A low complexity space battle card game. Each player is in charge of an invasion fleet of alien starships. The goal of the game is to destroy enemy starships while landing your ground forces to capture planets. Using a simplified version of the Modern Naval Battles system, each player/race also has a special power that changes the rules for him. One player has cloaking devices, for example. The box leaves the impression this was to be the first of a series of games (as with Modern Naval Battles) but no expansions or sequels were ever published.
