"2-4+ player board & card wargame. Each player controls an Advanced Spacefaring Alien Civilization."

Each Alien Race sends its fleets out to conquer the galaxy. Each Race has six attributes which can change throughout the game: Attack, Defense, Movement, Production, Strategic, and Initiative.

The players share a custom card deck containing two types of cards: Technology and Event. Technology cards give a Race a new ability or an attribute bonus that last for the duration of the game. Event cards represent temporary bonuses and effects.

The game is played on a hex map of space filled with ten "terrain" types: Alien Ruins, Star Cluster, Nebula, Super Nova, Black Hole, Dark Matter, Quasar, Worm Hole, Asteroid Field, and Deep Space. Each type of space has a special effect, except for Deep Space which has no effect.

There are two ways to win the game. Either control all the Star Cluster spaces in play or occupy the most spaces when the deck runs out.
