The Eighth Edition is finely produced with thick cardboard counters and a sturdy thick game board. The rules are in full color (with cartoon) and very well done. This humorously entertaining game pits two players against each other aboard a spaceship. One plays the ship's crew, trying to kill the evil and rapidly-multiplying aliens controlled by his opponent. And although the crew members have several weapons available to them, they don't know what effect those weapons will have until they try using them in combat against the Awful Green Things.
