From the product description this sounded like it would be a great horror adventure for Traveller, where the players are sent by a coporation to investigate one of their mining stations that they have lost contact with. When the players arrive, they discover that the crew of the station made contact with a hostile invisible aliens with some sort of mind control power. The problem with this is that there are no stats for the aliens or the NPC survivors that they encouter! This adventure is not immediately ready for play, which is why I am rating it with only 2 stars, which I think is being generous. Personally, I was disappointed with this product and would have preferred that the hostile threat to be something even more sinister such as a demonic force from another realm, Doom and Event Horizon comes to mind.
