of War on PC . Work began in early 2026, shortly after the PC version of The Last of Us Part II Remastered launched on April 3, 2025 . Speclizer has been posting regular development updates and gameplay tests on X (formerly Twitter) and YouTube throughout the year .

Speclizer has stated that the mod's planned release date is September 2026 . A 25-minute gameplay demonstration was published on June 22, 2026, showing the project in its current state, including the matchmaking menu, map selection, and a full 4v4 match . The creator has been transparent about the mod being "quite buggy" and a work-in-progress .

PvP Modes and How They Work

The mod aims to recreate the Factions multiplayer experience from the original The Last of Us within Part II's engine. The primary mode is Supply Raid Team Deathmatch, a mode carried over from the original game's multiplayer . Matches are designed for up to eight players in a 4v4 format. Both teams share a pool of twenty total lives. When a player is killed, they respawn after a 5 to 15 second delay. The goal is to eliminate the opposing team's shared lives. When one team's lives are depleted, the remaining players enter a "Sudden Death" phase .

Speclizer first showcased a basic 1v1 PvP match in May 2026 before expanding testing to full 4v4 team-based gameplay . The mod also includes a custom menu called "Starlight" which, beyond matchmaking, includes features like a model changer and NPC spawner, suggesting potential for broader customization .

Cooperative Story Mode

In addition to the competitive PvP mode, Speclizer has been developing a two-player cooperative story mode that allows a second player to experience the single-player campaign alongside the host . Early demonstrations showed two Ellies navigating the game world together . The co-op story mode work actually began before the PvP component and has been showcased in multiple progress videos throughout early 2026 . It remains in development alongside the PvP mode, with no separate release date announced . Speclizer has noted that involving NPCs makes implementation "a lot harder," which is part of why the co-op mode has been a longer-term challenge .

A Direct Response to Naughty Dog's Cancelled Spin-Off

The mod is widely reported as a direct fan response to Naughty Dog's cancellation of the official The Last of Us Online (often called Factions 2) multiplayer spin-off in late 2023 . Naughty Dog confirmed the cancellation after roughly four years of development, stating that continuing the multiplayer project would have required the studio to dedicate all its resources to supporting it as a live-service game, severely impacting development on future single-player games . Multiple outlets frame the Speclizer mod as the unofficial realization of what Naughty Dog's cancelled project was meant to be .

Platform Limitations

The mod is PC-only. It requires the Windows version of The Last of Us Part II Remastered, which was released on April 3, 2025, on Steam and the Epic Games Store . It does not run on PlayStation 5, and no console version is planned, as mods cannot be deployed on the PS5 in the same way .

A Final Caveat

This is an unofficial fan project, still in active development. The creator himself has described it as "buggy" and unfinished . All plans — modes, features, and the September 2026 release date — are subject to change as development continues. For a project this ambitious built by a single person, delays and feature cuts are always a possibility.
