Expansion for Core Game
Race for the Galaxy: Xeno Invasion, an expansion for the RftG base game that comprises the third story arc in the game series, depicts the galaxy as being under attack by waves of violently xenophobic aliens, dubbed the Xenos. XI adds Xeno military worlds (worlds conquered and occupied by them), specific military vs. Xenos, and a new keyword: ANTI-XENO. To provide a good proportion of new Xeno worlds, keyword, and powers, XI is not compatible with the other expansion story arcs.
Xeno Invasion is aimed at intermediate RFTG players, altering Explore to be mix-with-hand. It adds 51 game cards to the base set and includes a bonus Invasion Game, with Produce: Repair and invasion cards, a repulse track, bunkers, and various counters.
