The entire galaxy is in danger, because of aliens who are trying to invade it. You are part of the team which will try everything to repel them. Play billiards against your opponents and throw your characters in different directions to repel them. If one of your characters is out of the table, your opponent will score one point. However, if you manage to eject one of the aliens, you'll get one point. The winner is obviously the one with the most points at the end of the game. Have fun!
