Following the events surrounding "Shy Pluto", two new zones within known space have opened up. The Admiral has promoted two new Captains to the rank of Commodore to command these new space bases and work their sectors!
The Space Base: Command Station expansion allows players to expand their games of Space Base to include two more players and adds "pre-deployed" ship cards to adjust for balance and gameplay with more than five players. Now six or seven Commodores can compete for the promotion to become the Admiral of the U.E.S. Fleet!
The Space Base: Command Station box is designed to be large enough to hold the Space Base base game, the Shy Pluto expansion, and additional future expansions in one convenient storage box!
