Ares Expedition: Foundations contains additional player boards, cubes, and phase cards so that Ares Expedition can be played with up to six players. This expansion also includes two additional game boards. One is a larger score track. The other adds a fourth terraforming metric: infrastructure. Additionally, there are new project cards that involve the new terraforming metric and a new phase card.

Terraforming Mars Ares Expedition: Discovery adds four new mechanics to base Ares Expedition: awards, milestones, upgraded phase cards, and wild tags. Awards are end-of-game scoring that are granted to the player with the most of something. Three awards are drawn at the beginning of the game so that players know what they will be rewarded for at the end of the game. The player with the most of that item earns 5VP, second place earns 2VP. Milestones are VP that are awarded during the game. They are granted to the player to first achieve the milestone. Milestones are worth 3 VP at the end of the game. Some new project and corporation cards allow players to upgrade their phase cards. Each phase card has two different version that players choose from when they upgrade them. The upgrade gives the player a better bonus when they choose that phase. Some new project cards have a wild tag. Whenever a player reveals this card either from the deck (due to an effect) or from their hand because they are going to play it, that player chooses what tag they want it to be. Tokens are used to keep track of what tag was chosen for the rest of the game.

In Terraforming Mars Ares Expedition: Crisis, players will play as corporations, just as in the original Ares Expedition. You choose phases and play project cards as normal. The difference is players are working together to keep Mars habitable after a natural disaster has landed the planet in crisis. Every round, a new Crisis card will be drawn that will require the players to achieve a certain goal to remove that crisis from play. Each turn that a Crisis card is not completely dealt with, it will lower one or more of the terraforming metrics that keep Mars habitable. Handle all the crises as they arise. Eventually, a Crisis card will be drawn that allows the players to win the game once they have completed re-terraforming Mars.

The biggest & most strategic expansion to Terraforming Mars, Turmoil introduces the political struggle for control of Martian society. Turmoil, the fifth expansion to Terraforming Mars, takes players back to Mars, and the struggle for control and progress of human society on a big and dangerous planet. The expansion includes new corporations, new projects, and a new type of cards — Global Events, from dust storms to riots to rising alloy demand — that give you something to plan for. Please note that Terraforming Mars: Turmoil should be considered an EXPERT expansion. This expansion adds a distinct, new level of play as players vie for control of the Terraforming Council, as well as plan for the Global Events. This expansion will appeal to those who want to play a more expansive game of Terraforming Mars.

In the 2400s, mankind begins to terraform the planet Mars. Giant corporations, sponsored by the World Government on Earth, initiate huge projects to raise the temperature, the oxygen level, and the ocean coverage until the environment is habitable. In Terraforming Mars, you play one of those corporations and work together in the terraforming process, but compete for getting victory points that are awarded not only for your contribution to the terraforming, but also for advancing human infrastructure throughout the solar system. 1-5 playersAges 12 to adult2 hours playing time
