To play the extended game, simply add all cards
marked with a red and white icon on the cards’ lower left
border at the start of setup, including 2 new corporations.

Players start with no extra production of resources. Corporate Era can be combined with any of the other game variants. Corporate Era focuses on economy and technology.

These are projects that do not contribute directly to the
terraforming, but make the corporations stronger, adding
new strategic choices to the game.

Playing Corporate Era makes the game longer and
more complex. We do not recommend it for players new to
Terraforming Mars.
