you can find now USCSS NOSTROMO 3 decks maps on my deviantart account. We plan to run a scenario based on ALIEN (the film) with my 4 players soon but with some twists in the story and see what comes out of it. Keep posted for the play report and enjoy your games with those Nostromo maps (Class M CM-88H Bison Commercial Towing Vehicule).
