How a run goes

One mountain, one hearth

The miner digging through rock under the fog, a lantern lighting the tunnel

Dig

Every run is a new mountain hidden under fog. Your miner has one long first day to follow the glints, find a cavern rich in minerals and light the hearth there. You only get to do that once.

A walled base around the hearth with ballistas and drill rigs

Build

Monsters can't break rock, so every cell you dig is a way in. Wall each opening with palisades and gates, then hold the walls with Ballistas, Bombards and Shrines. Every building levels up and changes its look.

Night: monsters pressing on the palisades while the ballistas fire

Hold

At night the monsters come, and every night is harder than the last. Brutes break walls, Duskwings fly over rock, Borers dig new ways in.

A boss leading the night's wave toward the base

And then a boss

Every few nights a boss leads the wave. How many nights can you hold?
