About
Death isn’t the end — it’s how your empire grows.
UNDERWORLD INC. is a dark-fantasy progression game where every life is a new attempt to build a stronger kingdom of the dead.
Play a growing collection of supernatural mini-games to harvest Essence and Souls, improve your abilities, conquer haunted territories, and recruit servants that keep your empire producing automatically.
As your life progresses, more systems open up. Territories generate passive income, servants create powerful synergies, alchemy and special jobs offer new ways to earn, and hidden events can change how a run unfolds.
When your time finally runs out, your temporary empire falls — but your progress is not lost forever. Earn Inheritance, unlock permanent bonuses, and begin your next life stronger, faster, and able to reach further than before.
New challenges appear as you advance through more lives, keeping the journey from feeling the same every cycle.
What you do:
- Play multiple handcrafted mini-games with different mechanics
- Earn Essence and Souls through active gameplay
- Upgrade your character and increase your efficiency
- Conquer territories that generate passive income

Start small in the Ruins, build an automated underworld empire, and see how powerful you can become before the next life begins.
UNDERWORLD INC. — build, die, inherit, repeat.
