Excavation Earth Second Wave

Excavation Earth: Second Wave is the first expansion for
Excavation Earth. This expansion contains four gameplay modules
that can be added to the base game in any combination. One
of the modules contains two new races. Another module opens
up the deck of Achievement cards. These add a whole new way
of scoring by completing specified achievements before other
players. A third module features the Observation Barge, which
influences both the market and the Survey action as well as
creating another area to compete for end-game scoring. Finally,
players have the option of triggering actions using Wild Cards
specific to each faction in the game.
