I am absolutely unable to understand why this adventure has such a low rating. Of course, there are a lot of clichés of science fiction and space horror, but, in fact, what did you expect? Personally, I have received only pleasure while recognised in various scenes familiar moments, clearly inspired by favorite classic books and movies (I would say that there is "Blade Runner" or "Total Recall" meets "Aliens"). The plot, as in all parts of the "Alien" movies is fairly predictable, but again it's a such genre. I put a solid 5 and be happy to play on!
We play in Strange Aeons now and one of our players referred to this book while creating his character. Using these materials, he created incredibly cool and thematic 'hero' (objectively, the best in the group). Shortly after the beginning of our games I read this book and was amazed at the quality of the work. It looks like the best of Paizo's books. My respect to author and advice to everyone - go and take this book, you will not regret it!
