A Game of Strategic Intelligence

Citadel

Fifteen waves. One emerald keep. An adversary that studies your every choice and shifts its host to undo your strategy. Build, upgrade, and adapt — or fall to the siege.

Adaptive AI

The siege director observes your towers and bends each wave's composition against your preferred tactics.

Four Disciplines

Archers, cannons, frost spires, and arcane obelisks — each with three tiers of mastery.

No Two Battles

Hand-tuned waves layered with a director that punishes monoculture defenses.
