Mega Supremacy is an expansion set for the Supremacy game. The Mega Map includes a 36' x 48' full color map with 22 new territories and 11 new seas. The map also includes 260 capitals, religious centers, and major ports. The expansion contains new rules for nuking territories, collecting tribute, defending capital cities and religious centers. The Mega Map was intended to be used with the Mega Supremacy: Challenge of the New World Order book which was sold separately. The Mega Map and the New World Order book add a lot of interesting complexity to the game.Expands: Supremacy - BoardGameGeek
