Has not been played been in storage in basement. Underwater Cities boardgame removed expansion from listing. Great city builder where your trying to be the one to make the biggest most advance city to win. Great dome pieces and quality components. Complex game to build resource engine to upgrade city to produce more resources to expand. Play is based on hand play of cards that can be basic or special actions that have a given color to be slotted in to action board for effects. 

Great at full player compliment of 4 or as low as 2 players.
