While The Elder Scrolls V: Skyrim is traditionally a single-player game, fans have often wished for some form of co-op or multiplayer. The Skyrim Together mod was the most successful attempt at delivering on this, but it would seem that Bethesda might be looking to implement multiplayer elements in a more official capacity with The Elder Scrolls VI.
The Elder Scrolls 6 was announced alongside Starfield all the way back in 2018. Starfield is only just coming out this year, meaning the next Elder Scrolls game is likely at least another five years away. Bethesda is currently hiring for its Elder Scrolls 6 development team and the wording of one job listing suggests Bethesda is exploring adding multiplayer.
The job listing (via Tech4Gamers) is for an Associate Level Designer at Bethesda's Montreal studio. The listing does not specifically mention The Elder Scrolls 6. However, it does call for someone with experience using the Elder Scrolls Construction Set, the tools Bethesda uses to create content for its games. The position also calls for someone familiar with open-world multiplayer games.
The Elder Scrolls IP has dipped into multiplayer territory before with The Elder Scrolls Online. However, if this job listing was for ESO, it would be based at a Zenimax Online studio and since the game is already available, it would also likely be labelled as a job listing for ESO, rather than having the position shrouded in secrecy.
With all of that taken into consideration, it does seem that Bethesda is exploring adding multiplayer to The Elder Scrolls 6 in some form. Whether or not such a feature comes to fruition still remains to be seen. Bethesda also explored multiplayer ideas for Fallout 4, but that ended up being spun off into its own project, ultimately resulting in Fallout 76.
KitGuru Says: I think more RPGs should consider adding co-op gameplay, but have it handled in a similar way to Larian's cRPGs, allowing for each player to vote on important decisions as you progress through the story.
