About the game

Tragedy befell the Earth’s surface, forcing civilization to withdraw deep underground near the planet’s core. Scavenge the world below, mine for natural resources, take down monsters, and learn to survive as the last remnants of humanity. Discover a powerful ancient technology and harness its energy to restore mankind and return to the surface.

DIG & EXPLORE

Dig deeper through the inner core with a trusty pickaxe in one hand and a lantern in the other. Detonate explosives to carve a new path or to defend against tunneling terrors, including slithering sandworms, white wolf spiders, and robotic rodents.

BUILD


Make yourself at home as you explore the underground world. A perfect camp can protect you from lurking creatures and provide a safe place to spend the night. Try spicing up your camp by crafting all kinds of furniture. An adventure should not be dull.

FARM


Food is essential, even in this underground world. You can grow various kinds of vegetables, hunt different underground creatures, and experiment with different recipes to create a variety of foods. Tap into your creativity and culinary skills to come up with perfect combinations that will keep you well-fed.

AUTOMATION


Embark on your mining journey armed with just a single pickaxe in your hand. Traverse the depths of the earth and gather resources while exploring. However, why stop there? Utilize the lost technologies you discover to construct your own automated mining and production system. Sit back, relax, and let the machines do the heavy lifting for you.

MONSTER GIRLS


Cultivate friendships with adorable monster girl companions, humanoid hybrids with powerful abilities and supernatural traits. Gain their favor by learning their distinct personalities and make use of their skills on the quest to the surface. Lilith acts as guide providing useful hints and tips, Cartier is an enigmatic wolf girl with a temper, and Mona is wary of humans with the innate ability of self-healing. Activate their gifts in the form of buffs to help in combat and other endeavors.

*All monster girls appearing in the game are aged 18 and above.
