In early 2026, modder rejuvenate released The Witcher Online - an unofficial multiplayer mod for The Witcher 3: Wild Hunt.
Thanks to this modification, "The Witcher 3" becomes a multiplayer game about the adventures of a squad of Geralts (or other characters from the franchise).
There are technical nuances: the state of the world is not synchronized, i.e., although players travel together, they cannot help each other with completing quests or in battle (the world will look different for them). But you can communicate and use "emotions."
The Witcher Online mod is distributed for free via Nexus Mods. To run it, you need a licensed copy of The Witcher 3: Wild Hunt (next-gen version, patch 4.04+)
You also need to set up your ownserver and you will need a set ofmodifications, such as "Community Patch - Shared Imports" and "Custom Player Characters"
