I absolutely love this game, it is a great hidden movement/bluffing game. The ultimate edition comes with everything from previous editions! Also it comes with reusable booklets and erasable markers which is awesome. The game does really well to set up a sense of paranoia, as no one knows who is human and who is alien. And both sides will be reluctant to reveal what they are, as it will let people avoid them. Of course in order to move around you have to take the risk of making noises and showing your location, so you have to be cunning on where you say you are when you can lie. The character cards also each have special abilities, and there are item cards you can find on the map, which give you additional ways to reach your goal. I really love this game, as each session is tense right from the beginning, and it just keeps building up as the turns go by, as you are unsure of peoples goals and keep on suspecting everyone until things are revealed. Then it just gets so tense as it is a race for the humans to get to the escape pods and try to out maneuver the aliens. Highly recommended!
