Terraforming Mars: Ares Expedition – Foundations

It’s recommended for games with five or more players, but you can also use it with fewer players; doing so makes the game last longer. If you play without the track, remove the project cards marked with the infrastructure icon (p. 3).

With the infrastructure track in use, all four terraforming metrics must be complete: all oceans faceup, oxygen and temperature maxed out, and infrastructure maxed out. The game ends in the phase when the last of these is completed (p. 4).

Each time you increase infrastructure, gain 1 TR and draw a card. You can raise it with a project card or by taking one of the two standard actions (p. 4).

Spend 15 MC to raise infrastructure 1 step, or spend 5 heat and 3 plants to raise it 1 step. Either way, you also gain 1 TR and draw a card (p. 4).

Use the black and white cubes and phase cards for the additional players, and place the supplemental score board beside the main board. It provides extra room for score cubes; when a score goes below 5 or above 25, move that cube to the main board’s score track and continue there (p. 3).
