Just ran this. The soundtrack is totally appropriate for the setting. The real life countdown clock heightens the tensions and adds another element beside room activated events. The VTT assets weren't used since mothership is mostly theater of the mind, but I wished I did use them. 

Would definitely run this again for any group; super beginner friendly.
