Re: MOON NEXUS

The digital version of the game has a special "demo mode" which allows one to play while the game is downloading; while I don't know what it is called it does take place on the moon and it's possible that this is the level which you are looking for; the bad news is that this game mode (which cannot be completed because it wasn't designed to be finished and which has no effect on your actual game statistics) is not available on the disc version of the game and cannot be accessed again from the digital version once the game has been successfully downloaded.
