Game description from the publisher: Little green men are a product of the imagination? That's what these spacemen thought until they learned otherwise during a trip to the moon. Once they arrived there, the alien Ansgar had a lot of fun trying to scare the little space travelers. In Kraterschreck im Mondversteck, you don't know exactly when Ansgar will spring forth from a crater once again – only that he'll definitely do so at some point! The players travel on the game board in a circle with their three spacemen, and depending on the roll of the dice, they move not only their own characters but also Ansgar, who moves invisbly amongst the craters. If Ansgar pops up in a crater close to any spacemen, they'll scatter, leaving the moon to others. Whoever has the best memory, a little luck with the dice, and the longest lasting spacemen will win!
