Hellas & Elysium is the first expansion for Terraforming Mars. It features two new game boards which can be played instead of the main game’s Tharsis map.
Elysium takes players almost to the opposite side of Mars’ equator, with vast lowlands for oceans in the north and a dry, mineral-rich south. Place a tile on Olympus Mons, the highest peak in the solar system, to gain three free cards!
Hellas, the southern wild, includes Mars’ south pole and the enormous seven-hex Hellas crater that just begs to become a giant lake. Building around the pole gives you new placement bonuses in the form of heat and possibly even water.
