The Witcher 3's expansive online mod has received a significant update, introducing multiplayer Gwent battles to the game. Version 3.0 of the mod, known as The Witcher Online, now allows players to challenge each other to games of Gwent, mirroring the standalone game CD Projekt Red developed.

As detailed by modder Rejuvenate, players can initiate a Gwent match through an interaction menu when approaching other users. The update includes options for time-limited turns to streamline gameplay and allows players to wager in-game gold on the outcome of their matches. The cards and decks available for play are those collected by the player throughout their single-player Witcher 3 campaign, suggesting that completing in-game Gwent quests beforehand would be beneficial.

The modder noted that while the game doesn't formally support betting on things like piggyback rides across the map, players are free to establish such stakes verbally. With CD Projekt having concluded active development on its Gwent game in 2023, this mod offers an alternative for players seeking multiplayer card game action within The Witcher 3's world. The update also addresses a collision bug that previously affected sitting on chairs in taverns, ensuring a smoother experience when gathering for a game.

To install and play The Witcher Online mod with multiplayer Gwent, players will need a legitimate copy of The Witcher 3 updated to version 4.04, available through Steam or GOG. The Blood and Wine and Hearts of Stone DLCs, along with the Community Patch - Shared Imports mod, are also required. Specific setup instructions are provided by the modders.
