China: Mars, an online-only expansion map set on Mars for the China / Web of Power family of games, deviates from the usual pattern of a network of connected locations by having several disconnected bases on the red planet, changing the road-building possibilities present in other versions of the game. China: Mars also has single locations for two of the card colors instead of only one, altering the value of cards and the challenges of hand management during play. China: Mars launched officially on November 1, 2011.
