Terraforming Mars: Hellas and Elysium Expansion
The first expansion for Terraforming Mars, Hellas & Elysium consists of a double-sided game board representing two new areas of Mars: Hellas, which includes Mars' south polar region, and Elysium, which is on the opposite side of Mars' equator. Each of these maps consists of new sets of milestones and awards with relevance for that particular map.
This is not a stand-alone game. A copy of Terraforming Mars is required to play.
