The Koolian Empire was growing in strength. The massive Ursoids were riding a wave of prosperity as their explorers and fast scout ships claimed world after world. Fear brought a quick end to the squabbling of the other powers and they banded together to prevent a Koolian Hegemony. For a moment it looked like Koolian power would be broken at Barchan. Then the Koolian ship teleported away, and Barchan went nova.
Supernova is a card game of galactic expansion.
As play progresses, worlds are discovered and empires clash through diplomacy, warfare, and economic conflict. While it was originally released as a collectible card game, the current edition of Supernova provides players with the complete set of cards, along with a random assortment of 24 additional cards. These extra cards are extremely useful, as they allow players to customize and modify the central deck slightly between games in order to give each session a slightly different flavor. By changing the card mix you can cause a game to focus more heavily on diplomacy or warfare, or you can make a game centered around specific alien races in order to play out a particular story you have in mind. Supernova can be played with anyone from two to six players, although three or four seems to be an optimum number.
