Ad Fundum throws you into the fragile peace of the post-Great War "Age of Diesel," where hidden dangers lie beneath the earth’s surface. You climb into a towering drilling mech engineered to bore through hundreds of meters of solid rock in seconds. As you tunnel ever deeper in search of precious ores, you’ll juggle fuel levels, temperature control and hull integrity-one wrong move could leave your machine overheated, frozen or crushed by falling debris.
