Exactly the same as first edition, except with a revised rulebook. At least some copies were sold with both 1st and 2nd edition rulebooks included. In addition, the game name is printed on the top and bottom ends of the box. The first edition did not have that printing. Also, the 2nd edition included a bar-code on the bottom with ISBN #0-911605-80-0 on top of the bars and 4570800817 at the bottom of the bars.
