The dwarfs broke into a cave deeper than any before it. Inside it our scouts found an open rift, a portal to somewhere else. The King of the Mountain gave one order: send a crew, build an outpost, and extract everything you can. You arrive with four workers and just enough supplies to last the first few days. The rest is up to you in this punishing game.

To keep your outpost running, you'll need to build and upgrade key machinery. Choose your upgrades carefully; resources are limited, and every level could mean the difference between progress and collapse.

The deeper you drill the more your madness will rise, beware of the depths. There are creatures that will use your madness to locate your outpost and if that happens no amount of Mythril will appease them.

When you send dwarfs to events their stats will act as a modifier on the dice. Make strategic decisions on who you send as if their health drops too low or they go mad the outpost will be doomed.
