Civilization has lost its history. The first clues to what caused this lie underground. Dig up salvage, upgrade your tools, and explore changing terrain in an incremental excavation to discover what happened.

Recent discoveries have sparked a wave of expeditions. Your assignment takes you beneath the surface, into the remains of a forgotten past.

Recover salvage and excavate the pit to fund the excavation and unearth artifacts left behind by those who came before.

• Choose upgrades across an expanding tree.

• Unlock stronger tools, powerful abilities, and automated helpers.

• Keep digging in one continuous excavation, with no rounds or run timer.

• Explore deeper layers with unique materials and salvage.

• Cut through roots and break harder ground with the right tools.

• Adapt as new challenges change the way you dig.

Keep digging to understand what came before... and why so little remains.
