I've read this book and I have to say good! I'm a fan of Alien, Predator and Prometheus series. The rule in this book is really matched on Alien stories because most of rules are concentrated on expressing the sense of space biological horror such as Stress Dice mechanics and Panic Roll. And the rules to simulating the life on space is strongly reflect a truth about how weak our human are among this endless space, like critical injuries, lack of food/water and a number kinds of aliens.
But I suggest that this game could sorted out this large number of rules and enlist a reference sheet to help Players making their Characters or Ships easily. That can save more time and let Players and GMs pay more attention to write stories.
I'm looking forward to more storybooks and new sets to complete the setting of Alien/Predator/Prometheus universe, and I wish this game can publish an official rule for supporting Players to act as Alien, Engineer, even Predator! By the way, we need Chinese and Japanese edition! (^o^)\/
