Three major elements differentiate invasion in Risk 2210 A.D. from classic Risk: limitations in which territories may be invaded, how commanders affect dice, and how space stations affect dice. Players may only invade Water or Lunar territories if they have the corresponding commander in play. Additionally Lunar territories can only be invaded from the Earth game board by a territory containing a space station. Only three of the territories on the Moon game board can be invaded into from the Earth game board. These are the Sea of Crisis, Tycho, and Bay of Dew. Players can not invade from the moon to earth without the "Invading Earth" card found in the Space Deck.
