As they say, everything is better with friends, and by using the seamless co-op mod in Elden Ring Shadow of The Erdtree, it has never been easier — if the mod works, that is. Let’s get started on how to install it and get into the latest DLC with your fellow Tarnished.
Is the seamless co-op Elden Ring mod working?
As reported in the posts section of the LukeYui’s seamless co-op mod’s site on Nexus, “The current version of seamless (1.5.1 / 2.0.0) does not work with the latest version of Elden Ring“.
Whether you are trying to use this seamless co-op mod for vanilla Elden Ring or the Shadow of the Erdtree DLC, you might run into complications. LukeYui is hard at work fixing the mod so it works on the DLC, so check back in on the mod page to see when it’s up and running.
