From the box: Imagine this. First you see some spaceships. Then your mind becomes possessed; you see visions of Devil's Tower in Wyoming; you hear a weird, mysterious 5-note melody; you travel to Devil's Tower only to discover that others have come for the same purpose. You learn that only one of you will be allowed to board. To board the Mother Ship, you must compete against the others in a game, and win. The game. During the game you and your opponents move between Devil's Tower and the Mother Ship. As you move, you try to avoid the hidden traps that your opponents have set for you. At the same time, you try to slow your opponents' progress by creating hidden traps of your own. It's a game of mystery, of concentration, of chance. To play, you'll need nerves of steel. To win, you'll need a few lucky breaks. It's exciting. It's fun. It's unusual. Best of all, it's a game designed to be shared by the entire family.
