The main menu is based on the last map you played. If you want to launch the game with a specific background, then you have to manually change the last map played saved in your config. I don't think you can do it on consoles, but if you are on Steam, open the following file: C:\Program Files (x86)\Steam\steamapps\common\ARK\ShooterGame\Saved\Config\WindowsNoEditor\GameUserSettings.ini And change the following option: [Player.Info] LastMapPlayed=Aberration_P You will need to do that
