As you play, you make use of Trade to acquire new Ships and Bases from the cards being turned face up in the Trade Row from the Trade Deck. You use the Ships and Bases you acquire to either generate more Trade or to generate Combat to attack your opponent and their bases. When you reduce your opponent's score (called Authority) to zero, you win!

The game consists of: One 80 card Trade Deck, Two 10 card Personal Decks, consisting of two Vipers and eight Scouts each 10 Explorer cards, 18 double-sided Authority cards for keeping score, Two Rules Sheets.
