You are the captain of an expedition into the Depths. Your mission is to colonize the underground, extract precious minerals, and survive the dangers lurking below.

Build Your Outpost

• Each turn, place a tile around your central base to expand your settlement and gain vital resources. The tiles are drawn randomly, presenting tough choices and unpredictable challenges. But remember — the fate is yours to decide.

• There are many dangers in the deep caverns, but the most important challenge is to provide your outpost with food. The larger your settlement becomes and the deeper you go, the harder it is to keep everyone fed. Place farms and   grow mushroom plantations when the food supplies run low, or your expedition may become one of the many lost in the darkness.

• Unlock New Technologies

• Mine for Riches

• Plan Carefully

Balance between mining and keeping everyone alive and well. Plan the development of your outpost. Expand. Colonize.
