Siege of Lava

Embark on a molten adventure where the gate to the underground reopens and you craft a unique subterranean city. Wield mystical crystals to sustain a warm, secure sanctuary as you build workshops, markets, and camps to drive your economy.

Enjoy idle strategy as you mine by day and trade by night, plan multi-path expansions across mining, commerce, defense, and recruitment, and recruit mercenaries to support your empire. Open an underground restaurant, balance supply chains, and orchestrate a thriving underworld metropolis with every decision you make.
