Federation Commander has two base games: Klingon Border (which is the same as Federation Commander: Academy + Graduation) and Romulan Border. When placed together, you have ships for the United Federation of Planets and the four major empires that surround them. If you already have Romulan Border and want to add the Klingon and Kzintis, instead of buying Klingon Border (or Academy + Graduation), you can buy this discounted package that includes the non-duplicated parts of Klingon Border, such as the counters, ship cards, reference cards, and a special ship/scenario book. This package does not include the hard-mounted maps, the box, marker, dice.
