Above ground, your siege crew never stops. Below, a river of gems waits for a clever hand. Carve the ground, feed the crusher, and turn glitter into power every wave.

Build your run one decision at a time: funnel more crystals for a bigger budget, then pick the perk that defines the next fight. Use a firearm with a powerful attack spike, build up your health, or tip the scales to send enemies flying. Sometimes the Devil himself will strike with a tempting choice, choose wisely, and grow in power

Between battles, forge the hero you want. Merge and level gear, complete themed sets, and unlock juicy passives for both the hero and the catapult. Chapter by chapter, your humble sling becomes an engine of ruin.
