The first goal of the team at Saber was to bring the MudRunner experience to consoles in a new improved version. Releasing the best possible base game was the first priority. Now the goal is to fix the last remaining technical issues and bring some of the most requested features in the game (wheel support on consoles and working mirrors in cockpit view are on the list).
We hear your requests about mods on consoles and we understand them. They won't be available in the short run on PS4 and Xbox One. But we plan to support MudRunner in the long run and we'll develop future updates with community feedback in mind.
