Ad Fundum

Ad Fundum is set after the Great War, in the Age of Diesel. With peace still fragile, you pilot a colossal mech deep into Earth to find a way to avert future conflict. You drill through hundreds of meters of rock in seconds, collect valuable resources and fly back to your base to sell the minerals for profit. What you find underground may be a boon or a doom for humanity.

Pilot your mech

Monitor your control panel as you mine. The mech can overheat or overcool, needs fuel to operate and can be damaged by falling stones. Its hull can withstand only so much damage, so the underground environment poses a constant threat.

Rebuild and upgrade

Use money to restore your run-down base and improve its mining performance, as well as unlock special abilities. You can also upgrade each part of your mech individually, experimenting with different builds to suit your playstyle.

Explore underground

The game has eight locations, each with its own visual style, atmosphere, gameplay mechanics and threats. The terrain shifts as you dig, and earthquakes make gathering resources dangerous. They can also bring a rain of minerals, tempting you to collect ore while the ground is moving.

You can discover artifacts that reveal the history of Earth's first human civilization, or search for remnants of the previous underground expedition to unlock special mech upgrades with unique effects.

Runs and endings

Each run takes place on a procedurally generated map. Every location has its own music and atmosphere, and the game offers several difficulty levels, including options to customize the difficulty. Different story endings are available to unlock.
