Ironhold - Idle Tower Defense

Now live: the world of Thornveil opens. Command your castle across an unending siege. New Veilwatch invasion every week — start your chronicle today.

One castle. Endless waves. Every rebuild starts higher than the last.

Ironhold is an idle tower defense set in the world of Thornveil, where you command a single keep across an unending siege. Place your defenders. Route your gold. Watch the walls hold — or don't. When the keep falls, the coffers fill, and the next siege begins stronger than the one before.

This is a game of small decisions that compound. Every coin picks a lane. Every upgrade sharpens the loop. Every run teaches you where the walls will break next.

WHAT YOU'LL DO

— Defend across endless waves. Wave 40 is not the end. Wave 400 is not the end. — Recruit from eleven great Houses. Fifty-five named defenders at launch, each with their own strengths and their own price if they fall. — Route your gold across attack, defense, and support. Every siege is a new economy. — Rescue what the walls take. When a defender is captured, you can send others to bring them home. — Return to progress. The keep works while you're away — resources, waves, and stones accumulate offline.

WHAT MAKES IT DIFFERENT

— The roster stays with you. Named defenders level up, remember their wounds, and carry your history across every run. — The Veilwatch turns each week. New invasion scenarios, new leaderboards, new pressure. — Twenty-eight artifacts to unlock, each one bending the siege in a different direction. — No timers standing between you and the next decision.

Ironhold is built for players who want the depth of a strategy game and the pace of an idle one. The walls will fall. That's part of the loop. The chronicle is what you build across every rise and every ruin.
