Drag. Drop. Dominate.
Early Access v0.1.739 heroes. 17 worlds. Infinite progression. Zero cost.
Build your formation, watch abilities chain across the battlefield, then prestige to unlock permanent upgrades that make every run stronger. With 39 heroes whose abilities interact through positioning, no two formations play the same. During runs you'll collect gear, battle your mounts, mine for bonuses, send heroes on missions, and push deeper across 17 worlds of escalating challenge.
The core that sets this idle game apart
Every hero slot matters. Moving a single hero can transform your entire formation's output.
Experiment with placements, discover synergies between heroes, and watch your damage multiply as abilities interact in ways you didn't expect. This isn't just clicking — it's building a damage engine.
