With the latest release of SnowRunner, Xbox Series X and S have specific versions of the game for those consoles. Currently, only a limited subset of mods are currently compatible and approved for the Series X and S versions, which are smaller right now compared to One X and S build of the game - these are vetted by the game's developers and more will be approved over time.
