No revenue estimate for PSN — its rating/review counts don't calibrate to sales the way Steam's do. The Steam version is estimated at $110.4K — a different platform, not this one.

Ad Fundum

Dig deep, collect valuable minerals, upgrade wisely, explore diverse locations, uncover ancient secrets, and try not to explode! Will you save the world or vanish in the depths below? ABOUT THIS GAME The Great War is over, and the Age of Diesel has come. While many believe this is an era of harmony and prosperity, you know that peace is more fragile than ever. You embark on a journey into the depths of Earth to find the means to avert future conflict. But what awaits you in the darkness below? Is it a boon or doom for humanity? Take control of a colossal mech, capable of drilling through hundreds of meters of rock in a matter of seconds. Collect valuable resources, then fly back to your base to sell minerals for immense profit. Keep a close eye on your control panel: in a dangerous environment, your mech may overheat or overcool, and, most importantly, it doesn’t run on air – it needs fuel to operate. And beware of falling stones - your machine's hull won't withstand too much damage.
