Skyrim on the Xbox Game Pass can be modded by hitting 'enable mods' on the Game Pass app, which gives the player access to the Skyrim Special Edition folder and the game's executable. Not only that, but the available collection of mods is also far more limited. For PC players who want to start modding, they need to download a mod manager like Vortex, follow a tutorial on getting started, and begin making changes to their version of the game. The process for downloading mods on the Xbox Game Pass version of Skyrim is slightly different to the process for modding on PC, however.
Recent Xbox versions of Skyrim have allowed for some modding.
