CREATE LIFE ON MARS Lead a corporation and launch ambitious Mars terraforming projects. Direct massive construction works, manage and use your resources, create cities, forests and oceans, and set rewards and objectives to win the game! In Terraforming Mars, place your cards on the board and use them wisely: - Achieve a high Terraform Rating, by increasing the temperature and oxygen level or creating oceans... Make the planet habitable for future generations! - Get Victory Points by building cities, infrastructure and other ambitious projects. - But watch out! Rival corporations will try to slow you down... That's a nice forest you planted there... It'd be a shame if an asteroid crashed right on it. Will you be able to lead humanity into a new era? The terraforming race begins now! Features: • The official adaptation of Jacob Fryxelius' famous board game. • Mars for all: Play against the computer or challenge up to 5 players in multiplayer mode, online or offline. • Game variant: Try the rules of the Corporate Era for a more complex game. With the addition of new cards, including 2 new corporations, focused on economy and technology, you will discover one of the most strategic variants of the game! • Solo Challenge: Finish terraforming Mars before the end of generation 14. Try new rules and features in the most challenging Solo mode on the (red) planet. DLCs: • Speed up your game with the Prelude expansion, adding a new phase at the start of the game to specialize your corporation and boost your early game. It also introduces new cards, corporations and a new solo challenge. • Explore a new side of Mars with the Hellas & Elysium maps, each bringing a new set of twists, awards and milestones. From the Southern Wilds to the Other Face of Mars, the taming of the Red Planet continues. • Add the Venus board to your game, with a new Solar phase to hasten your games. Shake up Terraforming Mars with the Morning Star expansion, featuring new cards, corporations, and resources! • Spice up the game with 7 new cards from the Original Promo Pack: Includes everything from the microbe-oriented corporation Splice to the game-changing Self-Replication Robot project. * Try the Big Box Promo Pack and its 23 cards to raise the level even higher. Play as the expert-only Pharmacy Union or enjoy the more relaxed Astrodrill corporation with this DLC! * Establish outposts and trade with them in Colonies! Featuring 49 project cards, 5 corporations, and a whole new game system, Colonies is the most content-packed DLC to date!
