The Witcher 3 Multiplayer Arrives: Witcher Online Mod Lets Players Co-Op as Geralt and Friends

The Witcher 3: Wild Hunt now supports online multiplayer through a fan-made mod, Witcher Online, allowing up to five players to adventure together for the first time. Launched by Nexus Mods creator rejuvenate in January 2026, this modification turns the acclaimed single-player RPG into a co-op experience where players can host or join servers and explore the Continent as Geralt or other fan favourites.

Witcher Online finally makes multiplayer possible in The Witcher 3: Wild Hunt, more than a decade after its original release. Created by modder rejuvenate and available on Nexus Mods since January 2026, the mod enables groups to “lark around with groups of people, chat via text, and perform emotes while you hang around wherever you want in the game,” according to coverage by Eurogamer.net. Although the exact upper limit of simultaneous players remains unconfirmed, official gameplay footage featured “a maximum of five players together,” which currently defines the mod’s practical co-op capacity.

Witcher Online Mod: How Multiplayer Works

The Witcher Online mod allows users to host or join multiplayer servers within The Witcher 3, and the feature supports full roaming across the open world. Multiplayer features include:

• Text chat between players for communication
• Emotes for in-game expression and interaction
• Co-op play through either core quests or freeform exploration, depending on group preference
• Support for a Custom Player Characters mod, letting players take on the roles of notable Witcher 3 figures such as Geralt or Yennefer, with further appearance customisation options

The mod does not require all players to use Geralt exclusively. With additional mods, players can embody “any of the notable characters in the game and tweak the appearance of them,” making it possible to run a party of sorceresses, witchers, or other familiar faces.

To play Witcher Online, players must own a copy of The Witcher 3: Wild Hunt. The modification remains in early development and, as Eurogamer.net observed, can be buggy: “Players in the Witcher Online video seem to frequently fall upwards into the sky. Perhaps it’s to do with conflicts between different instances of the game. Maybe mounting Roach in one instance, but looks like they’re falling into the sky in another instance. It’s a perilous business, horse riding.”

Development, Bugs, and Community Reaction

The Witcher Online mod emerged at a time of renewed interest in The Witcher 3, which first launched in 2015. As of January 2026, the mod has generated excitement among long-standing fans eager to experience the game in a new way. Users should expect technical issues, especially syncing between co-op sessions. According to the Eurogamer report, “it does appear to be rather buggy,” with recurring glitches involving character physics and world instances. Nonetheless, it marks the first time multiplayer functionality, even in an unofficial capacity, is publicly available for the base game.

The Eurogamer article summarises the feature set as follows: “The mod, called simply Witcher Online, makes the game into a sort of MMO-like experience, in that you can lark around with groups of people, chat via text, and perform emotes while you hang around wherever you want in the game.”

• Mod name: Witcher Online
• Creator: rejuvenate (Nexus Mods user)
• Release Date: January 2026
• Player count observed: Up to 5 players currently visible in the official video
• Character support: Custom characters mod enables the use of non-Geralt avatars
• Status: Early, buggy release; ongoing development likely
• Requires: A legal copy of The Witcher 3: Wild Hunt

The mod appears amidst speculation of further official content for The Witcher 3, with Eurogamer stating: “Rumour has it that there’s an add-on or expansion for the 11-year-old game that will launch this year, possibly bridging the gap between The Witcher 3 and The Witcher 4, and possibly taking place in Zerrikania, a desert-like place and biome we haven’t explored before.”

With Witcher Online, players can now transform The Witcher 3’s solo adventures into shared experiences. While technical challenges remain, the mod’s release answers a longstanding community wish and revitalises interest in the game as it approaches a possible new expansion. As always, early adopters should prepare for bugs, but the opportunity to roam the Continent with friends, whether as Geralt, Yennefer, or another, has finally arrived.
