FromSoftware has released a new patch forElden Ring: Nightreignthat fixes two major battle-related bugs, and it’s mandatory to install it in order to play online.
Elden Ring: Nightreign Gets Patch 1.01.5
Players ofElden Ring: Nightreignare eagerly waiting for the two-player co-op mode to become available. It’s one of the promises FromSoftware made following the game’s strong commercial performance, as this feature was cut during development forPlayStation, Xbox, and PC.
Elden Ring: Nightreignhas proven to be a sales success, surpassing 3.5 million copies sold and becoming the best-selling game in the U.S. in May 2025.

This gives the green light for new characters (or classes), environments, weapons, and bosses to be added to the multiplayer spin-off in the future. And, of course, it also means updates will come more frequently than they did forElden Ringand itsShadow of the ErdtreeDLC.
Patch 1.01.5 forElden Ring: Nightreignis now available onPS5, PS4, Xbox Series X|S, Xbox One, and PC—just two weeks after update 1.01.4, which still didn’t deliver on the promised co-op mode.

This is amandatory updatein order to play online, so keep that in mind. It focuses on fixing two key bugs that affected boss battles in the game.
Here are the two main changes introduced in update 1.01.5, now available for download across all versions of the multiplayer Soulslike, via Bandai Namco’s website:
