This edition can be distinguished from earlier AH editions from the layout of the box front: e.g. the description ("Game of skill in which negotiation...") was moved from the bottom of the box front to the right of the box.
- 1-piece map
- plastic playing pieces (stars and anchors)
- second edition rules from 1982, but printed in 1985 (according to the date on the back of the rulebook)
